What are the characteristics and advantages of steel structure?
Steel structure is a structure composed of steel materials and is one of the main types of building structure. The structure is mainly composed of steel beams, steel columns, steel truss and other components made of steel and steel plates. Welds, bolts, or rivets are usually connected between components or components. Because of its light weight and simple construction, it is widely used in large factory buildings, venues, super high -rise, bridge and other fields.

Characteristic
1. The material strength is high, and the weight is light
Steel strength is high and the elastic modulus is also high. Compared with concrete and wood, the ratio of its density and yield strength is relatively low, so the section of the component of the steel structure under the same force is small, light and light, easy to transport and installation, suitable for large span, high height, loading weight Structure.
2. Steel toughness, good plasticity, uniform material, high structure reliability
Suitable for impact and power load, with good shock resistance. The tissue structure of the steel is uniform, and the same as the same as the same as the same. The actual work performance of the steel structure is more in line with the theory of computing. So the steel structure is highly reliable.
3. High mechanization of steel structure manufacturing and installation
Steel structure components are convenient for factories and construction sites. Factory mechanization manufacturing steel structure components have high accuracy, high production efficiency, fast construction speed, and short construction period. Steel structure is a structure with the highest level of industrialization.
4. Good steel structure sealing performance
Because the welding structure can be completely sealed, high -pressure containers, large oil pools, pressure pipelines, etc. with good water tightness and water density.
5. Steel structure, heat resistance, refractory refractory
When the temperature is below 150 ° C, the nature of steel changes very little. Therefore, the steel structure is suitable for the heat workshop, but when the structure surface is about 150 ° C, the heat radiation should be protected. When the temperature is 300 ° C -400 ° C. The strength and elastic modulus of the steel decrease significantly. When the temperature is about 600 ° C, the strength of the steel tends to zero. In buildings with special fire protection requirements, the steel structure must be used to protect the refractory material to improve the refractory level.
6. Poor corrosion resistance of steel structure
Especially in the environment of humid and corrosive media, it is easy to rust. Generally, the steel structure should be removed, galvan or coatings, and regular maintenance should be maintained. For the structure of the marine platform in the seawater, special measures such as "zinc block anode protection" need to be used to prevent corrosion.
7. Low -carbon, energy saving, green and environmentally friendly, can be reused
The demolition of steel structure buildings will hardly produce construction waste, and steel can be recycled and reuse.
