1. Production process
The manufacturing process of bronze doors is more complicated, and there are some more unique steps in the treatment of doors than ordinary doors, which is also one of the characteristics of bronze doors. Generally speaking, the bronze door does not need to do too much color processing, just keep the original red yellow. The inside of the copper door is a steel frame, and the outside is covered with processed copper panel profiles. The T2 copper strip, which is easy to bend and shape, and not easy to crack, is the profile of the copper door panel, which is often used in copper doors. Although copper is an anti-corrosion material, the copper door is often treated with further anti-corrosion treatment during the production. For example, the surface is drawn first, and then the surface is cleaned and passivated multiple times to cut off the contact between the surface of the panel profile and the corrosive material, and maintain the original color of copper. Next, no less than two phosphating treatments are carried out to form a protective film on the surface. After that, it is necessary to go through the steps of spraying protective paint, baking at 1600 degrees Celsius, and natural cooling. The steel frame inside the door is hot-dip galvanized, and then the copper structure is welded and installed. In addition, like doors made of other materials, copper doors should also be customized. Workers will check on the site to determine the details and then go back to blank the materials according to relevant data and drawings.
2. Classification
Copper doors can be divided into imitation copper doors, real copper doors, copper clad doors, villa copper doors, etc. According to the place of use, there are two types: indoor copper doors and outdoor copper doors.
According to the type of copper, it can be divided into: brass (copper-zinc alloy) door, bronze (copper-tin alloy) door, cupronickel (copper-nickel alloy) door, and copper door.
3. Features
There are many performance characteristics of the bronze door, the most prominent is its appearance. The reason why the bronze door is not bad for a hundred years is also because of its strong temperament and timelessness. Copper is inherently warm, corrosion-resistant, anti-bacterial and anti-oxidant. It is not easy to be damaged. It has a longer lifespan than wood. Compared with bricks and tiles, copper doors are more resistant to ageing. It also has excellent appearance, gorgeous colors, solidity and stability without losing elegance, and it contains new ideas in the ancient. . Created by precision craftsmanship, sincere ingenuity, and beautiful in all shapes. Inheriting the elegance of traditional architecture without losing the sturdiness of the material, waterproof and anti-corrosion, the perfect combination of exquisite copper craftsmanship and modern technology can make a limited space volatilize unlimited tolerance.
