At present, most of the aluminum curtain walls used in China are composite aluminum plates and aluminum alloy veneers. The advantages of composite aluminum sheet are light weight, smooth surface, good smoothness, no color difference in the same direction, and excellent on-site workability. It provides conditions for dealing with the variation of exterior wall size caused by on-site building errors, reducing workshop processing period and shortening installation period.

The composite aluminum sheet plate should be processed into wallboard when it is installed. Firstly, it should be cut according to the size of the second design. When cutting the board, the size of folding should be considered. Generally, each side should be placed about 30mm.

Galvanized strips are long, narrow strips of cold-rolled or hot-rolled steel with varying degrees of coating called zinc.

Aluminium sheet for curtain wall has a unique texture, rich color and lasting, and the appearance can be diversified, and can be perfectly combined with glass curtain wall materials, stone curtain wall materials. Its perfect appearance, excellent quality, light weight, only one fifth of marble, is one third of the glass curtain wall, greatly reducing the load on the building structure and foundation, and low maintenance costs, high performance price ratio. And aluminum curtain wall is not easy to stain, easy to clean and maintain. The non adhesion of fluorocarbon coatings makes it difficult to attach contaminants to the surface and has better cleanliness.
