Lightweight steel structures offer excellent earthquake and wind resistance. Their unique structural design allows buildings to remain stable and minimize damage during natural disasters such as earthquakes and high winds. This characteristic is crucial for enhancing housing safety and durability.
Lightweight steel structures exhibit excellent ductility, resulting in superior earthquake and wind resistance, with relatively minimal damage. Experimental data confirms that lightweight steel structures are two to three times more earthquake-resistant than traditional brick and wood structures. When brick and wood structures collapse in an earthquake, lightweight steel structures only experience recoverable bending deformation.
The ingenious design of lightweight steel keel structures allows their components to work together with the exterior wall panels to create a "skin effect," significantly enhancing the building's resistance to horizontal and vertical loads. The main structure of the building is assembled with bolts, ensuring its integrity and being firmly connected to the foundation, enabling it to withstand earthquakes up to a magnitude 9 earthquake. Light steel structures utilize hot-dip galvanized, high-strength, cold-rolled steel sheets with a galvanizing content of 185 grams per square meter, significantly extending the building's service life. Furthermore, light steel structures are lightweight and offer excellent wind and earthquake resistance, capable of withstanding a force 12 typhoon.
Light steel structures offer the advantages of low weight and low foundation costs, while also increasing the building's usable area. Their components have the smallest cross-sectional area among all building types, resulting in the lightest overall weight while maintaining the same load-bearing capacity. Furthermore, the use of lightweight, functional building materials reduces the overall weight to just 1/5-1/6 of that of brick-concrete structures. This reduces foundation requirements compared to traditional buildings, further reducing construction costs. Furthermore, the enclosure walls of light steel-framed structures are moderately thick, ranging from 14-20 cm, increasing the building's usable area by 10% compared to concrete structures. Furthermore, ultra-light steel-framed residential buildings effectively avoid the resource waste associated with fired bricks, while offering comparable economic performance to reinforced concrete structures.
The exterior walls of lightweight steel prefabricated houses are wrapped in extruded polystyrene or polyurethane, creating a continuous external insulation layer that effectively eliminates cold bridges and ensures excellent thermal insulation. A ventilated interlayer is cleverly designed between the exterior wall panels and the structural panels to insulate the building from extreme heat. This advanced external insulation method not only meets my country's latest building energy-saving standards but also effectively prevents cold-heat bridges. It also protects the building from moisture-induced deformation, mildew, and rust. Furthermore, the unique heat-reflecting and ventilated interlayer design further optimizes the building's thermal insulation performance, reducing indoor temperatures by 5-8°C.
Significant energy savings: Advanced technology reduces energy consumption by up to 65%-90%. Furthermore, the dry construction method significantly reduces water consumption, saving only 10% of traditional construction methods. Efficient resource utilization: 90% of building materials are recyclable, achieving material savings. Environmentally friendly building system: Utilizing recycled, non-polluting building materials, the building is environmentally friendly. Stable and Durable Structure: Structural components undergo a special galvanizing treatment to effectively prevent rust and ensure a 70-year structural lifespan. The use of new lightweight enclosure materials makes the building non-flammable, mold-resistant, and insect-resistant, making it even more durable.
Advanced sound insulation and vibration reduction technologies ensure the building meets national sound insulation standards. In particular, specialized reinforcements have been implemented in the 250-1000Hz frequency range, the most sensitive to the human ear, to create a quiet and comfortable living environment for residents. In summary, lightweight steel structures are not only environmentally friendly but also achieve new heights of comfort.
