Installation method of door hinges

1. Before installing the door hinges, it is necessary to check whether the door hinges match the door and window frames and sashes.
2. Check if the hinge slot matches the hinge height, width, and thickness.
3. During installation, it is necessary to check whether the hinge and the screws and fasteners connected to it are compatible.
4. The connection method of hinges should match the material of the frame and leaf. For example, the hinges used for steel frame wooden doors are welded to one side of the steel frame, while the wooden door leaf is fixed with wooden screws.
5. In the case of asymmetric hinge panels, it is necessary to distinguish which panel should be connected to the fan. The side connected to the third section of the shaft should be fixed to the frame, and the side connected to the two sections of the shaft should be fixed to the frame.
6. During installation, it should be ensured that the axis of the hinges on the same panel is on the same vertical line to prevent the door and window panels from warping.
