Aluminum alloy formwork technology already has a history of more than 50 years in foreign countries. Since its appearance in 1962 in the United States, it has been used in developed countries, such as the United States, Canada and European countries, as well as Mexico, Brazil, Malaysia, South Korea, India, Hong Kong and Macao of China for more than a decade.
At present, China has accelerated the process of urban development. In order to provide capacity, both high-rise and super high-rise adopt reinforced concrete as main body, which provides conditions for building industrialization, standardization and mechanization.
The aluminum alloy formwork have many advantages, including light, easy disassembly and assembly, high rigidity, good stability, high precision, smooth surface of pouring concrete, long service life, large number of turnovers, good economical efficiency, high residual value, fast construction progress, high construction efficiency, construction safety, clean, low dependence on machinery, wide range of application and so on. It is now mainly used in Pearl River Delta area, Yangtze River Delta area, Hunan Province, Hubei Province, Yunnan Province, Guangxi Province, Fujian Province and southwest regions.
