How to choose a bronze door to be satisfied? What should I pay attention to when buying copper doors?

Select the anti-drilling lock. After the drill bit is drilled into the lock hole, the lock head will rotate synchronously with the drill bit when rotating, which can prevent the lock head from being damaged. The lock needs a three-way locking structure, with three hinges for a single door and six hinges for a double door. The door leaf and door frame are locked, even if the hinge is cut off, the door can't be opened.

2. The number of locks and pins on the doorman.

It is best to choose two locks and use two plungers to control the door, even if it can be destroyed, it will waste time. Generally speaking, a lock head can control three or four strips, so the door's anti-theft performance is very poor. Once the lock head is damaged, several cutting rods will lose their function at the same time.

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

Copper doors are divided into two types in structural design: closed and fence. No matter which one you choose, the lock is the main part of theft and damage, so the lock guard plate should be cold steel plate with a thickness greater than 2 mm and the height of the guard plate should not be less than 500 mm

4. Look at the quality of the process

The choice of copper door material is fundamental and the quality of manufacturing process is the key. Pay special attention to check whether there are welding defects such as open welding, incomplete welding, missing welding and slag inclusion. See whether the door leaf and the door frame are closely matched, whether the gaps are uniform and consistent, whether they are flexible to open, whether the joints are foraging, and whether the paint electroplating is uniform, firm and smooth.

5. Choose from the design.

Copper doors on the market are divided into three types: luxury, mid-range and ordinary. The luxury panel is made of stainless steel plate, the main frame is made of stainless steel square tube, and the decorative fence is made of stainless steel profile; The mid-range type generally adopts the combination form of Fiona Fang steel and ornamental design; Common ones are square steel tube, round steel and flat steel (16×4 mm). Users can choose their favorite type according to their own situation.

In addition, when installing copper doors, it is required to fix them with expansion bolts and weld them by electric welding, with no less than 8 fixing points and 4 on one side. In terms of maintenance, it is advisable to oil the door shaft and plunger every 3-6 months to make them open flexibly, but don't oil the lock head to avoid dust affecting the performance of the door lock.
