Surface treatment

Pickling technique

The fine finish of the surface is not only made for clean optics but also for hygienic protection and quality safety.
Pickling removes impurities like tinder, oxide films, tarnish, extraneous rust and metallic and organic matters, pressed in the surface by mechanical treatment. Only clean and metallically unsoiled surface can develop the passive layer which protects the stainless steel from corrosion.

Pickling cabinet: 2,0 m x 2,3 m x 5,8 m
Manual spray pickling workplace:
7 m x 3,5 m, height 3 m

Blasting technique

Blasting allows a very gentle and material appropriate (aluminium and stainless steel) removal of impurities. Impurities are removed and a smooth, directionless and cloud-free surface is accomplished. Ceramic pearl blasting strain-hardens the surface and makes it more resistant to wear.
