What are The Characteristics of Steel Structure – ROYAL GROUP

1, high material strength, light weight. Steel has higher strength and higher elastic modulus. Compared with concrete and wood, its density and yield strength ratio is relatively low, so under the same stress conditions of steel structure members small section, light weight, easy to transport and installation, suitable for large span, high height, heavy bearing structure.
2, steel toughness, good plasticity, uniform material, high structural reliability. Suitable for bearing impact and dynamic load, with good seismic performance. The internal structure of steel is uniform, close to isotropic uniform. The actual performance of steel structure accords with the calculation theory. So the steel structure has high reliability.

3, steel structure manufacturing and installation of high degree of mechanization. The steel structure members are easy to assemble in factory and site. The factory mechanized manufacturing of finished steel structure components has high precision, high production efficiency, fast assembling speed and short construction period. Steel structure is one of the most industrialized structures.

4, the 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 vessels, large oil pools, pressure pipelines, etc.

5, steel structure heat resistance and no fire resistance, when the temperature is below 150°C, steel properties change very little. Therefore, steel structure is suitable for hot workshop, but the surface of the structure is protected by heat insulation plate when the heat radiation is about 150° C. The temperature is between 300° C and 400° C. The strength and elastic modulus of steel decreased significantly, and the strength of steel tended to zero when the temperature was about 600℃. In buildings with special fire protection requirements, steel structures must be protected by refractory materials to improve fire resistance grade.

6, the corrosion resistance of steel structure is poor, especially in the environment of wet and corrosive media, easy to rust. General steel structure to rust, galvanized or paint, and to regular maintenance. Special measures such as "zinc block anode protection" should be adopted to prevent corrosion of offshore platform structures in seawater.

7, low carbon, energy saving, green environmental protection, reusable. Demolition of steel structures produces little construction waste, and steel can be recycled.
