What is aluminum alloy doors and windows, I am afraid that someone may not understand. Aluminum alloy is a new type of material with light weight, high strength, good electrical and thermal conductivity, beautiful appearance, and environmental protection. It has excellent mechanical properties and processing performance.

Learned from the Guangdong Provincial Bureau of Quality and Technical Supervision official website, recently, the national standard "aluminum alloy bridge structure extruded aluminum profile" was officially released by the Guangdong Yongli Aluminum Industry Co., Ltd. and other 15 enterprises and institutions.
