The selections of high quality fast rolling shutter door

1. Motor. Now the market competition is very fierce, some fast door manufacturers in order to ensure profits, they buy some jerry-built motor, which leads to the use of fast door, the brake rectifier block in the motor problems, serious even motor burned. So we should look at the quality of the motor and what brand it is when we buy the fast rolling shutter door.

2, Limit. limit is to ensure that the fast door stops at the specified position, to avoid the door opening scale is too large. If the fast rolling shutter door manufacturer uses mechanical limit, there is no problem. However, if the electronic limit is used, it will affect the work of the brake if it is disturbed in the process of use. After a long time of accumulation, the distance of the limit will be more and more large, which will seriously lead to serious wear of the brake pads. So when we buy fast rolling shutter doors, we try to choose high precision mechanical limit, or products with strict requirements on limit.

3. Door curtain. We can discover some door shade to look dirty in the life, such, basically be because door shade has self-clean function only one side, do not have another side, the cost that does so is lower. So when we buy fast doors, we choose the curtain with double-sided self-cleaning function.
