Key principles.
Industry standard
Most common sheet metal finish. Tough, durable, color-flexible.
Type II/III
Aluminum sheet metal anodized. Decorative or hardcoat.
Steel sheet
Zinc plating for steel sheet corrosion resistance.
Hot-dip
Hot-dip galvanizing for outdoor structural sheet.
Custom colors
Wet painting for custom colors and specialty effects.
Aluminum, stainless
Mechanical brushing for aesthetic.
Matte
Bead blasting before anodize/paint for uniform texture.
Engraved or printed
Logo engraving or screen printing.
Restore corrosion
Citric acid passivation for stainless after fabrication.
FAQ
Tough, durable, color-flexible, no VOC, repeatable, recyclable overspray. Industry standard for sheet metal.
50-150 µm typical. Thicker for severe environments. Affect mating tolerances — account in design.
Pantone matching available. Sample approval before production lot.
Specify grain direction (parallel to long edge typical). Continuous grain across welded assemblies impossible — match where visible.
Powder coat 20+ year warranty. Galvanized coating for severe outdoor.
Pretreatment + coating typical. Phosphate or chromate before powder coat for adhesion.
