Aluminum Alloy Formwork

Visits : Release time :2017-12-29

With the characteristics of high precision and large rigidity, the aluminum alloy formwork can optimize the secondary structures such as lower hanging beam and structural column to make it casted at a time, and can be used to make the shear wall free from plastering, thus reducing the construction cost and construction difficulty. As of December 2017, the aluminum alloy formwork has been applied in 50 individual works of 18 projects, with a cumulative site area of 121,000 square meters and a construction area of 1,384,000 square meters.
