Häufige Fragen
Why prime immediately after blasting?
A blasted steel surface oxidises within hours in humid air, which weakens paint adhesion. We blast and prime in sequence so the window never closes.
Can aluminium be sand blasted?
Yes with a suitable media, though it must be handled carefully because soft aluminium can embed abrasive. For cosmetic aluminium we use glass bead blasting instead.
Does blasting remove weld discolouration?
Yes, it removes heat tint and scale from welds, and we then passivate stainless to restore corrosion resistance.

Anodizing
Type II and Type III anodizing for aluminium: clear, black and colour finishes with improved corrosion and wear resistance, thickness from 5 to 50 µm.
Hard Anodizing
Type III hard anodizing builds a 25-50 µm ceramic-like oxide layer with up to 500 HV surface hardness for wear-critical aluminium parts.
Bead Blasting
Glass bead blasting for a uniform satin finish on metal and plastic parts. Hides tool marks, prepares surfaces for coating and gives a premium matte look.
Polishing
Mechanical polishing to mirror and optical finishes: Ra down to 0.05 µm for mould cavities, light guides, medical parts and decorative surfaces.
Powder Coating
Powder coating in RAL and Pantone colours: durable, thick and impact-resistant finish for sheet metal and fabrications, from 60 to 120 µm.
