1. The door panel industry sliding door
The total thickness of the door panel is 40mm ± 1mm, and the double -sided 0.5mm thick and steel steel color coating plate. Pressure reinforcement reinforcement door panel strength. The two -layer steel plate is filled with hard polyurethane foam, with a density of about 40kg/cubic meter, and the thermal conductivity is less than 0.033W/m.k. There is a continuous steel belt at the installation hinge position to ensure firmly installation of the hinge. At the door panel above 5m, a height 80mm enhanced reinforcement is set on the inside of each door to ensure that the door panel has a wind resistance of more than 12 or more. There is a Sanyuan E -Curetic sealing strip at the bottom of the sub -door panel, which is equipped with airbags in the sealing strip. The seal heads on the second side of the door panel are Δ = 1.0mm galvanized steel plate sealing tablets.
2. Hardware accessories:
The door panel connection hinge is made of hot -dip galvanized cold -rolled steel plate. The thickness of the material is Δ = 2.0mm, and the thickness of the galvanized zinc is greater than 28µm. The 3 -inch
industrial door of the conductor of the guide rail is Δ = 2m -hot -dip galvanized steel roller, Zhuan use the guide rail; the shape of the guide rail section has anti -decoupling to ensure that the guide wheel runs smoothly in the guide rail; Made of roller pressure, the sheet is equipped with a slot on the door seal rubber and the installation holes connected to the guide rail; the guide wheels φ72mm
industrial door zhuan uses a guide wheel. No noise. The remaining hardware accessories are made of hot -dip galvanized steel plates, which are accurate size and good interchangeability.
3. Balance system: The sliding door uses twist spring balance, and the balancing twist spring is designed and produced by the door weight load software to make the balance reach the best state. Select 60si2mn imported spring steel for twist spring materials to ensure that the service life exceeds 80,000 cycle cycles. The balancing shaft of the sliding door is 525.4 solid round steel. It is equipped with a twist spring fracture protection device on the balance shaft. This device can prevent the door panel from falling when the balancing twist springs break;
The safety factor of the steel wire rope is more than 5 times the weight of the door, and the anti -steel wire rope is broken on the door panel to ensure the safe operation of the door panel.
