Product characteristics:
The industrial sectional door is applied to the outdoor passage, logistics center and external door of factory, the door lanel is made of double-layer hot-dip galvanized embossed steel plate, and the enven columnar stripe is pressed on the surface. The core materials are polyurethane, the heat resisting coefficient is R-14.96, 18.25 and the flame-retardant test reaches A level; The back plate of door panelis equipped with the steel reinforcing band, which can resist the attack of strong wind that is more than 120km/h. The bottom U-shaped ethylene resin, aluminum alloy baffle plate of ddor hemline, and between rail and wall in the door opening range and door top, which all have sealing strips, the side and top are sealed by sealing strip with slot, and the connection point between door panels is sealed by concave&convex slot and heat insulation pipe, all-round full sealing forms the perfect closed environment, which is anti-freeze, dampproof, waterproof and prevents energy sources from losing. (safety)balance system uses the built-out torsional spring balance, the service life of which reaches up to 50000-100000times of working cycles. According to the demand various specifications of small doors of passage and small observed windows can be selected when the width of door body is less than 5500mm, the individual desigh can be implemented according to your requirements, and MEIMAN can always provide you the best scheme.
