█基本特点
Basic characteristics
以冷弯薄壁型钢构件为基本结构骨架，以新型结构板材为结构体系，配以其它保温、装饰材料，经工厂集成生产和现场装配而成的房屋建筑体系。
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.
该系统采用冷弯薄壁型钢结构体系，具有截面尺寸小、自重轻等特点，比传统建筑的使用面积提高5～10%，显著地降低了基础造价；独特的墙体承重体系，使建筑造型富于轻灵动感，提高了室内布局的灵活性；低碳型建筑材料，使建筑耐久性更好、结构更，具有良好的抗震、防火、热工、隔声性能，是一种型绿色建筑体系。
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.
█ 适用范围
Applicable scope
超轻钢住宅体系适用于1～6层（不含地下室，檐口高度应不大于12m）的新建、改建、扩建建筑。但是冷弯薄壁型钢骨架与钢结构、钢筋混凝土结构的混合结构建筑物的层数不受此限。

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.
