Member Jia Zhenglan stated that building formwork, as an important material for construction projects, must follow the path of green, low-carbon, and sustainable development. Magnesium alloy building templates, as an emerging green building material, play an important role in conserving forest resources, protecting the ecological environment, and supporting the “dual carbon” strategy..
China already has the advantages and industrial foundation to develop magnesium alloy building templates:.
1. The abundant magnesium resources provide a solid raw material guarantee for downstream applications of magnesium. Magnesium has absolute resource advantages in China and is the only commonly used metal material that is 100% self-sufficient and has strong international competitiveness. Magnesium alloy is a key green new material encouraged by the country. The Classification of Strategic Emerging Industries includes magnesium alloys as a strategic emerging industry. The Guiding Catalogue for Industrial Structure Adjustment lists high-performance magnesium alloys and their products as encouraged projects, encourages the development of diversified magnesium alloy materials and their processing and manufacturing such as casting, extrusion, rolling, forging, etc., and cultivates a new material industry chain. The Catalogue for the Demonstration of the First Batch Application of Key New Materials lists high-performance magnesium alloy extruded materials as advanced basic materials..
2. Magnesium alloy building formwork has many advantages. The mechanical properties of magnesium alloy building templates processed by extrusion deformation are similar to those of aluminum alloy, and the advantages are more obvious. One is high turnover, less construction waste, and occupies less space; Secondly, the construction quality is excellent, and the board surface is flat; Thirdly, the cost is lower, with the same weight of metal magnesium and metal aluminum, magnesium can produce 33% more building templates; Thirdly, the construction efficiency is higher, and the magnesium alloy formwork is lightweight, which improves the work efficiency of workers and machinery; The fourth is better heat dissipation, which meets the construction needs of offsetting the heat generated by water condensation during pouring and vibration; Fifth, it has lower safety risks, lighter weight, safer construction for workers, and lower incidence of occupational diseases, making it an ideal new type of green building material..
The market prospects for magnesium alloy building formwork are promising. The data for 2023 has not been released yet. Taking 2022 as an example, the construction industry in China has completed a housing completion area of 4.055 billion square meters. Based on an average of 20 floors, using wooden templates requires about 2.38 billion square meters of templates, consumes 49.16 million cubic meters of wood, and has a low reuse rate; Using alloy templates only requires approximately 640 million square meters of templates and can be reused..
4. Magnesium alloy building templates are currently in the initial stage of application and promotion, but the market has reached a general consensus on the prospects of magnesium alloy materials and magnesium template applications, and state-owned and private enterprises are gradually entering this field. Among them, Zhongtian Era Magnesium Industry has taken the lead in establishing the world’s first magnesium alloy building template research and development center and the first magnesium alloy building template pilot production line. It has completed research and development, testing, and multiple trials, and has the conditions for large-scale production and promotion of application..
During the research, Committee Member Jia Zhenglan found that there are still some difficulties and obstacles in the application and promotion of magnesium alloy templates. Due to the systematic design, standardized management, and safe use of magnesium alloy building templates being important factors restricting the entry of products into the construction industry, it is urgent to establish standards and carry out pilot applications..
To this end, Committee Member Jia Zhenglan proposed two specific suggestions: firstly, the Ministry of Housing and Urban Rural Development will take the lead in organizing industry associations and leading enterprises to formulate national standards for magnesium alloy building templates, and standardize and guide the entry of magnesium alloy building templates into the market..
