Metal doors, most often, come to the installation already assembled: the door leaf is fitted in a door frame and hung on hinges. All the locking hardware is cut, so installing the door will not be very difficult.
To insert a metal door you will need:
- tape measure;
- level;
- hammer;
- drill-perforator;
- socket wrench number 17;
- screwdrivers;
- grinding machine;
- metal door with a box.
1. Before installing the door, check its quality: the door leaf must not touch the frame when it is opened.
2. Check and prepare the doorway( its size should be 2 cm more than the size of the door frame).The inside of the opening must be checked for verticality. Quite often, when measuring between vertical lines, there is a need to expand the opening.
3. Start the installation of the door frame without the door leaf from the outside of the opening. If the frame is not too rigid, then the door frame can be assembled with the door itself. However, the whole door is quite heavy and causes inconvenience in the installation.
4. Fix the frame or the entire door assembly in the opening with the help of wooden wedges. Install the wedges between the end of the opening and the frame on the inside of the door.
5. Now carefully hang the door leaf, if necessary. Be sure to lubricate the hinges, otherwise there may be an error in the future due to friction in the hinges. If the frame is installed correctly, the door leaf will remain stationary when it is open in any position.
6. Depending on the type of fasteners, drill holes in the wall of the required diameter for the bolts and fittings. There are three types of fastening of metal doors: fastening with anchor bolts or punching fittings with further welding, fastening with anchor bolts through frames, fastening with drive armature with further welding to the frame. Currently, the plywood mount is very popular due to the zero probability of loosening the fasteners during operation. In order to increase the strength of the doorways, they are framed in a framework of metal corners and plates.
7. Insert all anchor bolts into the holes and hammer the pieces of the reinforcement. Tighten the nuts and weld the reinforcement only in the vertical frame posts at the middle level.
8. Hang the door leaf and check the inside tightness of the cloth to the frame. If necessary, adjust the tightness by moving the door frame.
9. After adjusting the position of the metal door, secure it around the perimeter.
10. The final stage of installing the metal door is to fill the space between the wall and the door with mounting foam. Do not forget to remove all the wooden wedges beforehand. That's all.
