How to achieve the best effect of security door installation

How to install the security door will achieve the best results? The following eight steps will teach you how to better achieve the best effect of the security door.

The installation time was chosen before the bricklayers were completed. Many people consider that there are many things to be handled before the completion of the basic decoration. They fear that the security door has been broken. They do not know that because the security door installation is generally a process that needs to be replaced, it will destroy the wall of the doorway. If it was installed before, bricklayers, Oil workers can take a good rest. The security door installed will have a protective film, or you can add a layer of protection yourself. If it is not deliberately bumped, it will not cause damage.

After the security door is delivered, be sure to open the cardboard box for inspection and confirm that there is no problem before installing it. I complained a lot about the security door on the upstairs and downstairs neighbors, mainly lacquer flaws. Some of the more prominent are the bumps on the door frame and the door leaf. This may be due to long-distance transportation. It must be repaired or replaced before installation. .

When installing the security door, if the door hole is not square or the size and the security door cannot be closed, the wall should be flattened first. If the anti-theft door is installed before the ground is processed, be sure to ask what the height of the worker's floor is after processing, and send the data back to the door factory so as to avoid the situation that the ground is too high during installation. Anti-theft door frames and walls should be closely connected, filled with polyurethane (expandable rubber) or cement, if the gap is large, it is best to add steel.

The door frame of the security door can be fixed with expansion bolts and walls, or iron pieces can be embedded in the opening at the time of masonry wall construction, and welded to the door frame connection pieces during installation. No matter which connection method is used for the door frame and the wall, each side should not be less than 3 anchorage points, and it should be firmly connected. When installing the anti-theft door, it should be straightened and lifted. After the size is appropriate, temporarily fix it, correct and adjust it, and then connect and anchor it.

Anchor gaps should be sealed with swelling agent and covered with special plastic caps. If there is a gap, if you can enter the wind, if the wind is big and strange sounds, it will be terrible.

After installing the security door, it is necessary to check the keys, invoices, after-sales orders, and other accessories and materials, and there should be no less keys. A good security door should be easily and flexibly opened with a key; the door should be flexible and free from jams, abnormal sounds, etc. during the opening of 90 degrees.

Door leaf and door frame are equipped with anti-theft chain, it is necessary to check whether the installation of the anti-theft chain is firm and whether the handle is flexible and firm.

Now security doors basically provide renovation keys, you can give them one, keep one for yourself. After the hard decoration is basically completed, the decoration key is recovered, and then the official key is used to open the door. The decoration key is invalid. However, to be on the safe side, it is still necessary to test whether it really fails.
