Steel structure building one-stop service. A choice, lifelong trust.

Steel structure is a structural form in which steel plates, hot-rolled, cold-bent or welded profiles are connected by connecting parts that can withstand and transfer loads. Steel structure system has the advantage of light weight, factory production, fast installation, short construction period, good seismic performance, investment recovery faster and environmental friendly. Comparing with a reinforced concrete structure, steel structure has unique advantages in the development of “high, large and light”. In the world, especially developed countries and regions, Steel structure has been reasonably and widely used in the field of building construction. Steel structure industry is usually divided into light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure.

1. Steel structure material strength is high, its own weight is light

The steel strength is high and the elastic modulus is high. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so the component cross-section of steel structure under the same force conditions is small, self-weighting, easy to transport and install, suitable for long span, high height, heavy load structure.

2. Steel toughness, good plasticity, uniform material, high structural reliability

Suitable for bearing impact and dynamic load, with good seismic performance. Steel internal structure uniform, nearly isotropic uniform body. The actual performance of steel structure accords with the calculation theory. So the reliability of steel structure is high.

3. High degree of mechanization in manufacturing and installation of steel structure

Steel structural components are easy to be manufactured in factories and assembled on site. Factory mechanized manufacturing of steel structure components finished products with high precision, high production efficiency, site assembly speed, short construction period. Steel structure is one of the most industrialized structures.

4. Good sealing performance of steel structure

Because the welded structure can be completely sealed, it can be made into high pressure vessels with good air tightness and water tightness, large oil pools, pressure pipes and so on.

5. Steel structure is heat resistant not fire resistant

When the temperature is below 150℃, the steel properties changes very little. Therefore, steel structure is suitable for hot workshop, but the surface of the structure is subjected to heat radiation of about 150℃, to be protected by heat insulation board. The temperature is between 300℃ and 400℃. The strength and elastic modulus of steel decreased significantly, and the strength of steel approached 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 rating.

6. Poor corrosion resistance of steel structure

Especially in wet and corrosive medium environment, easy to rust. General steel structure to rust, galvanized or coated, and to regular maintenance. The structure of ocean platform in seawater needs to be protected from corrosion by special measures such as “zinc block anode protection”.

7. low carbon, energy saving, green environmental protection, reusable

Demolition of steel structures produces little construction waste and steel can be recycled.
