　　The door panel connecting hinge is made of hot-dip galvanized cold-rolled steel plate stamping. The material thickness is δ=2.0mm, and the galvanized thickness is greater than 28 μ m. The guide rail is a 3-inch industrial door specific guide rail made of hot-dip galvanized steel sheet rolled with a thickness of δ=2mm; The cross-sectional shape of the guide rail is equipped with anti decoupling to ensure smooth operation of the guide wheel inside the guide rail; The guide rail guard plate is made of hot-dip galvanized steel plate with a thickness of δ=2mm and rolled. The guard plate is equipped with a slot for door side sealing rubber and installation holes connected to the guide rail; The guide wheel is a special guide wheel for industrial doors with a diameter of 72mm. The guide wheel material is wear-resistant nylon, which contains roller bearings and runs smoothly without noise. The remaining hardware accessories are made of hot-dip galvanized steel sheet stamping, with accurate dimensions and good interchangeability.

　　2. The door panel of Hongfa Industrial sliding door

　　The total thickness of the sliding door panel is 40mm ± 1mm, with double-sided 0.5mm thick Baosteel color coated steel plate. The coating treatment from top to bottom includes polyester coating, primer, passivation layer, galvanized layer, orange embossed pattern, and positive and negative noodle shaped ribs to strengthen the strength of the door panel. A hard polyurethane foam material with a density of about 40kg/cubic meter and a thermal conductivity of less than 0.033W is filled between the two layers of steel plates. A continuous steel strip is installed at the hinge installation position to ensure a secure installation of the hinge. A 80mm high reinforcing rib is installed on the inner side of each door panel above 5m to ensure that the door panel has a wind resistance strength of at least level 12. There is a EPDM rubber sealing strip at the bottom of the segmented door panel, which contains an airbag. The heads on both sides of the door panel are made of δ=1.0mm galvanized steel sheet heads.

　　3. The safety protection device of Hongfa Industrial sliding door:

　　① A safety airbag is installed at the bottom of the door, which can automatically reverse to the fully open state when encountering obstacles during the closing process of the door;

　　② At the bottom two ends of the door, there are blade type wire rope breakage protectors. When the lifting wire rope breaks and the door body moves faster, the device can cut into the guide rail to prevent the door body from falling;

　　③ When the motor is equipped with a disengagement clutch device and switched to manual mode, the door can be manually operated to move.

　　4. The balance system of Hongfa Industrial Sliding Gate:

　　The sliding door adopts torsion spring balance, and the balance torsion spring is designed and manufactured based on the door load software calculation to achieve balance. The torsion spring material is made of 60si2Mn imported spring steel, ensuring a service life of over 80000 cycles. The balance shaft of the sliding door is made of solid round steel with a diameter of 25.4. A torsion spring breakage protection device is installed on the balance shaft, which can prevent the door panel from falling when the balance torsion spring breaks; The lifting pulley is an aluminum cylindrical pulley.

　　Enhance the safety factor of the steel wire rope by more than 5 times the weight of the door, and install anti wire rope breakage measures on the door panel to ensure its safe operation.

　　5. Operation of industrial sliding door:

　　Lift the door operation manual control mode and electric control mode:

　　1) Manual control mode: The door can be manually raised and lowered in one go, and in the event of a power outage, the door can be manually opened.
