Mirror-polished stainless steel / High-gloss polished stainless steel

When it comes to high-gloss or mirror-polished stainless steel surfaces, mirrorINOX offers traditional and new, pioneering solutions for applications in architecture, yacht- and shipbuilding, for the automotive and electrical industry, medical technologies, container- and silo-manufacturers, machinery and engineering, aerospace and many more.

Even for the most demanding art projects, mirrorINOX`s polished quality is selected by the artists and designers.

What is mirror polished stainless steel used for?

In principle, we differentiate between technical applications, which require for instance the lowest possible roughness (Ra value) of the requested surfaces.

Such properties play a major role especially in the container- and silo-manufacturing, mechanical engineering, food and medical technology, where adhesion to the stainless steel surfaces has to be avoided by using material that bears a maximum of smoothness.

Other customers request certain reflectivity from the metal finish, for example in the lighting industry. A mirror finish best reflects their demands.

Another more and more popular use of the mirror-polished stainless steel sheets is found in architecture, shop-fitting, ship- and yacht-building, where the focus is very strongly set on an optically first-class result in terms of the visual quality of the stainless steel sheets.

Adding to its flawless appearance, more advantages are the low weight ratio compared to glass mirrors, the very good workability and, immensely important when used in public buildings or other highly frequented locations such as trains stations, airports and others, the properties of break-proof, fireproof and vandalism-proof protection.

Mirror-polished stainless steel of the highest quality

mirrorINOX is your ideal and competent partner for all polished stainless steel surfaces of the highest quality: High-gloss polished, mirror-polished and various other levels of surface treatment.

However, since the very common terms "high gloss polished" or "mirror polished" often do not provide a very clear definition of the product, mirrorINOX defines its self-produced and distributed mirror-polished surfaces in several quality levels such as Mirror No. 7, Super Mirror No. 8, Marine Mirror No 9.  and Perfect Mirror No. 10®, in order to create more transparency for the customer when inquiring and more clarity when ordering the material. That way, you choose your preferred mirror finish to your liking.

What is the best way to polish stainless steel? Here is how we go about it

During the mechanical polishing, the surface is removed by our polishing lines and the help of polishing agents to create a finish as flat, smooth and flawless as possible. Only after that, the actual mirror polishing takes place.

Depending on the base material, base surface finish, various machine parameters and processes, different results (qualities) can be achieved. The measurable values such as roughness and gloss plus the visual impression and approval serve as the base of control.

Mirror polished stainless steel: Applications for yachts and more

Especially with the design applications in the field of architecture, yacht, shopfitting, lighting and furniture construction, the high quality products manufactured by mirrorINOX are in great demand.

Whether we polish stainless steel for yachts or shops: You can always expect the highest quality from us. Even in the extremely quality-sensitive sector of art, our products are well known and highly recognized by most of the famous artists, however they like to remain anonymous. Mirror-polishing stainless steel is our lifeblood and we treat it as such, aiming to achieve the perfect level of mirror finish.

BEADS MAIN

Bead blasting stainless steel by mirrorINOX

In many fields of expertise, high-quality applications increasingly request a uniformly matt, very homogeneous surface, which should not only be non-directional but also bear little to no reflectivity.

Such a decorative and functional surface is created by blasting onto metallic materials such as stainless steel, aluminum, and even non-ferrous metals like brass or copper at a very high speed with glass beads or with alternative blasting media of various bead sizes.

Glass bead blasting stainless steel: What are the applications?

In general, these timelessly elegant and visually attractive, metallic surfaces are used in the fields of architecture, elevators, facades, shop-fitting, ship-, yacht-building and works of art. As such, bead blasted stainless steel has many applications within countless professional fields.

They can also be found in high-quality machinery and industrial engineering.

mirrorINOX uses stainless steel sheets with dimensions of max. 2,000 mm (width) max. 6,000 mm (length) and max. 30 mm (thickness) for its bead blasted finishes.

What is glass bead blasting?

