Try to choose the installation time before the bricklayer finishes, because the previous bricklayer and mason can trim and smooth well. The installed security door will have a protective film, or you can add another layer of protection yourself. If it is not a man-made collision, it will not cause harm.

First, the door frame of the security door should be closely connected with the wall and filled with expanded glue or cement or other fillers. If the gap is too big, it is better to add steel bars. If the door is not square or the size does not match the security door, chisel off the wall first. If the security door is installed before the ground treatment, be sure to ask the height of the workers after the ground treatment to avoid the situation that the ground is too high when installing.

Second, the door frame of the security door can be fixed to the wall with expansion bolts, or iron pieces can be buried in the hole when building the wall, and the door frame can be welded firmly when installing. No matter how the door frame is connected to the wall, there should be no less than 3 fixed points on each side, and the connection is firm. When installing the security door, it should be hung upright, temporarily fixed after the size is appropriate, corrected and adjusted, and then anchored.

Three, the gap between the door frame and the wall should be filled with cement or sealed with expansion agent, and covered with a special plastic cap to avoid noise from the air inlet. Because there is a gap, there will be wind entering, and the louder the wind, the louder the noise.
