Surface Treatment is normally requested for a metal part after fabrication as the purpose of anti-rust, good looking, or stability. There are many different Surface Treatment based on different material or functionality. Bascially what we usually applied are: Powder coating Liquid Painting Zinc plating Hot dipped galvanization Anodization Oxide Passivation Nitrid Ect...
Powder coating: Powder coating is normally used when the product is made from Steel, this is mainly used for anti-rust purpose. Liquid Painting: It is similar to powder coating, but in some certain industries like Vehicles, painting is normally used. Zinc Plating: Zinc plating is used for steel parts, silver or bluish colors are available. Hot Dipped Galvanization: Usually short as HDG, usually it is used for thick and heavy steel parts. It has much stronger anti-rust capability than zinc plating, but the surface is rough. Anodization: it is normally used for aluminum parts to avoid oxide. Different colors available. Oxide: it is usually used for small steel hardwares, black color. Passivation: it is usually used for stainless parts to make the stainless part more durable Nitride: it is a type of Heat treatment which is used to make the finished part Hard.