The terms “glass bead blasting”, “bead blasting stainless steel” or “bead blasted stainless steel” commonly refer to the surface treatment of sheets or workpieces where blasting a media such as glass beads, ceramic beads or corundum beads hit the material.

The size and roughness of the blasting media, the pressure and the speed during the blasting process can be altered in order to achieve different results in terms of visual effect, reflectivity and roughness. As such, bead blasting is a very flexible process at mirrorINOX, leading to high quality results.

Glass bead blasting vs. sand blasting: Different methods of blasting stainless steel

For the visually less demanding requirements of industrial and heavy industrial applications, material like stainless steel or other metals are requested very frequently, resulting in different blasting processes such as those using sand ("sand blasting") or metal beads (“shot peening”).

In stark contrast to these processes, the Injector / Venturi blasting line operated by mirrorINOX is perfectly suited for the production of the BEADS product line with its particularly uniform, very homogeneous surfaces for the highest quality applications.

mirrorINOX is the choice to go for to bead blast your stainless steel surfaces –
here is what we can offer:

The mirrorINOX products of its bead blasting range are called BEADS.

The different variations of the BEADS finish are as follows:

BEADS  0                        -  glass beads with a very fine finish
BEADS  1                        -  glass beads with a fine finish
BEADS  3                        -  glass beads with a medium finish
BEADS  7                        -  glass beads with a coarse finish
BEADS  8                        -  glass cullets
BEADS  9                        -  ceramic beads

Grit-Polishing by mirrorINOX

When applying mechanical surface treatment processes such as grit-polishing, brush-polishing, satin grit-polishing, hairline grit-polishing, cross grit-polishing and others, various patterns and designs of polishing are achieved with the help of a variety of abrasive media, different machinery and machinery parameters.

Hereby, the desired results are defined by the customer's optical specifications, for example in architecture and other design applications, in which details such as the reflections but also the haptics of the surface play an extremely important role.

Since the stainless steel usually does not have a very attractive and often enough not reproducible surface quality coming from the mills and service centres, mirrorINOX processes their surface with very high-quality grit-polishing standards to lead you to a satisfactory result.

Applications

Whether it may be small quantities of material or larger projects in the fields of architecture, elevators, escalators, shop-fitting, exhibitions, ship- and yacht building or machinery engineering or many others, predominately based on stainless steel AISI 304 respectively AISI 316 for outdoors applications and in particular for façade construction, as well as using raw materials such as aluminium, titanium or brass - mirrorINOX always offers you the optimal solution, also for grit-polished surfaces. You can find some fascinating examples of applications here on our website.

Another highly sought after products are finishes with extremely low Ra values. These can go up to high-gloss surfaces (Ra value <0.1), which are required for the most demanding industrial applications, for example in container and machine construction for the pharmaceutical and food industry or in clean-room and medical technology. mirrorINOX meets here again the highest technical requirements for stainless steel surfaces and others.

How we grit-polish stainless steel

Many years of experience in grit-polishing, measurement of the roughness depth and the gloss of the surface, as well as the professional assessment of the visual impression are the base and success of mirrorINOX's controlled and precisely recorded production.

PVD-coating / TiN-coating bei mirrorINOX

The PVD / TiN-coating process is increasingly demanded by architects, product designers and a large number of other users.

Naturally, mirrorINOX being an expert when it comes to surface treatments, is focusing strongly on using this pvd process to predominantly coating stainless steel sheets and other having gained vast expertise with this technology.

The commonly used terms “PVD-coating”, “TiN-coating” or “titanium nitride coating” stand in principle for one and the same process and are used synonymously when it comes to coating of stainless sheets.

Stainless steel PVD-coating – the PVD-coating process explained

In contrast to alternative coatings, for example galvanic processes, PVD-coating / TiN-coating uses no toxic or environmentally harmful substances.

Additionally, the extremely thin layers of the coating are very natural in their metallic and lively appearance, which distinguishes them decisively from alternatives such as wet painting, powder coating or anodized finishes.

