Problems solved by technology

However, there are three major problems in doors and windows using heat-insulating aluminum alloy profiles: one is that the cross-sectional area of ​​aluminum alloy doors and windows increases, which increases the consumption of aluminum alloys (the weight of aluminum alloys generally needs to be increased by more than 60%), and also increases the size of doors and windows. The second is the non-metallic materials used in the middle, most of which are plastics, which will age after a long time, affecting the strength and safety of doors and windows; the third is recycling for a long time, and plastics will produce secondary pollution
