Welding: weld various shaped accessories, so that the door body is basically formed
Surface treatment: the blank of the vault door is polished by some meticulous processes, and then the surface is sprayed with plastic. Because the surface is still covered with rust spots and oil stains, phosphating treatment is required to achieve the purpose of degreasing and rust removal, and polishing is smooth. After ZUI, high-temperature electrostatic spraying treatment is carried out, and the surface is painted.
