The production process of the copper door is more complicated, and the processing of the door will have some more unique steps than the general door, which is also one of the characteristics of the copper door.

Generally speaking, copper doors do not need too much color treatment, just keep the original red and yellow.

The inside of the copper door is a steel structure skeleton, and the outside is covered with processed copper panel profiles.

The T2 copper tape, which is easy to bend and shape and not easy to crack, is the profile of the copper door panel, and is widely used in copper doors.

Although copper is an anti-corrosion material, copper doors are often subjected to further anti-corrosion treatment during the production.

For example, the surface is first drawn, and then the surface is cleaned and passivated several times to cut off the contact between the surface layer of the panel-type village and the corrosive material, and maintain the original color of the copper.

Next, no less than two phosphating treatments are carried out to form a protective film on the surface. After that, steps such as spraying protective paint, baking at 1600°C, and natural cooling are required to complete a finished copper door.

As for the steel frame in the door, it has been hot-dip galvanized, and then the steel structure is welded and installed.

In addition, like doors made of other materials, copper doors should also be customized. After the workers survey the site to determine the detailed dimensions, they will go back and cut materials according to the relevant data and drawings.
