Food industry: stainless steel for food-safe use

In general, stainless steel is nowadays used in many areas of architecture, industry and everyday life and it is impossible to imagine life without it.

Stainless steel materials have also taken on an increasingly important role in the food industry.

We would to explain this in a little more detail in the following article:

Why is stainless steel so suitable for the food industry?

In the past, wood, glass, copper, brass, steel and later also plastics were traditionally the materials used for the production, processing, storage, transport, presentation and consumption of various foodstuffs.

While these traditional materials still had many limitations, with the introduction of stainless steel it quickly became clear that its properties offered many advantages such as corrosion resistance, durability, availability, workability, sustainability and recyclability.

The protective, smooth and very stable chromium oxide layer not only provides a high level of corrosion protection, it also makes the material easy to clean and resistant even to aggressive media such as fruit- and other acids, as well as cleaning agents.

Bacteria, fungi or germs therefore have no surface to attack and this leads to a very high standard of hygiene.

Stainless steel can be processed and worked excellently and its good formability and weldability contribute to the versatile applications and the problem-free use of stainless steel.

Furthermore, stainless steel can gain additional functionality through the right treatment and processing of its surface. For example, by polishing to achieve good Ra values or by rolled-in or fluid-formed surface textures and structures, which can prevent or reduce the adhesion of the food sticking. This increases the flow of goods in production and packaging processes, improves productivity and reduces unnecessary and costly shut downs or stand-stills.

Likewise, these and other surface treatments contribute to making the visual appearance of stainless steel more attractive, which is a great gain for use in the food industry, but especially in the gastronomy, catering industry, food wholesalers and retailers, but also at home in the private, daily use.

Stainless steel thus combines functionality and design and fulfils even the highest requirements in both areas.

Which stainless steel is EU-compliant and approved for the food industry?

The requirements for the materials, used in the food industry and intended to come into contact with food, are defined by EU Regulation 1935/2004/EC.

This stipulates that they must not contain or release into the food any harmful substances that endanger human health. At European level, it is very well documented that stainless steel fulfils this requirement also.
