Class c has high anti-theft performance, followed by class b and class a. Most markets are Class A, which is generally suitable for ordinary families. Class A requires all steel, flat and fully enclosed: mainly the interaction between ordinary manipulator tools and portable electric tools. Weak connection can resist abnormal opening time ≥ 15, otherwise it should not be cut off. A hole of 6 15 cm 2 passes through the door.
2. When buying a rolling door, look at the numbers. Generally, the size of qualified fire doors is smaller than the sample size. The thickness of the door leaf is greater than or equal to that of the sample, and the width of the side wall of the door frame is greater than or equal to that of the sample.
3. When purchasing a rolling shutter door, whether the electric rolling shutter door supports the manual function is convenient. When the power is cut off, the clutch twists 90 degrees to push the hand. The electric shutter door will not slide and has the function of double-sided automatic locking. In order to improve the running stability of electric shutter doors, it is necessary to increase the tension. Therefore, the factory adopts the production and installation technology of 8-wheel front-rear drive and continuous rotation of gears.

Many electric garage doors in China don't have this function, and they can usually be opened during power failure, but there is no way to lock them, which has caused a lot of unnecessary trouble. Many existing garage doors have patented double lock mechanisms. When the power is off, you can manually open or lock the door with the key.
