Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.
Standard
This is our standard finish. Parts as delivered as cut and bent, no additional treatment applied. Sharp edges are broken and deburred for safe handling.
Bead blasted
Parts are bead blasted with glass beads which results in a grainy texture. Sharp edges are broken and deburred for safe handling.
Brushed
Parts are manually brushed with grit #180 after cutting and bending. Sharp edges are broken and deburred for safe handling. Ideal to reduce the surface roughness of a part.
Brused + Anodized type II
Parts are dipped in an anodizing bath (type II) after manual brushing. Ideal for increasing the corrosion resistance of the part. Ideal for increasing the corrosion resistance of the part. Sharp edges are broken and deburred for safe handling.
Bead blasted + Anodized type II
Parts are dipped in an anodizing bath (type II) after bead blasting. Ideal for increasing the corrosion resistance of the part. Sharp edges are broken and deburred for safe handling.
Anodized type III (Hardcoat)
Parts dipped in an anodizing (type III) bath directly after fabrication. Ideal to improve corrosion and wear resistance of components. Sharp edges are broken and deburred for safe handling.
Powder coated
Powder coating layer is applied directly after fabrication. Sharp edges are broken and deburred for safe handling.
Black oxide
Parts are dipped in a black oxide bath after fabrication. Ideal to improve improve corrosion resistance and minimize light reflection in steel components. Sharp edges are broken and deburred for safe handling.
Chromate conversion coating
Parts are dipped in an alodine bath directly after fabrication. Ideal to increase the corrosion resistance of the part while maintaining its conductive properties. RoHS compliant. Sharp edges are broken and deburred for safe handling.