Therefore, the PVD-coating process clearly proves to be an excellent method to coat the substrates. By the vapor deposition, not only are physical and technical advantages created, such as an increase in hardness or improvement in corrosion resistance, but also an optically high-quality refinement of these substrates
is achieved when coated with the thinner layers.

In the case of stainless steel PVD, for example, the colored surface coatings obtained with the PVD technology do not only protect the substrate, but also create fascinating metallic and optically extremely attractive shades, which range from champagne, yellow gold and brass to rose gold and bronze to anthracite and black.

Those fascinating colours, in combination with various basic surfaces, give the stainless steel an exclusive appearance and create brilliant examples of applications in architecture and product design for both indoors and outdoors.

What is PVD?

PVD is the process of Physical Vapor Deposition. The PVD / TiN-coating of large areas (sheets) is carried out with the help of ARC evaporation,
in which the "target material" in the form of a solid is brought to evaporation by means of an arc so that it can later be applied to the sheet or workpiece.

By adapting suitable reactive gases, different temperatures and other machine parameters, the chemical combination of metal and non-metal achieves different colors on the surface of the sheets or workpieces.

PVD-coating or TiN-coating: What is the difference?

As mentioned earlier, the abbreviation PVD, which refers to the English term "Physical Vapor Deposition" and also the term “TiN”, the abbreviation which derives
from the chemical compound titanium nitride (a hard metallic material made of titanium and nitrogen, typically of a golden yellow color), both define the same process of physical vapor deposition, and denote the same group of vacuum-based coating processes or thin-layer technologies.

As such, we will gladly advise you about these and other technical details as well as the possibilities mirrorINOX is able to offer when it comes to the PVD process.
We promise to our utmost to not let you in the dark about the PVD services we offer to you as it is in our strong belief that transparency is a fundamental right
of any customer.

mirrorINOX – Whether titanium nitride coating or PVD coating:
Stainless steel is our core competence

Our specialist staff has been working intensively on this unique coating technology for two decades and are developing constantly new properties and designs
for potentially new applications and projects.

Our currently two PVD-coating lines are configured with the latest tailor-made, state-of-the-art technology. Combining both ensures outstanding results.

Green nanoINOX

nanoINOX® - The nano-coating by mirrorINOX

Regardless to the specific application, the question of how to protect and ultimately nano-coat the surfaces is becoming a more and more important issue. Although there have been various so-called nano-products around for a while already, there were always too many compromises for the customer to accept.

The now available nanoINOX® AFP/ ETC coating manufactured by mirrorINOX based on the latest SolGel technology with its Anti-Finger-Print (AFP) /
Easy-To-Clean (ETC) properties gives customers a highly effective and attractive solution which, in contrast to competing products, provides simply more benefits and consequently adds more function and value to their application.

The nano-coating produced by mirrorINOX

The nanoINOX® coating produced by mirrorINOX offers unique functions and has practically limitless design options, especially on stainless steel surfaces.

Not only is it possible to choose from a myriad of color tones, surface finishes and even create one`s own exclusive customized designs.

Furthermore, properties such as color, hardness, temperature stability, corrosion and chemical resistance, transparency or workability (formability) can be controlled and enhanced by embedding various elements into the layer of the coating.

One of the most requested properties of the nanoINOX® SolGel, along with the tremendously large variety of optical and design options, are the Easy-To-Clean (ETC), AntiFingerPrint (AFP) functions (Lotus leaf effect).

It can be used both for indoors and outdoors applications, protecting the surfaces against pollution and contamination, such as fingerprints, graffiti and many others, saving massively on cleaning and maintenance costs, performing excellently under weathering, keeping project and product clean, hygienic and visually attractive.

Additional, technical functions of the coating, such as antibacterial or electrically insulating properties are also possible to be built into the layer.

The areas of application for the nanoINOX® coatings are plentiful. For example, a nanoINOX® surface can be used for catering products, in elevators, yacht interiors or as facade panels.

In stark contrast to alternative coatings, for example galvanic processes, the nanoINOX® coating does not use or leave behind any toxic or environmentally harmful substances.

