Hygienic stainless steel sheet metal for the food industry
Hygienic, corrosion-resistant and cleanable stainless steel sheet metal work for the food industry — where accuracy and finishing are essential.
About this industry
- Stainless steel 304
- Stainless steel 316
- Food processing machinery
- Process equipment
- Conveyor guards
- Enclosures
For the food industry we supply stainless steel sheet metal parts and welded constructions with smooth, cleanable surfaces and carefully finished weld seams: conveyor guards, cover plates, enclosures and frames for process equipment. Stainless steel forms a hard, non-absorbent surface that resists chemical cleaning agents — provided the finish is right. Scratches, unevenness and weld residue make a surface harder to clean.
Cleanability starts in the design. Chamfered edges, rounded corners and as few horizontal surfaces as possible prevent food residue from collecting. We choose tolerances so that seams and gaps stay small. For enclosures we include access points, removable panels and condensate drainage at the engineering stage, so that installation and maintenance stay simple.

Laser welding produces narrow, clean seams with little spatter and minimal distortion. We then remove weld oxides, burrs, sharp edges and weld spatter, and passivate the stainless steel for corrosion resistance. Automated welding for series production is outsourced to a regular partner.
Which certification is required differs per customer, but regulations such as the European regulation on food contact materials (EU 1935/2004) often play a role. We document material choices and processes so that they can contribute to meeting them. If you need traceability of stainless steel grades and welding consumables for audits, please state this in your request.

Frequently asked questions
Why is stainless steel the preferred material in the food industry?
Stainless steel is corrosion-resistant and relatively easy to clean, which limits the growth of micro-organisms. It does not react with food and resists chemical cleaning agents.
Which surface finish is most suitable?
Often a smooth, finely ground to matt polished finish with a low roughness value. It prevents food residue from building up and makes cleaning easier. We match the finish to the product and the cleaning process.
How does custom work improve the cleanability of machine parts?
Custom work lets the design be tailored to ease of cleaning: minimising gaps and seams, avoiding sharp corners and keeping inspection and maintenance points easy to reach. This reduces the risk of contamination.
