1 First of all, look at the material selection of aluminum alloy rolling shutter doors. Generally, the aluminum profiles used in high-quality rolling shutter doors must meet the national standards for thickness, hardness, and oxide film. If they fail to meet the standards, they will be inferior aluminum alloy shutter doors.
2Then we must look at the processing of aluminum alloy rolling shutters. The high-quality roller shutter doors have finer processing and better sealing. They are very elegant when installed, and their switches are also comfortable. The inferior aluminum alloy shutter doors do not meet the requirements when selecting aluminum profiles. Standards, coupled with the rough production process, led to its first sealing performance, the switch can not be freely, if bad, there will be a phenomenon of air leakage or even explosion, it is easy to cause personnel injuries.
3 Finally, look at the price. Under normal circumstances, the cost of high-quality aluminum alloy rolling shutters is very high, and the poor quality is about 30 percent higher.
