There are many choices of industrial and commercial door types to choose from, and the various options can be a little over whelming at first.
Kwang Doors supply a very wide range of roller shutter doors for the industrial sector where the environment is often harsh with high use requirements and sometimes very large sizes.
Industrial warehouses and factories can often also be exposed so the wind becomes a key factor in the specification for the roller doors used.
Industrial Roller doors can be separated into multiple categories depending on different uses and requirements. High usage and Low usage, and this defines the need for either a single or three phase electric motor drive system. A single phase motor is not to be used if the door is to open and close many times every day, especially if the door is very high, as this means the motor is operating for longer periods during opening and closing.
