Part 1: Handle
The handle is also called the door handle, and the most popular one is made of zinc alloy. Because of the excellent metal properties of zinc alloy, it can be made into many different shapes and colors. In addition to the quality of the handle, the more important thing is the production process. Special attention should be paid to the electroplating process. A good electroplating process needs to be polished in multiple layers to ensure that the surface of the handle is smooth. The internal metal is not corroded and oxidized. The electroplating process and the materials used are one of the important criteria to measure the quality of the handle of the handle.
