There are many materials for hardware handles, and the surface treatment process of different materials is different. Take metal handles as an example. Common metal handles are made of iron, stainless steel and alloy.
1. The surface treatment of stainless steel is generally wire drawing or vibrating light, wire drawing will make the surface look textured, and vibrating light will make the surface look brighter.
2. The common surface treatment method of iron and alloy is chrome plating, nickel plating and color zinc plating. Electroplating can isolate the handle from the air and make the handle not easy to rust. Users can choose chrome-plated nickel-plated or color-plated zinc-plated handles according to their needs.
3. Zinc is an amphoteric metal, which can react with acidic substances as well as alkaline substances. Zinc will hardly change in dry air. In humid air, the surface of zinc will form a dense zinc carbonate film with moisture in the air.
The handle has different surface treatments because of different materials. We can also customize different surface treatments according to customer requirements.