The nanoINOX® new technology guarantees a very precise and strictly controlled, color-uniform reproduction when coating stainless steel sheets, regardless of raw material batch-to-batch related variables.

The industries and their applications for our nano-coating

The groups of customers and the areas of applications where nanoINOX® surfaces are used, are just as diverse as the coatings themselves:

In architecture, whether for small applications or in large projects, in the shop fitting-, sanitary- and wellness-industry, in yacht- and shipbuilding, for silos and containers, plant and mechanical engineering, in aerospace, medical or automotive technologies, for household or electrical appliances, even in art projects,
the nanoINOX® coating by mirrorINOX proves to be the ideal material.

In all these fields, the nanoINOX® coating adds value to the product or to the application by increasing the attractiveness, service life, hygiene conditions, robustness and major reduction of cleaning and maintenance costs.

What is a nano-coating?

The application of nanostructures to surfaces is generally referred to as nano-coating. It makes the surfaces superhydrophobic, so that any liquids getting in contact with the surface will form droplets and run off (lotus effect) or superhydrophilic, meaning liquids that get onto the surface form a liquid film and run off. Consequently, the nano-coating seals the surfaces and makes them water and pollution repellent. A lotus effect is achieved, facilitating the cleaning procedures, reduces the number of cleaning cycles, saving massively costs and chemicals, which is also good for the environment.

The nanoINOX® coating is based on the SolGel process, which is one to most tried and tested nano-coating.

How we apply the nano-coating

mirrorINOX applies the nanoINOX® coating, based on the latest SolGel technology, onto the surfaces with the help of a multi-head rotary atomizer. Those are predominantly prepared and cleaned stainless steel sheets finishes.

After the applying, the surfaces will be treated by running through a conveyor furnace, reaching temperatures up to 250°C.

The range of the coatings with a thickness of usually 2 and 5 microns starts off with a transparent layer and can be complemented with colour pigments of a vast variety.

Fluid forming stainless steel by mirrorINOX

In the field of architecture, product design and other industries, new creative solutions are constantly being sought in order to create an attractive, exclusive and unique forming of different metal materials.

The fluid forming surfaces from mirrorINOX, also sometimes not quite correctly called "Hydroforming", "Hydroforming stainless steel" or "Hydroforming aluminum", are manufactured using a highly progressive, innovative and complex process of 3D fluid technology.

This forming technology sets new standards in the forming of metal and in the production of metallic structured surfaces, both in terms of aesthetics and design, as well as to the advantages relating to statics, acoustics and sun protection properties.

What is Fluid Forming?

With this technology, sheets are pressed with the help of a liquid under high pressure onto an individually manufactured tool. This processing is possible using an extremely powerful press, which was originally developed for forming processes in the automotive industry.

Where are fluid forming surfaces used?

The innovative and sustainable surfaces are used in architecture, for example as facade panels or ceiling and wall cladding in indoor and outdoor areas.

They can also be found more and more frequently in the fields of shop-fitting and exhibition-building, ship and yacht construction, but also for applications in product design and art.

In addition to their unique, visually attractive properties, the formed sheets have high strength and reduce the weight of the components through the use of thinner thicknesses.

mirrorINOX: Fluid Forming from aluminum to stainless steel

From the number of all already designed tools and the resulting structures in connection with the most diverse surface finishes based on stainless steel such as Super Mirror No. 8, BEADS, VIBES, SATIN, HAIRLINE, but also with alternative, cold-formable materials such as aluminum, copper, steel, titanium, etc., combined with colors and coatings such as PVD / TiN, nanoINOX® and others, mirrorINOX offers a unique and almost limitless number of combinations and design options.

Depending on the tool and material, a production of dimensions up to 4,000 x 2,000 mm is possible.

Of course, all this in the well-known mirrorINOX quality and delivery reliability.

As your competent partner for new solutions and designs, we support you in the realization of your drafts and ideas and together with you we want to push the limits of what was previously possible further and further.

