Anti rolling shutter doors are particularly strong in wind pressure, high strength, good rigidity, strong structure, wind resistant hook in the guide rail, ensure that the curtain plate does not escape from the guide rail in the strong wind, and is suitable for the places where the wind resistance is required. Double layer stainless steel or aluminum alloy and stainless steel plate.
The composite curtain can be filled with fireproof cotton and thermal insulation materials, and has the functions of fire prevention, heat insulation and heat preservation. The material of the bottom beam is made of galvanized steel plate and stainless steel plate. The bottom beam with special profile machining, and stainless steel wire is connected with the cap curtain; sealing strip is arranged at the bottom of a special design, so that when the door is closed and the ground is completely sealed to prevent dust, rain intrusion, even if the ground roughness can also play a sealing effect.
Roller shutter is composed of wear-resistant rubber components, through the special process to install the door on the auxiliary shaft, to avoid the friction between the door and the auxiliary shaft, so as to play a role in the protection of the door coating. In the running process, the rolling door is always moved at the central position of the guide rail notch, so as to avoid the abrasion between the door curtain and the guide rail.
Roller breaking device greatly improves the safety performance of roll gate using additional components, is driven by the motor when the motor gear chain rupture, fracture, motor brake failure and other dangerous situations, this device can check the scroll, stop the curtain suddenly slipped, protect life and property safety of the user, when the rolling door is abnormal the situation, to accelerate the decline in the door body, the device can automatically cut off the power supply of the motor through the limit switch, at the same time to reel, so that the door body cannot fall.
The above is a small series for you to explain the knowledge, we have a strict working attitude, skilled work skills, will ensure that the task is accurate and efficient completion.
