In China, aluminum alloy has been applied in industrial and civil buildings to make roofing, walls, doors and Windows, and has gradually expanded to interior and exterior decoration, construction formwork, etc., and has achieved good results.

Characteristics and uses Aluminum and aluminum alloys are the biggest characteristics, first of all, the bulk density of about one-third of steel, and specific strength (strength limit to specific gravity ratio) can meet or exceed structural steel. Secondly, aluminum and aluminum alloy are easy to process into a variety of shapes, can adapt to a variety of connection technology, so as to provide favorable conditions for the construction of the most economical and reasonable section form. Therefore, the use of aluminum alloy can not only greatly reduce the weight of the building, save materials, but also reduce the transportation of components, installation workload, speed up the construction progress. This for the earthquake area and transportation inconvenient mountainous and remote areas, its economic effect is more significant. Aluminum and aluminum alloy color beautiful, good corrosion resistance, high reflectance to light and heat, good sound absorption performance, through chemical and electrochemical methods can obtain a variety of different colors. Therefore, aluminum is widely used in roofing, walls, doors and Windows, skeletons, interior and exterior decorative panels, ceilings, suspended ceilings, railings, interior furniture, store containers and construction templates, etc.

The construction industry is one of the three major markets for aluminum. About 20% of the world's total aluminum production is used in the construction industry. The construction industry in some industrially developed countries already uses more than 30% of its total aluminum production. The products of building aluminum are constantly updated, and the application of novel building products such as color aluminum plate, composite aluminum plate, composite door and window frame, aluminum alloy template is also increasing year by year. In China, aluminum alloy has been applied in industrial and civil buildings to make roofing, walls, doors and Windows, and has gradually expanded to interior and exterior decoration, construction formwork, etc., and has achieved good results.
