常见问题解答
Does grain direction matter?
It matters visually and functionally: grain must run consistently across adjacent panels, and on parts that slide, the brushing direction affects friction. We state the direction on the drawing.
Can brushed surfaces be anodized?
Yes, and the combination is very common on aluminium. The brushing shows through the anodic layer, producing a satin metal look that resists corrosion.
Can you match my existing finish?
Send a sample and we will match grain size and direction. Matching precisely across different suppliers is difficult, so we approve a sample before the batch.

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.
