铜大门内部为钢结构框架，外包加工铜面板型材。
The inner part of the door is a steel frame, which is made of copper face plate.

为院外檐铜门楼，形体高大，雍容华贵，而作为普通公寓楼的户门虽然体型稍小，但同样富贵气派，品味却不凡。现代化铜拉门的色彩可做到近十种。山东铜门内部为钢结构框架，外包加工铜面板型材。容易弯曲、塑性强、不易开裂的T2紫铜带是铜门板非常好的型材，在铜门中应用较多。

尽管铜属于防腐蚀材料，但山东铜门在制造时往往还要对其进行进一步的防腐处理。例如，先在表面拉丝，然后多次进行表面清洁、钝化，将面板表面隔开与腐蚀材料的接触，保持铜的原有颜色。下一步要进行两次以上的磷化处理，在表面形成一层保护膜，在此之后，还要经过一道喷保护漆、1600度烘烤、自然冷却等步骤，完成一道成品铜门。关于门内的钢架均经过热镀锌处理，再焊接、安装铜结构。和其它材料一样，铜门也要定制，工人现场勘察确定细部尺寸后，再回回根据有关数据和图形进行下料，然后上门安装。
Although copper is an anti-corrosion material, it is often manufactured with further anti-corrosion treatment. For example, first in the surface drawing, and then repeated surface cleaning, passivation, will be separated from the surface of the panel and corrosion material contact, to maintain the original color of copper. The next step is to have more than two phosphating treatments to form a protective film on the surface. After that, a spray of protective paint, 1600-degree baking, Natural Cooling and other steps are required to complete a finished copper door. The steel frames inside the doors are treated with hot dip galvanizing, and then welded and installed with copper construction. Like other materials, the copper door is also custom-made, after the worker inspects the site to determine the detail size, then returns according to the related data and the graph carries on the blanking, then goes to the door to install.

铜是一种极为稳定的金属，其耐腐蚀性能极高，只要按常规方法处理就行。虽然铜的门自然防腐，但是遇到大量的硫和硫化物，还是容易发生化学变化。因此，如果在室外使用铜门，如别墅的大门等，要把它包裹在门的外框内，以防雨雪的侵袭，防止降水中的硫化物腐蚀。
Copper is a very stable metal, its corrosion resistance is very high, as long as the conventional treatment on the line. Although copper doors are naturally corrosion resistant, they are prone to chemical reaction when exposed to large amounts of sulfur and sulfides. Therefore, if the outdoor use of copper doors, such as villa doors, it should be wrapped in the outer frame of the door, to prevent rain and snow attack, to prevent precipitation of sulfide corrosion.

从实用性上来说， 山东铜门比普通门更耐用，不但没有变形、开裂的问题，而且配有高科技的配锁，防盗性能更好，使用寿命更长。
From the practical point of view, copper door than Potongmun more durable, not only no deformation, cracking problems, but also equipped with high-tech lock, anti-theft performance better, longer service life.
