Aluminium formwork holds great promise in the field of construction

On November 27th, “Extending Aluminum in the Construction Industry Application Forum”, Luo Tiejun, Deputy Director of the Department of Raw Materials of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology will encourage the expansion of buildings in the “13th Five-Year Plan” development plan for the non-ferrous metals industry. Application of aluminum formwork, foam aluminum seismic housing and aluminum structure movable board house in the construction field. Aluminum template enterprises are encouraged to gradually shift from the eastern coast to the western region, reduce production costs and expand the western market.

"Expanding the use of aluminum is the key to effectively resolving excess capacity," Luo Tiejun said in an exclusive interview. According to statistics, since 2013, the country has shut down 3.38 million tons of electrolytic aluminum production capacity. In 2013, the investment in fixed assets of the aluminum smelting industry fell by 12% year-on-year; from January to September this year, it decreased by 31% year-on-year, and the overheating of investment in electrolytic aluminum projects was significantly curbed. At the same time, investment in the aluminum rolling processing industry has grown significantly, from January to September this year, a year-on-year increase of 26.5%. This "a drop of one liter" indicates that the investment structure of the aluminum industry is being extended to the downstream and the structure has been continuously optimized, but the pressure to resolve production capacity is still very high.

"Aluminum formwork industry has significant energy-saving and emission-reduction effects." Chen Quanmian, president of the China Nonferrous Metals Industry Association, has calculated an account. Aluminum is a renewable material. The domestic aluminum formwork can be turned 200 to 300 times, while the wood formwork is only 3 to 5 times. . Aluminum template with 25 to 30 kg of aluminum per square meter, the recovery value of about 400 yuan. Substitution of the aluminum formwork for the wooden formwork significantly reduces the use of wood. Last year, the amount of building templates used in China exceeded 800 million square meters. If 20% of them were replaced with aluminum templates, 160 million square meters of timber templates could be saved, equivalent to saving 400,000 tons of standard coal and reducing 1 million tons of carbon dioxide. In addition, the aluminum template installation is 3 to 5 days less than wood or steel molds. The construction speed is fast, and the stability is good, the bearing capacity is strong, the surface quality of the concrete is smooth, the plastering process can be reduced, and the wall surface quality is good.

According to statistics, at present, only 60 to 80 companies are registered in the production of aluminum formwork in China. In 2013, the output of aluminum formwork was only 500,000 square meters, which was less than 1% of the total amount of formwork. Chen Quanxun believes that according to the current development trend, the market share of aluminum formwork will greatly increase. If the aluminum formwork market share reaches 10%, the amount of aluminum used will reach 2 million tons.

"China has not yet established a unified aluminum formwork product standard, which is not conducive to standardization of production, affecting product quality and versatility, reducing the number of turnover, thereby reducing the overall benefits of aluminum templates." Chen Quanxun said.

In this regard, Luo Tiejun revealed that the Ministry of Industry and Information Technology is working out related standards and norms, so as to promote the application of aluminum in the construction field. Luo Tiejun also stated that the cost of aluminum alloy formwork is higher than that of wood formwork and steel formwork, and there are a large number of non-standard items, which results in higher initial costs of sales and use of the enterprise. To encourage the full development of domestic leasing operations, thereby accelerating product promotion and application.
