Metal Surface Finishing Types: How To Choose The Right Treatment For Your Parts

Metal Surface Finishing Guide: Anti-Rust, Corrosion & Aesthetic Solutions For Custom Metal Parts

Many customers’ qualified processing parts fail final inspection due to inappropriate surface finishing, leading to delayed delivery and extra cost. As a full-process metal fabrication factory, Kaishi Hardware sorts all common metal surface treatment crafts to help buyers make correct selection according to product usage scenarios

Main Surface Finishing Services We Support

1. Powder Coating: thick coating layer, scratch resistance, multiple color options, widely used equipment housings, brackets

2. Electroplating (Zinc/Nickel/Chrome): excellent anti-rust performance, low cost for carbon steel stamping parts

3. Aluminum Anodizing: hard anodizing for wear resistance, decorative colored anodizing for electronic accessories

4. Polishing & Sandblasting: matte or mirror metal surface, remove processing burrs & welding traces

5. Passivation: improve stainless steel corrosion resistance without changing part size

Matching Craft Suggestions For Different Materials

- Carbon steel: zinc plating + powder coating (prevent rust in outdoor environment)

- 304/316 stainless steel: polishing / passivation (food, medical, marine equipment)

- Aluminum alloy: anodizing (lightweight electronic, new energy parts)

Our One-Stop Advantage: No Third-Party Surface Treatment

Most hardware factories outsource surface processing, causing inconsistent color & long lead time. Kaishi matches internal surface treatment workshop, all processing links finished in our factory, unified quality control, shorter delivery cycle.

How To Clear Mark Surface Treatment Demand On Drawings

When sending drawings for quotation & sampling, please clearly mark: surface craft type, coating thickness, color, environmental requirement (salt spray test hours). Clear requirements accelerate sample confirmation progress.

Kaishi Hardware, 18 years custom metal parts manufacturer, integrate laser cutting, stamping, deep drawing, CNC, welding and full surface finishing, own mold R&D team, accept drawings & samples for rapid prototyping.

If you don’t confirm which surface finishing fits your metal components, send your drawings and product application environment to our engineers, we provide professional matching suggestion free of charge.
