Anodized Aluminum Dark Bronze and Chrome Powder Coat
Specify anodized aluminum dark bronze using class, film thickness, and sealed color chips after abrasive blasting. For bright mirror aesthetics, we powder coat custom finishes on sheet enclosures instead of costly chrome plating. While unsuitable for sliding wear, this dry finish avoids hazardous tanks. See our metal finishes chart for detailed coating callouts.
Zinc Plating for Small Batch Steel Parts
Zinc plating is an economical sacrificial barrier for small batch steel parts requiring fast delivery. Simple rack tooling eliminates setup costs, and minimum lot pricing keeps initial runs affordable while higher volumes reduce piece rates. Specify clear, yellow, or black chromate passivates along with hydrogen embrittlement relief baking. Compare zinc plating types before selecting your chemistry.
