To install a metal door, you must prepare the following tools and accessories:
- Level, tape measure.
- A hammer drill or drill with a hammer drill function, drill bits for concrete, with a diameter equal to the diameter of the expansion screws (anchors) supplied with the door. This is usually 8 to 12 mm.
- Locksmith's hammer.
- A set of keys for threaded connections - hinges, lock. The key is the head. For screwing in spacer screws.
- A can of polyurethane foam.

Metal door installation sequence
Work begins with measurements of the opening, the choice of the door. Doors are produced in standardized sizes - 80, 90,100. 120 cm. wide and 2 m high. Depending on the width of the opening in the room, the door is also selected.
After purchasing and unpacking, they are inserted into the doorway and fixed on all sides with wooden wedges. With the help of a building level, the box is leveled by adjusting with wooden wedges. Then they try to close the door carefully - open it. It should fit freely into the box, and not have distortions. It is necessary to carefully check the gaps between the frame and the door. They should be the same around the entire perimeter.
If the gap is different, you can adjust it with hinges. To do this, they need to be slightly unscrewed and the door adjusted to the required values. Also, it should not spontaneously open or close. This also needs to be paid attention to, and adjusted if necessary. Then, through the internal holes in the box, holes are drilled at the ends of the wall with a perforator to install spacer screws - anchors. After that, the anchors are screwed in. It is checked again for distortions. In many cases, when installing a door, a different gap is formed between the door trims and the wall. In this case, the door is installed in a level and does not have distortions. This indicates the unevenness of the wall of the room.
Many not sufficiently experienced builders do not take this moment into account and install the door close to the wall, as a result of which it may not close from the skew caused by the unevenness of the wall. Next, a lock is installed, and the door is again checked for distortions. Lock actuation is tried.
After fixing with anchors and checking the correctness of installation and the absence of distortions, ease of closing - opening, we begin filling the cavity between the box and the wall with polyurethane foam, given that after hardening, the volume of foam increases by three times. After 3 - 4 hours, the excess foam is cut off. All is ready!
