With the rapid progress of large-scale investment in construction  industrialization in China, aluminum alloy profiles have been widely used in fields such as construction, chemical industry, power, transportation, military industry, aerospace,  mechanical light industry manufacturing due to their excellent processing performance, light weight, multiple varieties,  complete specifications. Especially in China's transportation industry, the trend of lightweight will become more apparent. The implementation of lightweight  high-speed transportation tools  other aspects for the purpose of energy conservation  environmental protection, reducing environmental pollution,  increasing safety  comfort is the main feature of the current development of the aluminum profile industry. At present, the demand for energy-saving, environmentally friendly,  corrosion-resistant aluminum profiles in the market is increasing day by day,  there is a strong demand for high-end aluminum alloy profiles.
