1. Manufacturing process
The production process of copper door is more complex, and the processing of the door will be more specific than the general door, which is one of the characteristics of the copper door. Generally speaking, copper doors do not need to do too much color processing, just keep the original red yellow. The inner part of the copper door is a steel structure framework, and the outer part is coated with the processed copper panel profile. T2 copper strip, which is easy to bend and shape and not easy to crack, is the profile of copper door panel, which is widely used in copper door. Although copper is a kind of anticorrosive material, it will be further treated in the production of copper door. For example, wire drawing is carried out on the surface first, and then the surface is cleaned and passivated for many times to isolate the contact between the surface layer of panel profile and corrosive materials, and maintain the original color of copper. The next step is Phosphating for at least two times to form a protective film on the surface. After that, it has to go through the steps of spraying protective paint, baking at 1600 ℃ and natural cooling, etc., and a copper door can be finally completed. The steel framework inside the door is hot-dip galvanized, and then the copper structure is welded and installed. In addition, as with other materials, the copper door should be customized. After the workers have determined the detail size through field investigation, they can go back to the site to cut materials according to the relevant data and drawings.
2. Classification
Copper doors can be divided into imitation copper doors, real copper doors, copper clad doors, villas and so on. According to the place of use, it is also divided into two types: indoor copper door and outdoor copper door.
According to the type of copper can be divided into: brass (copper zinc alloy) door, bronze (copper tin alloy) door, white copper (copper nickel alloy) door, purple copper door.
3. Features
There are many performance characteristics of the copper door, the most prominent is its appearance characteristics. The reason why the copper door has not declined for a hundred years is also because of its rich temperament and never out of date. Copper is warm, corrosion-resistant, anti-bacterial and anti-oxidation. It is not easy to be damaged. It is longer than wood. Compared with brick and tile, the copper door is more age-resistant. Moreover, it has outstanding style, gorgeous color, thick and steady without losing elegance. It contains new ideas in the ancient and colorful. It is made by Seiko, with sincere ingenuity and exquisite craftsmanship. Inheriting the elegance of traditional architecture, but also without losing the firmness of material, waterproof and anticorrosion, the perfect combination of exquisite copper technology and modern technology can make the limited space volatilize infinite bearing.
