Preguntas frecuentes
What thickness do I need?
The standard is 8 to 12 µm, which gives good protection economically. For harsh environments we increase thickness and add a sealer to extend salt spray performance.
Is hydrogen embrittlement a risk?
It can be for high-strength steels above 1,000 MPa, so those parts are baked immediately after plating. We flag it whenever the material specification requires it.
Can plated parts still be welded?
Welding should be done before plating because zinc vaporises and contaminates the weld pool. We always plan the sequence with plating last.

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.
Sand Blasting
Sand blasting for surface cleaning, descaling and roughening. Removes rust, scale, old coating and oxide before welding, painting or bonding.
Polishing
Mechanical polishing to mirror and optical finishes: Ra down to 0.05 µm for mould cavities, light guides, medical parts and decorative surfaces.
