█基本特點
Basic characteristics
以冷彎薄壁型鋼構件為基本結構骨架，以新型結構板材為結構體系，配以其它保溫、裝飾材料，經工廠集成生產和現場裝配而成的房屋建筑體系。
A building system consisting of cold-formed thin-walled steel components as the basic structural framework, new structural panels as the structural system, and other insulation and decorative materials, which are integrated and assembled in the factory and on-site.
該系統采用冷彎薄壁型鋼結構體系，具有截面尺寸小、自重輕等特點，比傳統建筑的使用面積提高5～10%，顯著地降低了基礎造價；獨特的墻體承重體系，使建筑造型富于輕靈動感，提高了室內布局的靈活性；低碳環保型建筑材料，使建筑耐久性更好、結構更安全，具有良好的抗震、防火、熱工、隔聲性能，是一種節能型綠色建筑體系。
The system adopts a cold-formed thin-walled steel structure system, which has the characteristics of small cross-sectional size and light self weight, increasing the usage area by 5-10% compared to traditional buildings, significantly reducing the basic cost; The unique wall load-bearing system endows the building with a light and dynamic design, improving the flexibility of indoor layout; Low carbon and environmentally friendly building materials make buildings more durable, structurally safer, and have good seismic, fire, thermal, and sound insulation properties. They are an efficient and energy-saving green building system.
█ 適用范圍
Applicable scope
超輕鋼住宅體系適用于1～6層（不含地下室，檐口高度應不大于12m）的新建、改建、擴建建筑。但是冷彎薄壁型鋼骨架與鋼結構、鋼筋混凝土結構的混合結構建筑物的層數不受此限。

The ultra light steel residential system is suitable for new, renovated, and expanded buildings with 1-6 floors (excluding basements, and the eaves height should not exceed 12m). However, the number of floors of buildings with a mixed structure of cold-formed thin-walled steel skeleton, steel structure, and reinforced concrete structure is not limited by this limit.
