Security door type
- Aug 20, 2018 -

The fence type anti-theft door is a common anti-theft door welded by steel pipes. Its biggest advantage is ventilation, light weight, beautiful appearance and relatively low price. The upper part of the security door is a fence type steel pipe or steel plate, and the lower part is a cold-rolled steel plate, which is locked by multiple lock points to ensure the anti-smashing ability of the security door. However, it is not as good as the closed security door in the anti-theft effect.


The solid door is extruded from cold-rolled steel plate, and the door panels are all steel plates. The thickness of the steel plate is 1.2 mm and 1.5 mm, and the impact resistance is strong. The door double-layer steel plate is filled with rock wool insulation fireproof material, which has the functions of anti-theft, fire prevention, heat insulation and sound insulation. General physical security doors are equipped with cat eyes, doorbells and other facilities.


The composite anti-theft door is composed of a solid door and a fence-type anti-theft door. It has the characteristics of anti-theft and summer fly-proof mosquitoes, ventilation and cooling, and warm insulation in winter.
