Surface Finishing Services
Precision surface treatments to meet functional and aesthetic requirements across industries
We offer a wide range of surface finishing services for metal components to enhance corrosion resistance, appearance, wear resistance, and functionality. Our services support various materials and comply with international standards.
Common Surface Finishes
Explore tailored solutions for your unique surface requirements.
Anodizing
Electrochemical process mainly for aluminum, improves corrosion resistance and allows coloring
Electroplating
Adds a metal coating (e.g., nickel, chrome, zinc) for appearance and protection
Sandblasting
Surface roughening or texturing using high-speed abrasive stream
Polishing
Mechanical or chemical polishing for a smooth, glossy finish
Black Oxide
Creates a black protective layer mainly for steel
Passivation
Used for stainless steel, removes surface contaminants and improves corrosion resistance
Powder Coating
Dry powder sprayed and cured for a durable, colored finish
Brushing
Creates directional satin finish, often used for aluminum/stainless steel
Application Guide