Patterned Finishes by mirrorINOX

Most of us who are dealing with steel, stainless steel or other non-ferrous metals have an idea what the terms "rolling steel", "rolling metal sheets", "hot rolling" or "cold rolling" stand for.

It becomes more special when it comes to terms such as "pattern rolling", "design rolling", "structure rolling", "emboss rolling" or just "designing". With this special rolling manufacturing process, various metal surfaces can be refined and their properties can be changed and improved both technically and visually.

These types of products are of great interest to a large number of customers from most different fields: From architecture and design to industry such as mechanical engineering and many others.

Pattern rolling as a manufacturing process

For conventional rolling manufacturing processes such as steel rolling or rolling of metal sheets, plain and flat rolls are usually used. In contrast to that, pattern rolling is possible only by using individually designed, custom manufactured structured rolls, which make pattern rolling a rather specialized process.

A wide variety of structures and designs could be etched onto these rolls which are made of extremely hard special stainless steel. These structures are defined on the one hand by the technical requirements and parameters of the forming, embossing process (structure depth, working width, sheet thickness, material hardness and others) and on the other hand, of course, by the customer's design requirements.

Traditionally, the pattern rolling found its first applications in industry, namely in mechanical engineering. The rolling manufacturing process gives the sheets properties such as rigidity and a consequential weight saving by using thinner and lighter base material, robustness, slip improvement or slip resistance.

In the course of time, the metal sheets produced by using different pattern rolls became more and more popular in the field of architecture and design. In those applications, their advantageous properties such as optical flatness and scratch resistance came into play.

Thus, the metal surfaces of different alloys receive a technical-functional and visually high-quality added value through the rolling manufacturing process, making them an attractive and beneficial material in many markets.

What is pattern rolling process?

As already noted above, when design-rolling (sheets rolled on one side) or pattern rolling (sheets rolled on both sides), the rolling stock, i. e. the coils or sheets, is subjected to a rolling process with the aim of applying the structure of the respective roll(s) onto the sheets (on one or both sides).

The manufacturing technology is relatively uncomplicated and cost effective. The cold forming of a metal sheet or rather of its surface takes place mostly in coil, but it is also possible in sheet form. The selection of materials that can be rolled includes stainless steel, steel and other non-ferrous metals: even aluminium, brass or copper. All these materials can be improved in their surface quality and functional performance by pattern rolling.

Possible dimensions:

Length:            max. 6,000 mm
Width:              max. 1,500 mm
Thickness:      max. 2.0 mm

Pattern rolling by mirrorINOX

The numerous advantages, such as improved surface quality and resistance to scratches and dirt, optical flatness, high toughness, advanced technical and mechanical properties, as well as the visual appearance, which are achieved by rolling the sheet, clearly speak in favor of the patterned or pattern-rolled surfaces from mirrorINOX.

mirrorINOX also offers various rolled structures that are exclusively manufactured and distributed.

Patterned stainless steel by mirrorINOX - whether on one or two sides

mirrorINOX offers metal sheets rolled on one (patterned) and on both sides (pattern rolled) and possesses a high degree of specialized knowledge and many years of experience in this area.

While the sheets pattern rolled on one side meet requirements such as a higher-quality appearance and resistance to scratches, the properties of the sheets pattern rolled on both sides, such as even greater optical flatness and rigidity and interesting light reflections, are also highly appreciated.

Regardless of the intended use and the desired effect, mirrorINOX is happy to advise you and to find the ideal solution for you in this product group. As for many other special surfaces, mirrorINOX is the leading manufacturer and your consultant and supplier for the highest quality material even for the most difficult applications in the field of architecture, façades, ship and yacht building, shop construction or product design. Our product range therefore not only includes pattern rolled and designed sheets, but also ranges from nano-coating, PVD / TiN-coating, beadblasting, fluid forming and polishing to mirror polishing of stainless steel and other metals.

Stainless steel surface treatment

Stainless steel is a corrosion-resistant alloy steel thanks to its passive layer, which is used in very many areas of industry and architecture due to its remarkable properties.

