Material: The main use of high-strength aluminum alloy, the main material thickness 1.2mm-2.5mm, DPM thickness 1.0mm, Size: through oxidation, to ensure that 20 years without fading. 
 Motor: the turbo motor, retractable door system designed with power 220V, Power 300W, frequently used in both positive and negative start and so on, increase the torque output. 
 Features: 
 1, the cross bar on a breakthrough in the five-hole one punch forming technology, compared with the normal drilling can extend the service life of more than 5 times, each hole is equipped with wear-resistant nylon cover, the service life of up to 10 years; nose Magnetic limit switch limit is adopted, no contact, to limit position automatically stop running. 
 2, the buffer device that can withstand the strong momentum when the motor starts, to keep the door open row of smooth, protect and extend the retractable door mechanical life; 
 3, PA high strength wear-resistant plastic instead of metal guide slot guide slot, thus reducing the movement of the sliding noise ' 
 4, the inclined tube holder connected with wear-resistant composite plastic PA to make running more lightweight and flexible; 
 5, cross-tube chassis with two cross pipes to replace the bottom three, so that gravity chassis suffer reduced life expectancy; 
 6, with plastic stand to replace the original aluminum tripod, and tripod to make a more beautiful one go; 
 7, infrared automatic setback feature anti-collision, encounter obstacles 30 --- 60 cm can automatically back to reduce damage to vehicles and pedestrians; reduce accidents; 
 8, the motor is equipped with heat-sensitive devices and time protection, extends motor life; 
 9, digital remote control system, 100 meters from start easily; 
 10, take the wheel with wear-resistant rubber material, equipped with needle bearings, wear, noise, and dust cover with water; 
 11, the door body and head with soft connection, ensure door and head start in frequent loose under the no. Insulated wire door E-class, anti-aging, minus 30-50 degrees in normal use; sophisticated clutch keys, listening to light when the power is 90 degrees rotation, transposition can be easily installed manually; 
 12, no belt drive to reduce the failure rate; IC circuit, electric shock-free control of the whole circuit, safe and reliable.
