Surface finishing
Surface treatment finishing services for durability, aesthetic quality, and superior corrosion resistance.
Surface finishing
Our Surface Finishing services offer comprehensive treatments engineered to enhance durability, corrosion resistance, and visual elegance across diverse industrial substrates. From military-grade hard anodizing to automated powder coating, we ensure superior surface integrity.
Our modern finishing line includes automated multi-stage chemical pretreatment, electroless nickel plating, bead blasting, and high-temperature electrostatic powder curing for flawless adhesion.
Every finished lot is validated via ASTM B117 salt spray testing and non-destructive eddy-current thickness measurement, delivering certified longevity in harsh industrial environments.
Color & Hard Anodizing
Decorative color anodizing and hard-coat anodizing reaching 500 HV surface hardness.

Frequently asked questions
Standard Type II anodizing produces 8–15 µm coatings primarily for aesthetics. Type III Hard-coat is processed at near-freezing temperatures producing 30–50 µm layers with 450–500 HV hardness for extreme wear resistance.
