Surface finishing for aluminum and stainless steel.

Lasting impression – preparing test samples together on site

Structure and colour in aluminium

The BWB gives the aluminium the surface it deserves. For industrial design applications, this is a suitable surface texture and colour. BWB finishes aluminium components of all kinds with mechanical and chemical pretreatments and suitable colouring processes.

Mechanical surface finishing

Mechanical and chemical pre- and post-processing produce a wide variety of surface textures: from ground, to silk-matt, to polished surfaces. The process choice depends on the geometry of your part, the alloy, and the appearance you desire.

Colour anodising

Colour anodising creates a protective oxide layer that is coloured throughout. The resulting layer is abrasion-resistant and retains the metallic character of the component. Immerse yourself in the BWB Surface Technology world of colors.

Plasma polishing

Are you looking for the pure mirror shine? Then we recommend a conversion to chrome nickel steel with subsequent plasma polishing. During this surface finishing process, weld seams are cleaned, discolourations are removed and surfaces are polished - for the perfect shine
