Tongmen production process is more complex, the door for the door than the general treatment of some unique steps, which is one of the characteristics of copper doors.
In general, copper doors do not need to do too much color processing, just keep the original red yellow.
The interior of the copper door is a steel frame, and the outer cladding is a good copper panel profile.
Easy to bend shape, easy to crack the T2 copper belt is copper door panel profiles, in the use of copper doors more.
Although copper is anti-corrosion materials, but the copper door in the production often also for its further anti-corrosion treatment.
For example, first in the surface drawing, and then a number of surface cleaning, passivation, partition panel surface of the village and the contact with the corrosive material to maintain the original color of copper.
Followed by another two times the phosphating treatment, the formation of a protective film on the surface, which also after the spray paint, 1600 ℃ baking, natural cooling and other steps, a Tang finished copper door to the final completion.
As for the door of the steel skeleton, have been hot-dip galvanized, and then the steel structure welding, installation.
In addition, with other materials like the door, the copper door should be customized, the workers to determine the details of the scene after the investigation, and then go back according to the relevant data and drawings cut.
