Modular Steel Structures: An Efficient Solution for Green Buildings
Driven by the "dual carbon" goals, modular steel structures have emerged as a new trend in the green building sector due to their environmental and efficient characteristics. Compared to traditional concrete buildings, modular steel structures adopt a factory prefabrication and on-site assembly model, which can shorten the construction period by more than 30%, reduce on-site construction pollution and material waste, and are particularly suitable for time-constrained urban renewal and industrial park projects.
Its core advantage lies in "full-life-cycle recyclability" - the steel recovery rate exceeds 90%, much higher than that of concrete materials. Moreover, the prefabrication process can precisely control material consumption, avoiding material loss in on-site pouring. Meanwhile, the modular design offers high flexibility, allowing adjustment of unit sizes and functional combinations according to project needs, which can be applied to various scenarios such as commercial complexes, talent apartments, and industrial plants. For example, a standard factory building in a Yangtze River Delta industrial park using modular steel structures not only completed construction two months ahead of schedule but also reduced carbon emissions by 15% through steel recycling and energy-saving designs, thus being awarded as a local green building demonstration project.
In terms of performance, modular steel structures can achieve a seismic grade of over 8 degrees through optimized node connection technology. Meanwhile, equipped with sound insulation cotton and thermal insulation layers, they can meet the acoustic and thermal requirements of residential buildings. It is worth noting that the integration of BIM technology enables "digital construction" for modular steel structures, with full visualization from design modeling to construction simulation, effectively avoiding construction errors and reducing later operation and maintenance costs.
In the future, with the continuous advancement of prefabricated building policies, modular steel structures will further break through technical bottlenecks and make breakthroughs in the standardization of modular units and the research and development of intelligent assembly equipment, becoming a core force in promoting the low-carbon transformation of the construction industry.