In order to further improve products and applications made of stainless steel both in their visual appearance and in their functional properties, additional surface treatment is increasingly being applied. Brushed stainless steel is traditionally a very common and well-known example of this.

Visual surface treatments and improvements are of great importance, especially in architecture.

Colour, gloss, reflection and other design elements are playing an increasingly meaningful role in facades, roofs, wall and ceiling cladding, lifts, escalators, doors, counters and many other applications.

In product design and mechanical engineering, too, the visual appearance of stainless steel surfaces is of ever-increasing importance, making the product attractive and of high quality.

There is also a growing number of surface treatments that support and improve the functions of stainless steel or give stainless steels completely new properties.

For example, surface treatment can increase chemical resistance, weathering and corrosion resistance and electrical conductivity.

The application of antibacterial and easy-to-clean coatings, which reduce the maintenance effort and improve the hygienic condition of the stainless steel surface, also creates an even wider field of applications for stainless steel.

All about the surface of stainless steel

Although the material stainless steel has many positive characteristics such as easy availability, high resistance and good workability, it is only available in an extremely limited selection of surface variants from the stainless steel plants.

The "2B" (matt) and "BA" (shiny) finishes are the most common for the lower thicknesses. However, depending on the factory, material, thickness and batch, they are not of very high optical quality and the applications are visually very limited or can only be used technically.

In particular, the factory surfaces of hot-rolled or quarto sheets are not suitable for fabrication or use in the architectural or design sector.

mirrorINOX offers a variety of proven and newly developed surface treatment technologies to enhance the attractiveness and functionality of stainless steel. Even for the "extreme" surfaces of hot rolled or Quarto plates mirrorINOX is able to provide solutions.

Be it longitudinal or perpendicular grit-polishing, alternative grit polishing methods, beadblasting, mirror-polishing, PVD/TiN colour coating, nanoINOX® anti-fingerprint coating and other processes – mirrorINOX is the leading expert in stainless steel surface treatment!

Our tools and machines for stainless steel surface treatment

Our stainless steel surface treatment services at a glance

mirrorINOX offers the following processes of stainless steel surface treatment:

Polishing/Mirror polishing

Polishing or mirror polishing is a mechanical stainless steel surface treatment in which the surface of the primary material is first levelled and freed from defects by removal. Only then is the actual polishing/ mirror polishing carried out and brings the required/ mirror quality of the stainless steel surface.

mirrorINOX polishing lines and techniques are at the top of the world in terms of technological improvements, the dimensions of the polishable sheets and the surface quality of the mirror polish.

The largest ever mirror-polished sheet, measuring 14,973 x 3,347 x 16.0 mm and weighing 6,415 kg, was also produced by mirrorINOX at the end of 2018.

mirrorINOX combines a number of different polishing techniques and media with a great deal of experience to produce Mirror No. 7, Super Mirror No. 8, Marine Mirror No. 9. and Perfect Mirror No. 10® qualities on a wide range of grades such as AISI 430, AISI 304, AISI 316Ti, AISI 316L and even AISI 318LN ("Duplex") and more.

PVD coating

This surface technology makes it possible to coat sheets or parts with an extremely thin layer of approx. 0.2-0.3 my by evaporating a metal substance in a high vacuum using suitable gases and other parameters.

This so-called arc process, unlike other coatings such as galvanic processes, does not release any toxic or harmful substances. In addition, a very controlled, pre-material-independent coating in a choice of different colourtones is possible.

The PVD/TiN coatings have a natural metallic appearance and thus stand out from the bulk of other coatings.

nanoINOX® coating

This innovative nanoINOX® method of surface treatment, based on the SolGel process, enables unlimited design diversity and gives the material groundbreaking, functional properties such as AntiFingerPrint (AFP), Easy-To-Clean (ETC), antibacterial effect, change in electrical conductivity and others.

