Light steel villa is also called light steel structure building (house and residence). Compared with the traditional brick concrete structure, it is structurally different. Of course, the practice is completely different. Through the house design, the whole house is prefabricated in the factory and assembled on site. The structural system of a villa is composed of tens of thousands of components, and the average error of each component is less than 2mm, which ensures the quality of the house, which can not be achieved by the traditional construction method. This building system is suitable for low rise buildings with less than 6 floors.

1、主体结构其主要材料是由热镀锌钢带经冷轧技术合成的轻钢龙骨，经过准确的计算加上辅件的支持与结合，起到合理的承载力，该结构有逐渐取代传统低层结构房屋的趋势。轻钢龙骨有两种材料，一种是镀锌，一种是镀铝锌。两者看起来一样，区别是镀铝锌造价比镀锌造价要高，镀铝锌强度高不生锈，镀锌会生锈。对于不懂的人来说，往往会以次充好。镀锌轻钢龙骨做装饰吊顶用的，是不能用来直接建房的。顺筑房屋采用的是上海宝钢钢带，镀铝锌轻钢龙骨，高强度钢材保证房屋整体支撑受力达到国家规范。

1. The main material of the main structure is the light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology. After accurate calculation and the support and combination of accessories, it has a reasonable bearing capacity. This structure has the trend of gradually replacing the traditional low-rise structure house. There are two materials for light steel keel, one is galvanized and the other is aluminized zinc. The two look the same. The difference is that the cost of aluminum zinc plating is higher than that of zinc plating. Aluminum zinc plating has high strength and does not rust. Zinc plating will rust. For people who don't understand, they often pass inferior goods off as good. Galvanized light steel keel is used for decorative ceiling, which can not be used for direct building. Shanghai Baosteel steel strip, aluminum zinc plated light steel keel and high-strength steel are used to ensure that the overall support stress of the house meets the national specifications.

2、轻钢别墅的楼面构造：轻钢别墅的楼面由冷弯薄壁型钢架或组合梁、结构板、防火板、保温棉、防水层、细石砼、地面面层连接件等组成。装饰时可铺设瓷砖或木地板，踩踏感觉与砖混效果一样。在这些轻质楼面上每平方米可承受316～365公斤的荷载。轻钢别墅的楼面结构体系重量仅为国内传统的混凝土楼板体系的四分之一到六分之一，但其楼面的结构高度将比普通混凝土板高100～120毫米。

2. Floor structure of light steel villa: the floor of light steel villa is composed of cold-formed thin-walled steel frame or composite beam, structural plate, fireproof board, thermal insulation cotton, waterproof layer, fine aggregate concrete, ground surface connectors, etc. Ceramic tile or wood floor can be laid during decoration, and the trampling effect is the same as that of brick concrete. On these lightweight floors, 316 ~ 365 kg load can be borne per square meter. The weight of the floor structure system of light steel villa is only one fourth to one sixth of that of the domestic traditional concrete floor system, but the floor structure height will be 100 ~ 120 mm higher than that of ordinary concrete slab.

3、轻钢别墅的屋面系统：轻钢别墅屋面系统是由屋架、结构OSB面板、防水层、轻型屋面瓦（彩石金属瓦或沥青瓦）组成的。轻钢结构的屋面，外观可以有多种组合。材料也有多种。在保障了防水这一技术的前提下，外观有了许多的选择方案。屋顶也可以装光伏发电系统。

3. Roof system of light steel villa: the roof system of light steel villa is composed of roof truss, structural OSB panel, waterproof layer and light roof tile (colored stone metal tile or asphalt tile). The roof of light steel structure can have a variety of combinations in appearance. There are many kinds of materials. On the premise of ensuring the waterproof technology, there are many options for appearance. Photovoltaic power generation system can also be installed on the roof.
