Sectional Door

For sectional door, the door plate adopts a double-layer sandwich hot dip galvanized steel plate with polyester surface treatment; the core material is a polyurethane insulation layer, and the thickness of the door plate is 40mm-50mm, strong, heat insulation, heat preservation, dustproof, wind pressure resistance. The track is made of hot-dip galvanized steel plate, which is solid and durable, and the external torsion spring balancing system has a life of more than 50,000 times. There are two kinds of sealing strips inside and outside: frost-proof, dustproof, and heat-insulating.
