Do you know how to buy fast door?

Generally fast gate, is a more flexible door. It is mainly used in various types of large warehouse and factory floor, of course, is to prevent theft, safe to use.


First, I want to see whether the door is made of aluminum alloy rapid material because aluminum material has not so easy to rust, especially corrosion resistance, of course, it is also a great strength, but toughness is also large, the most important is the life of an aluminum alloy long, you can save a lot of money for our pockets.


Next is the shutter curtain sheet, must be well attached to the aluminum powder, so easy to produce scratches and more beautiful, resistant to general corrosion of acid rain, as well as to minimize friction dust blow, this way is very durable up.


Then we would look at the secondary security protection, cover semi-automatic lock structure its shutter shaft, as well as whether it can effectively reduce the wear, noise and so on.


Finally automatic balance and control structure, at least be able to effectively protect the normal operation of the motor to reduce losses caused by the work, while launching Accessible easily control it at 20 meters wireless.
