Hebei steel structure Co.,ltd

1, high material strength, light weight Steel strength is higher, elastic modulus is also high.

Compared with concrete and wood, the ratio of density to yield strength is relatively low, so the component section of steel structure under the same stress condition is small, light weight, easy to transport and install, suitable for large span, high height, heavy bearing structure.

2, steel toughness, good plasticity, uniform material, high structural reliability Suitable for shock and dynamic load, with good seismic performance. The internal tissue structure of steel is uniform and close to isotropic homogenization body. The actual working performance of steel structure is more in line with the calculation theory.

So the steel structure has high reliability.

3, Steel structure manufacturing and installation mechanization degree is high Steel structure components are easy to manufacture in the factory, site assembly. Factory mechanized manufacturing steel structure components finished products with high precision, high production efficiency, fast site assembly speed, short duration.

Steel structure is one of the most industrialized structures.

4, steel structure sealing performance is good

Because the welding structure can be completely sealed, can be made into air tightness, water tightness are very good high-pressure containers, large oil pools, pressure pipes and so on.

5, steel structure heat-resistant non-refractory When the temperature is below 150 ℃, the properties of the steel change very little. Therefore, the steel structure is suitable for hot workshop, but when the structure surface is affected by thermal radiation of about 150 ℃, it should be protected by insulating plate. When the temperature is 300℃-400℃, the strength and elastic modulus of the steel decrease significantly, and when the temperature is around 600 ℃, the strength of the steel tends to zero.

In buildings with special fire protection needs, steel structures must be protected by refractory materials to improve fire resistance levels.

6. Poor corrosion resistance of steel structure Especially in the humid and corrosive media environment, easy to rust. General steel structure to remove rust, galvanized or paint, and to be regularly maintained.

For the structure of ocean platform in seawater, special measures such as "zinc block anode protection" need to be used to prevent corrosion.

7, low carbon, energy saving, green environmental protection, reusable The demolition of steel structure buildings will hardly produce construction waste, and steel can be recycled and reused.
