- Product features
- Industrial sectional doors can provide a variety of lifting methods according to the actual civil structure on site: such as straight type, standard lifting type, high lintel lifting type, low lintel lifting type, etc, so that your building space can be customized.

- The door panel is made of sturdy material with double sided hot-dip galvanized steel, embossed on the surface and embossed stripe design, and the inner layer is a high-density polyurethane form insulation layer. The door panel has the function of preventing fingers from being pinched.
- The joints of the door panels are equipped with sealing rubber to ensure a good sealing effect. The front and back panels of the door panels are made of coated steel plates, which have high corrosion resistance and weather resistance.
- Panel: A. Two layer of 0.4mm powder coated galvanized steel plate, PU foaming density 48±2kg/m3;B. Surface printing layer: 30um; C. Total thickness: 40mm (standard) 50mm/75mm/100mm (optional)
- Safety device: 1. Spring brake device (anti-broken); 2. Service life: 100000 opening and closing; 3. Driving force: 140N;
- Accidient dropping safety device: Door bottom equips with the avoid dropping steel cord, to secure the accidient dropping within 50mm
- Guide rail: A. Special design three angle wheel brace secure smooth rolling of wheel; B. Mute nylon wheel, noise level: ≤60db
- Beam seals: Epdm sealing rubber is installed onto top, bottom and sides
- Buffer and hinges: 2.5mm steel plate
- Bottom wireless safety airbag: It makes the door doby lift back when touching somthing during closing and stops the movement during opening
- Lifting speed: 0.2m/s
- Door panel: Double layer hot-dip galvanized embossed anti-corrosive sprayed steel plate, door body polyurethane density is 48, door panel thickness is 40mm, door panel height is 510mm
- Track and hardware: Support the door body and guide the door boty to run, adopot high-quality anti-corrision metal guide rail, auxiliary rail and guide rail bracket, thickness 2mm.

- Wind resistance: ≥450N/m2
- Balance system: Use the power of the torsion spring to balance the weight of the door
- Torsion spring system: Including door shaft, torsion spring sleeve, torsion spring (lifespan is 50,000 times at least), sheave, coupling etc. The material is high quality torsion spring, with a lifespan of more than 30,000 times, and special processing technology
- Torsion spring anti-breaking system: After the door has been used for a certain number of years, the guide spring is easily broken when fatigued. The torsion spring anti-breaking system will lock the transmission shaft once the torsion spring breaks, thereby effectively avoiding greater safety accidents
- Wire rope anti-breaking device: The steel wire rope anti-falling device is installed at the bottom of the door panel, no matter when the door body moves up or down, the wire rope suddenly brakes, self-locking ensures that the door body will not suddenly slide down and prevent accidents
- Safety pressure switch: When the door body is pressed against an object during the descending process, the door body will instantly rebound and rise automatically
- Sealing: There is a sealing strip at the bottom, and the materail is made of EPDM material, which has the characteristics of anti-low temperature and anti-fracture, inliad installation, and good sealing effect, The surroundings are sealed to ensure the performance of rainproof, dust-proof, sound instaltion and heat insulation.
