“As the construction industry is advancing toward green environmental protection, providing mold-frame products with low emission, low loss, automation and light weight for green construction will be the development trend of China’s formwork industry. For example, plastic formwork, aluminum alloy formwork, etc. Its advantages of lightness, durability, environmental protection and high efficiency have won recognition and high praise from the market.” At the 2018 High-Level Forum on Expanding Aluminum Applications held recently, Gao Feng, Secretary General of the China Formwork Scaffolding Association said.

It is understood that in modern civil engineering construction, concrete structures occupy a dominant position. Concrete structures in developed countries such as the United States account for more than 50% of all projects, while in developing countries such as China, this proportion can reach more than 80%. In Japan, the cost of formwork works accounts for 40% to 45% of the cost of concrete structures. In the United States, the cost of formwork projects accounts for about 35% to 60% of the cost of concrete structures, accounting for about 10% of the total project cost.

“In China, the cost of formwork projects accounts for about 25% to 35% of the total cost of cast-in-place concrete structures, accounting for 50% to 60% of the total construction period. Expenses account for about 5% of the total project cost.” Gao Feng said, “ In the future, the total output value of the mold-related industries is expected to reach 1 trillion yuan.”

It can be seen that the proportion of the production of the formwork-related industries in both developed countries and in the construction sector in China is quite large. Since the beginning of the new century, with the upgrading of new construction technology, high efficiency and high quality requirements in the construction industry, coupled with the country’s environmental protection requirements and the increasing labor costs, the development and application of new building templates has become a catalyst for technological innovation. Reduce the cost of construction and help the construction industry to modernize.

Gao Feng said: “Aluminum template will have great potential for development in the next few decades.” He pointed out that aluminum template technology has been more than 50 years old, and has been in Europe, North America, Japan, South Korea and other countries. Get a wide range of applications. In recent years, due to its series of excellent characteristics, it is also increasingly favored by domestic construction companies.

According to statistics, in 2017, the application of aluminum template products has involved more than 30 provinces and cities nationwide. There are more than 500 aluminum template manufacturers in the country, and in the past three years, the annual growth rate has reached about 18%. The current market share is about 18%. The output in 2017 is estimated to be around 25 million m2. In 2018, the new production is expected to reach 40 million to 50 million m2, and the total amount will reach 120 million m2.

For the aluminum formwork industry, why can such a high-speed development, the peak believes that, first, the performance advantages of aluminum formwork products, aluminum formwork has light weight, high precision, clear water concrete effect, turnover times, convenient construction, good corrosion resistance, waterproof A number of distinctive advantages such as good sex, strong fire resistance and high recycling value. Second, in the past 40 years, the practical experience of China’s formwork industry and the rich accumulation of basic research, the Chinese formwork industry has actually formed a relatively complete industrial system of scientific research, manufacturing, standards, construction, innovation and application. The third is the quality upgrade promoted by the supply-side structural reform, and the template industry has been upgraded from the traditional low-end price market to the demand of the mid-to-high-end market.
At the same time, the peak also pointed out that aluminum alloy formwork also has some shortcomings in the engineering application process. For example, when the aluminum alloy formwork is used after repair, the ash at the concave corner is heavy, the cleaning is difficult, and the efficiency is low; the surface of the aluminum alloy template is easy to Concrete reaction, affecting the quality of the forming surface, requires high quality mold-keeping agent and mold release agent to meet the demand; too many specifications and varieties, low non-standard template usage rate, affecting the turnover rate.

“Accelerating the development of new formwork technology, strengthening the upstream and downstream interactive communication in the industry, and vigorously promoting the professionalization of formwork construction” are three suggestions put forward by the peak for the development of the formwork industry, and also apply to the aluminum alloy formwork industry.

All in all, with the promotion of aluminum alloy formwork by a number of real estate developers such as Vanke and Country Garden, the aluminum alloy formwork industry has formed a relatively complete construction system. “The future aluminum alloy formwork market will gradually enlarge and usher in a spurt of growth.” Gao said.