In our self-configured, state-of-the-art coating line, the sheets are pre-treated and cleaned according to the strictest criteria. Afterwards, the individually formulated coating medium is applied via a rotary atomiser and thus then brought to hardening in a 250°C continuous flow heater. This ensures high resistance and durability of the coating.

In addition to fascinating visual impressions, all our nanoINOX® coatings also offer excellent protection of the substrate against environmental influences such as corrosion, weathering, dirt, vandalism and graffiti thanks to the so-called "Lotus" or Easy-To-Clean effect, i.e. the surfaces do not get dirty as easily and are easier to clean.

It is also possible to apply a transparent protective coating to a wide variety of base surfaces, see more under "CLEAR nanoINOX®".

Compared to alternative materials, nanoINOX® surfaces improve highly the hygienic conditions and save customers cleaning costs, detergents and water, thus reducing costs and protecting not only your budget but also our environment.

Blasting

In many areas of industry, for example plant or mechanical engineering, different blasting processes are usually used to remove various irregularities (chips, scale, etc.) from stainless steel surfaces for later processing or to make the surface of the stainless steel more uniform and matt.

mirrorINOX goes further with its process (injector/venturi blasting) and, by blasting with different glass, ceramic or corundum media, creates decorative and functional surfaces on metal of the highest quality, which are uniformly matt, directionless, low-reflection or reflection-free and of very high homogeneous roughness.

These surfaces are created on stainless steel, aluminium, but also on non-ferrous metals such as brass or copper by bombarding them with a wide variety of blasting particles ranging from fine to coarse and using a wide range of parameters such as pressure, blasting angle and speed.

Here, sheets with dimensions of max. 2,000 mm (width) max. 6,000 mm (length) and max. 30 mm (thickness) can be surface treated.

Grit-Polishing

Grit-polishing and brush-polishing variants can be used to even out the rather unattractive factory surfaces and to remove minimal defects and imperfections such as lighter scratches that can be found on them. It is also possible to achieve specified roughness values (Ra) by grit-polishing the sheets for technical applications, such as tank or silo construction.

mirrorINOX creates a range of aesthetically attractive surfaces with a variety of grit-polishing and brus-polishing techniques.

Among other things, the use of abrasive belts with different grit sizes creates surfaces such as SATIN or HAIRLINE, both longitudinal and perpendicular

The polished finish of the stainless steel can be changed and adapted by using different grit sizes (K80, K100, K240, etc.) and settings on the machine.

Vibration polishing

A special type of grit-polishing is vibration polishing, also known as angel hair, rotation polishing or non-directional polishing.

With this optically very demanding surface treatment, a directionless, homogeneous and more or less matt surface of the stainless steel is achieved.

By measuring the roughness depth and the degree of gloss, as well as by expertly assessing the optical impression of the polished sheets, we record the production of each individual sheet very precisely.

The process used by mirrorINOX offers a wide range of designs and types of polishing design patterns combined with high capacities for even the most extensive projects.

Fluid Forming

The technology of fluidforming is only possible through the use of an enormously powerful press (120,000 t !!!), which was originally developed for forming processes in the automotive industry. It is used to form mirrorpolished, grit-polished, beadblasted or PVD / TiN and nanoINOX® coated metal surfaces.

In this way, stainless steel sheets and alternative materials such as steel, aluminium or non-ferrous metals are pressed under high pressure with a liquid onto a specially created tool and a variety of three-dimensional shapes and surface structures are produced.

You can find a first selection of structures on the page "Fluid Forming".

mirrorINOX also offers many other customised possibilities for which physics is a limit in a few cases, but almost never the creativity of the customer.

Pattern rolling

With this surface finishing technique, the stainless steel sheet is design- or pattern-rolled in a one- or even two-sided pattern rolling process.

These rolling processes improve technical properties such as robustness, rigidity and scratch resistance, as well as visual attributes such as optical flatness or reflection behaviour.

mirrorINOX offers in this area the traditional designs such as LEINEN, 5WL, 6WL or 7WL, but also, depending on the project size, new solutions created according to customer requirements.
