Problems solved by technology

For many years, in the curtain wall market of the construction industry, the profiles used for glass curtain walls are made of aluminum alloy at one time. With the continuous development of urban construction, people have more and more requirements for the grade of curtain walls made of glass or other materials and the profiles used. The higher the height, especially the high-rise or ultra-high-rise buildings, the traditional use of aluminum alloy as curtain wall profiles can no longer meet the requirements of anti-corrosion ability, strength and load capacity required by the building.
