Function1. Material structure: High strength aluminum alloy profile (6063-T5);Modular assembly process, no welding points, beautiful appearance of the door structure, compact structure, surface treatment by spraying,The product chooses Dutch Aknobel electrostatic powder, good weather resistance.The mechanical properties and chemical composition of materials conform to the current national standards;2. The door body can be stacked for multiple pieces to solve the problem of shrinkage after the door is in place. The number of laminated pieces can be 2-5 pieces (according to the length of the user);3. The motor is equipped with overheat and overload protection device. When the motor temperature exceeds 120℃, the motor will automatically stop running to protect its service life;4, the upper and lower frames of the door can be selected to prevent rain, snow, sand and dust into the structure, to ensure that the adverse environmental conditions will not affect the normal use of the door;5, emergency stop function: when the door body is in the running state, in case of emergency, you can quickly cut off the main control box power through the emergency stop switch;
