Industrial door plate adopts double-layer sandwich hot-dipped galvanised steel plate with polyester surface treatment, the core material is polyurethane insulation and heat preservation layer, the thickness of the door plate is 40mm automatic line anti-clamping door plate, which is sturdy, heat-insulating, heat preservation, dust-proof, and wind-pressure-resistant.

The track is made of 2.0mm hot-dip galvanised steel plate, which is strong and durable. The external torsion spring balance system has a service life of more than 100,000 times, and there are two kinds of sealing strips inside and outside, which are frost-proof, dust-proof and heat-insulating. The end face of the door body is equipped with a box-shaped sealing edge, and the coupling hinge is mounted on the sealing edge, so that the door body is embedded in the track. Bottom and top seals made of spherical vinyl are fixed along the width and height of the door to prevent wind, rain and infiltration. The door body balance system is driven by torsion springs and chains on both sides, which are connected to the bottom of the door body with an anti-breakage device of steel cables, which is superior to the ordinary wire rope sliding door and has a low failure rate.

When closing the door, there is a door body anti-jam air-sensitive safety bag rebound function, when encountering resistance or obstacles, the door control system device will make the door body automatically rebound, to avoid causing injury to vehicles or pedestrians.
