After installing the security door, how much is left in the door

Yes, when the time comes, just fill the cement on the edge of the door frame, I don't know what to ask, I install it professionally.

After the installation of the anti-theft door, there will be gaps around the upper and lower left and right, because the current anti-theft door material is not as thick as before, so do not fill the gap with cement, if it is not good, the left and right door frames are deformed, the threshold below is bulging, and the good door is directly wasted.

There is no standard for Xiaotian unlocking in Qujiang District, Quzhou City, but you can check by yourself, whether there are scratches and dents on the door, whether the lock insurance is opened smoothly, whether the door will automatically open or close automatically in the half-open state, whether there is any abnormal noise, and whether the door frame is loose.

As long as it is firmly fixed, fill the inside with styrofoam, and the outside needs to be smoothed with cement and sand.
