1. Large space, light weight and small volume: compared with reinforced concrete and brick concrete, light steel structure can reduce weight by 15-30 times and volume by 2-5 times. Using the characteristics of high steel strength, the design can adopt large bay layout, so that the building plane can be reasonably separated, flexible and convenient, creating an open building. Steel tube or steel reinforced concrete columns (now there are few columns of pure steel structure in our country) make full use of the material characteristics of steel and concrete, improve the corresponding strength to reduce the section, and their compressive strength and lateral bending strength are 1.5 times higher than those of concrete columns, greatly increasing the ability of strong earthquake resistance and increasing the useful space. Compared with the traditional structure, it can better meet the requirements of large bay and flexible separation. And can improve the use of area rate 5% - 8%.

2、综合成本较低：钢材的稳定的供给造成价位的波动很小。使用薄壁轻钢结构的墙面可以保持好的平面。这也意味着当你在钉钉子的时候墙面不会反 弹和收缩破裂。因为材料可以预先切到需要的长度，所以在很大的程度上降低了浪费。另外，钢材的边料也是可以出

2. The comprehensive cost is low: the stable supply of steel causes little price fluctuation. The use of thin-walled light steel structure of the wall can maintain a good plane. It also means that when you're driving nails, the wall won't bounce and shrink and crack. Because the material can be cut to the required length in advance, the waste is greatly reduced. In addition, steel scrap can also be produced

售的，这样更是大大的降低了浪费。基础处理简便适用于广泛地质程度,基础部分比传统建筑要节约50%费用。合理墙体厚度使得用户的比一般现行建筑要多出8%左右，且因为施工快，缩短了资金的周转期，加 快了资金的流动速度，相应的降低了成本。

It can be sold, which greatly reduces the waste. The foundation treatment is simple, suitable for a wide range of geological degrees, and the cost of the foundation part is 50% less than that of the traditional building. Reasonable wall thickness makes the user's housing rate about 8% more than the general current building, and because the construction is fast, it shortens the capital turnover period, speeds up the capital flow speed, and correspondingly reduces the cost.

3、不破坏森林资源、清洁、可以循环利用：轻型钢结构住宅起源于美国，其背景是由于树木砍伐过渡而造成的森林破坏，进而导致整个全球环境恶化的问题成为全球注目的焦点。轻型钢结构住宅是以型钢骨架取代传统木造房屋的木骨架的建筑工法，使用的材料100%是钢材，各部材之间用螺钉和钉子连接，不使用任何焊 接及粘合剂。所以完全不用担心由于建筑过程中使用药剂等给人体造成的危害。此外建设工地也不会有大量灰尘及噪音等对周围环境造成的污染。

3. No damage to forest resources, clean environmental protection, recyclable: light steel structure housing originated in the United States, its background is due to the deforestation caused by the transition of tree felling, which leads to the global environmental degradation problem has become the focus of global attention. The light steel structure residence is a construction method of replacing the traditional wooden frame with steel frame. The materials used are 100% steel, and the parts are connected with screws and nails, without any welding and adhesive. Therefore, there is no need to worry about the harm to human body caused by the use of chemicals in the construction process. In addition, the construction site will not have a lot of dust and noise pollution to the surrounding environment.

4、施工快捷，节省劳动力：

4. Fast construction and labor saving:

轻型钢结构住宅的型材在工厂作大规模生产，骨架在工厂组装，现场拼装。轻型钢结构住宅与木结构类似。在相同的建筑要求的情况夏，薄壁轻钢结构熟练工人的劳动时间和成本比木结构要低上很多。薄壁轻钢结构的型材在工厂作大规模生产，骨架可在工厂组装，在工地安装。因为型材薄而轻，所以基本全部可以利用手工搭建完成。

The profile of light steel structure residence is produced on a large scale in the factory, and the skeleton is assembled in the factory and assembled on site. Light steel structure residence is similar to wood structure. In the case of the same construction requirements, the labor time and cost of skilled workers of thin-walled light steel structure is much lower than that of wood structure. The profile of thin-walled light steel structure is produced on a large scale in the factory, and the framework can be assembled in the factory and installed on site. Because the profile is thin and light, it can be built by hand.
