Green and Efficient: Steel Structures Conform to the New Trend of Sustainable Development
2025-09-23
As the "dual carbon" goals are advanced in depth, green and environmental protection have become the core direction for the development of the construction industry, and steel structures are a paradigmatic practice of this concept. From the perspective of raw materials, steel can achieve 100% recycling — whether it is steel from demolished buildings or leftover materials generated during the production process, all can be reprocessed and put back into use. This significantly reduces the generation of construction waste, lowers the consumption of natural resources, and truly realizes "low-carbon environmental protection throughout the entire life cycle of buildings". In terms of construction efficiency, steel structures further demonstrate the advantage of "fast pace". Components of steel structures are mainly produced through standardized prefabrication in factories, with precision reaching the millimeter level, and then transported to the construction site for assembly and welding. This "factory prefabrication + on-site assembly" model not only reduces dust and noise pollution from on-site operations but also shortens the construction period by 30%-50%. Taking a 10-story steel-structured office building as an example, it only takes 3-4 months from component production to the capping of the main structure. Compared with the 6-8 months required for traditional concrete structures, this greatly accelerates the project delivery speed and helps customers achieve investment returns in advance. With excellent performance and flexible design, the application scenarios of steel structures have covered various fields in the construction industry, providing customized solutions for customers in different sectors. In the field of industrial construction, steel-structured workshops can meet the production needs of large spaces and high clear heights. They allow flexible arrangement of production lines and hoisting equipment, and possess good durability to resist issues such as corrosion and vibration in industrial production, thus being widely used in industries like machinery manufacturing, automobile production, and warehousing and logistics. In the field of public construction, steel structures have become the core choice for building urban landmarks. From the "steel phoenix" roof of Beijing Daxing International Airport to the "four-leaf clover" shape of the National Exhibition and Convention Center (Shanghai), steel structures, with their strong shape plasticity, turn designers' ideas into reality. They not only showcase the artistic beauty of architecture but also ensure the safety and comfort of public spaces. In the field of residential construction, steel-structured residential buildings are gradually becoming a new trend. Their indoor space layout is flexible and can be divided freely according to residents' needs. Moreover, they have good sound insulation and heat insulation performance — with the addition of thermal insulation layers and sound insulation materials, their living experience is comparable to that of traditional residential buildings. At the same time, steel-structured residential buildings have excellent seismic performance, providing residents with a safer living environment.
