1. Manufacturing Technology of Tongmen in Shandong Province

　　铜门的制作工艺是较为复杂的，对于门的处理比一般的门会多出一些特有的步骤，这也是铜门的特色之一。一般来说，铜门都不需作过多的色彩处理，只需保持原有的赤黄色。铜门的内部为钢结构骨架，外部包覆加工好的铜面板型材。易折弯塑形、不易开裂的T2紫铜带是铜门面板的型材，在铜门中运用较多。铜虽然属于防腐材料，但铜门在制作中往往还会对其做进一步的防腐处理。比如，先在表面拉丝，然后进行多次表面清洗、钝化，隔断面板型材表层与腐蚀材料的接触，保持铜原有的颜色。接下来再进行不少于两次的磷化处理，在表面形成一层保护膜，这之后还要经过喷保护漆、1600摄氏度烘烤、自然冷却等步骤，一樘铜门才能较终完成。而门内部的钢骨架都进行了热镀锌处理，然后将铜结构焊接、安装。另外，与其他材质的门一样，铜门也要定制，工人现场勘查确定细部尺寸后，再回去根据相关数据与图纸下料。

　　The manufacturing process of the copper door is more complex, and there are more unique steps to deal with the door than the general door club, which is also 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 covered with the processed copper face plate profiles. T2 copper strip, which is easy to bend, shape and crack, is the profile of copper door panel, and is widely used in copper door. Although copper is a kind of anticorrosive material, it is often further treated in the manufacture of copper doors. For example, first drawing on the surface, then cleaning and passivating the surface for many times, the contact between the surface of the partition plate profile and the corrosive material, to 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, a diaphragm door can be finished by spraying protective paint, baking at 1600 degrees Celsius and natural cooling. The steel skeleton inside the door is hot galvanized, and then the copper structure is welded and installed. In addition, like other material doors, copper doors should be customized. After the worker's on-site investigation determines the detail size, he will go back and cut materials according to the relevant data and drawings.

　　铜门可以分为仿铜门、真铜门、覆铜门、别墅铜门等。根据使用场所还分为两种：室内铜门、室外铜门。

　　Copper doors can be divided into imitation copper doors, real copper doors, copper-clad doors, villas copper doors and so on. According to the place of use, there are also two kinds: indoor copper door and outdoor copper door.

　　根据铜的种类可分为：黄铜（铜锌合金）门、青铜（铜锡合金）门、白铜（铜镍合金）门、紫铜门。

　　According to the types of copper can be divided into: brass (copper-zinc alloy) door, bronze (copper-tin alloy) door, white copper (copper-nickel alloy) door, copper door.

　　铜门的性能特点非常多，较突出的就是其外观特色，铜门之所以百年不衰，也是因为它的气质浑厚，永不过时。铜本性温润，耐腐蚀，抗氧化，不易受损，寿长于木材，较之砖瓦，铜门更耐岁，而且风姿，色调绚丽，浑厚沉稳中不失风雅，苍古盎然中蕴涵新意。通过精工打造，匠心诚厚，诸形工美。承传统建筑之典雅，又不失材质的坚固，且防水，防腐，将精湛的铜工艺与现代科技结合，可令有限的空间挥发无限的气度。

　　The performance characteristics of copper doors are very many. The most prominent feature is its appearance. The reason why copper doors are not fading for a hundred years is also because of its strong temperament and never outdated. Copper is mild in nature, corrosion-resistant, anti-bacterial and anti-oxidant, not easy to damage, longevity than wood, more durable than bricks and tiles, copper door, and excellent style, brilliant tone, thick and stable without losing elegance, ancient and full of new meaning. Through fine craftsmanship, ingenuity, all kinds of artistic beauty. With the elegance of traditional architecture, and without losing its solid material, waterproof and anti-corrosion, the perfect combination of exquisite copper technology and modern science and technology can make the limited space volatile infinite atmosphere.
