1, high material strength, light weight
The steel strength is high, and the elastic modulus is also high. Compared to concrete and wood, the ratio of its density and yield strength is relatively low, so the components of the steel structure under the same force conditions are small, light, easy to transport and mount, suitable for span, high, high high, bearing weight Structure.
2, steel toughness, good plasticity, uniform material, high structural reliability Suitable for impact and power load, have good seismic properties. The internal tissue structure in the steel material is uniform, close to the isotropic homogeneous body. The actual working performance of the steel structure is compared to the theory of calculation. Therefore, the steel Custom Steel Fabrication structure is reliable.
3, steel structure manufacturing installation mechanization level
Steel structural member facilitates manufacturing, construction site assembly. Factory mechanization manufacturing steel structural components are high, high production efficiency, fast construction site, short construction period. Steel structure is a structure with the highest level of industrialization.
4, steel structure sealing performance Since the welding structure can be completely sealed, a high-pressure container, a large oil cell, pressure pipeline, etc. .
5, steel structure heat-resistant non-fire
When the temperature is below 150 ° C, the nature of the steel is small. Therefore, the steel structure is suitable for hot workshop, but the structural surface is protected by a heat absorbing plate when the surface of the structure is about 150 ° C. When the temperature is at 300 ° C to 400 ° C. Steel strength and elastic modulus decrease, and the temperature of the steel tends to zero when the temperature is about 600 ° C. In buildings with special fire prevention requirements, the steel structure must be protected by refractory materials to improve the fire resistance.
6, steel structure corrosion resistance In particular, in a humid and corrosive medium, it is easy to rust. General steel structures should be removed, galvanized or coated, and to be maintained regularly. For the ocean platform structure in seawater, special measures such as \”zinc block anode protection\” need to be used to corrosion corrosion.
7, low carbon, energy saving, green environmental protection, reusable
Steel structural building is hardly generated, and steel can be recycled.
