Light-gauge steel structures are a natural green building material, as well as a natural industrialized construction choice. The development of such a structural system is highly in line with China's fast-paced urbanization and economic growth. Compared to traditional structures, light-gauge steel structures also offer numerous advantages.
The structure is lightweight, high-strength, has good seismic performance, and boasts favorable economic indicators.
The steel consumption for cold-formed steel building structures ranges from 20 to 35 kg/㎡, while traditional steel frame structures require about 50 kg/㎡. The reduced self-weight can effectively decrease the horizontal seismic effect on the structure, coupled with a reasonable structural design, resulting in good seismic performance. Additionally, the reduction in self-weight also lowers the requirements for foundation bearing capacity, potentially reducing the cost of the foundation.
2. Architectural design is aesthetically pleasing with high space utilization.
The wall panel structure features neatly arranged four walls, allowing for the design of buildings with vibrant colors, rich facades, and a modern vibe to meet customer needs. Pipes are concealed within the walls and floor structures, saving subcontractors time and costs, and making future repairs and maintenance simple. The wall thickness is reduced, increasing the utilization rate of the building by 5% to 7% compared to traditional structures.
High residential living comfort.
Cold-formed thin-walled steel residential structures utilize new building materials that are moisture, mold, and termite-resistant, non-combustible, ensuring a healthy living environment. They offer excellent heat and sound insulation, making them ideal living spaces.
4. Easy construction, eco-friendly, and short project cycle.
Construction on-site primarily focuses on the installation of components. For a typical three-story residential building, the entire process from design, production to completion of installation takes about a month.
5. Energy-saving, land-saving, and material-saving.
The primary structural materials used are cold-formed thin-walled steel, which requires less steel and is recyclable. All waste generated on-site is recyclable as well. The wall frames, insulation, and gypsum boards used in the composite walls replace the widely-used solid clay bricks in China's rural villages, reducing cement consumption and conserving non-renewable resources. Moreover, this lightweight and self-weight structure system can be constructed on sloping or poor-quality land, thereby saving land resources.
6. Beneficial for the industrialization of residential housing.
Cold-formed thin-walled steel structural assembly on-site, utilizing components that can be designed in modular systems, produced under factory standardization, and procured through the market, boasts excellent compatibility. This approach avoids the impact of on-site manual production on quality, facilitating the industrialization and commercialization of residential building development.
