Jinan opposite copper door is also called opposite door. Opposite copper door refers to the door of two door leaves, which can be opened on both sides. The size of both sides is the same. Generally, when the door opening is wide, it is designed to open copper doors in pairs for convenience and beauty. One door leaf is equipped with a lock, and the other door leaf is equipped with a false lock and bolt. The methods for Jinan copper door manufacturers to select split copper doors are as follows:

1、检查门锁、性能及结构

1. Check the door lock, performance and structure

选择防钻锁头，钻头钻进锁孔后，旋转时锁头会跟随钻头同步旋转，可起到锁头不被破坏的作用。锁具要求三方位锁闭结构，单开门3个合页，双开门6个合页，门扇与门框加暗锁，即使合页被錾掉，门也打不开。

The anti drilling lock is selected. After the drill bit is drilled into the lock hole, the lock will rotate synchronously with the drill bit when it rotates, so that the lock will not be damaged. The lock requires three-way locking structure, three hinges for single door opening, six hinges for double door opening, and concealed lock for door leaf and door frame. Even if the hinge is chiseled off, the door cannot be opened.

2、看门上锁头数量和插杆数量

2. Number of lock heads and inserting rods on the door

选择2个锁头各控制2个插杆的门，即使能被破坏，也会拖延时间。一般来讲，一个锁头可控制34根插杆，这样的门防盗性能较差，一旦锁头被损坏，几根插杆同时失去作用。

Choose two locks to control the door of two inserting bars, even if it can be damaged, it will delay the time. Generally speaking, a lock can control 3 to 4 inserting bars. This kind of door has poor anti-theft performance. Once the lock is damaged, several inserting bars will lose their function at the same time.

3、看锁具周围加强板的厚度和面积

3. Look at the thickness and area of the reinforcing plate around the lock

铜门从结构设计上分封闭式和栅栏式两种，不论选择哪一种，锁具是盗窃破坏的主要部位，所以锁具护心板应是厚度超过2毫米的冷钢板，护心板的高度不小于500毫米。

The structural design of copper door can be divided into enclosed type and fence type. No matter which one is selected, the lock is the main part of theft and damage. Therefore, the core plate of the lock should be cold steel plate with a thickness of more than 2mm, and the height of the core plate should not be less than 500mm.

4、看工艺质量如何

4. It depends on the quality of the process

铜门材料选择是根本，制作工艺质量是关键。山东铜门厂家提醒大家应注重检查有无焊接缺陷，诸如开焊、未焊、漏焊、夹渣等现象。看门扇与门框的配合是否密实，间隙是否 均匀一致，开启是否灵活，所有接头是否觅食，油漆电镀是否均匀牢固、光滑等。

The choice of copper door material is fundamental, and the quality of manufacturing process is the key. Shandong copper door manufacturers should pay attention to check whether there are welding defects, such as open welding, no welding, missing welding, slag inclusion and so on. Check whether the door leaf and door frame match tightly, whether the gap is uniform, whether the opening is flexible, whether all joints feed, whether the paint electroplating is uniform, firm and smooth, etc.
