Due to the price and beautiful workmanship, popular consumers prefer imitation copper doors, compound copper doors and copper plated doors. But the life span and workmanship of pure copper can only be compared with that of pure copper. Therefore, upper consumers prefer pure copper doors with fine workmanship. Product quality and service life are naturally where copper door manufacturers spend more energy. Even slightly adjusted according to the climate characteristics.

铜门中如何区分复铜门、镀铜门、仿真铜门、铜铝门、仿铜门这六大类。

How to distinguish six categories of copper doors: compound copper doors, copper plated doors, simulated copper doors, copper aluminum doors and imitation copper doors.

简而言之，铜皮结构是纯铜门、复铜门、镀铜门都有的，但龙骨结构强度不一。板材同样是1.0mm，真铜门和复铜门相差0,15mm。它们大的区别是'：复铜门的组成部分是0.85mm的锌合金粘上一层0.15mm的铜箔;复铜门在不锈钢或锌合金板上镀上一层铜箔。仿真铜门、仿铜门、铜铝门三类是普通的铁质材料的铁门工艺。铜铝门主要是铝型材上仿铜漆，只是用了仿铜油漆。

In short, the copper skin structure is pure copper door, compound copper door and copper plated door, but the strength of keel structure is different. The plate is also 1.0mm, and the difference between real copper door and compound copper door is 0,15mm. The big difference between them is': the component of the compound copper door is 0.85mm zinc alloy bonded with a layer of 0.15mm copper foil; The compound copper door is plated with a layer of copper foil on the stainless steel or zinc alloy plate. Imitation copper door, imitation copper door and copper aluminum door are common iron door processes made of iron materials. Copper aluminum doors are mainly made of imitation copper paint on aluminum profiles, but imitation copper paint is used.

铜门的纯铜门，复铜门，镀铜门三类的工艺处理过程：

Three kinds of process treatment processes of pure copper door, compound copper door and copper plated door of copper door:

一、处理工艺的过程：①除油、锈、氧化皮;②水洗;③酸洗抛光;④水洗;⑤中和;⑥水洗;⑦着色处理;⑧水洗;⑨干燥及其它后处理。

1、 Treatment process: ① remove oil, rust and scale; ② Water washing; ③ Pickling and polishing; ④ Water washing; ⑤ Neutralization; ⑥ Water washing; ⑦ Coloring treatment; ⑧ Water washing; ⑨ Drying and other post-treatment.

二、酸洗抛光。用铜材酸洗进行抛光液处理。黄铜表面光泽提高。

2、 Pickling and polishing. Use copper pickling for polishing solution treatment. The surface gloss of brass is improved.

三、工作液中放入工件，黄铜表面生成黑青色。工件重复浸泡，变色层厚度会增加，效果令人满意。

3、 When the workpiece is put into the working fluid, the black cyan color is generated on the brass surface. If the workpiece is soaked repeatedly, the thickness of discoloration layer will increase, and the effect is satisfactory.

四、上述步骤处理后，经砂纸摩擦，可达到古铜色的效果。

4、 After the above steps, the effect of bronze color can be achieved by sandpaper friction.
