The installation of the entrance door is fixed by the expansion bolts in the screw holes of the surrounding door frames. If you want to adjust the angle, you can loosen the expanding tube and adjust it slightly. Generally, there will be no major changes. If the gap is too large, it is necessary to remove the expansion bolt, re-drill the hole and install it.

The main entrance doors are pure steel entrance doors, stainless steel doors and armored door. Among them, armored door is a high-grade entrance. Its main feature is that a layer of wood skin is added to the surface of the steel entrance door to replace the traditional surface treatment method, which not only ensures the safety factor of the entrance door, but also greatly improves the grade of the door. At the same time, it can be better coordinated with interior decoration.
