The advantages of steel structure houses
1, the material strength is high, its light weight
Higher strength steel, elastic modulus is also high. Compared with concrete and wood, the density and yield strength ratio is relatively low, so under the same force in the steel structure of small cross-section, light weight, easy to transport and installation, suitable for large span, high load Structure.
2, steel toughness, good plasticity, material uniformity, high structural reliability
Suitable for the impact and dynamic load, has a good seismic performance. Steel internal organizational structure uniform, nearly isotropic homogeneous body. The actual working performance of steel structure is more in line with the calculation theory. So the steel structure reliability is high.
3, the high degree of steel structure manufacturing and installation of mechanization
Steel structural components to facilitate the factory manufacturing, site assembly. Factory mechanized manufacturing of steel structural components finished high precision, high production efficiency, site assembly speed, short duration. Steel structure is the highest degree of industrialization of a structure.
4, the steel structure sealing performance
As the welded structure can be completely sealed, can be made of air tightness, watertight are very good high-pressure vessels, large oil tanks, pressure pipelines.
5, heat-resistant steel is not fire
When the temperature below 150 ℃, the steel properties of change is very small. So the steel structure is suitable for the hot workshop, but the structure surface by about 150 ℃ heat radiation, must use the insulation board to protect. When the temperature is between 300 ℃ and 400 ℃, the strength and elastic modulus of the steel decrease obviously. When the temperature is about 600 ℃, the strength of the steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected by refractories to improve fire resistance.
6, steel corrosion resistance is poor
Especially in humid and corrosive medium environment, easy to rust. General steel structure to rust, galvanized or paint, and to regular maintenance. For offshore platform structures in seawater, special measures such as "zinc block anode protection" should be used to prevent corrosion.
7, low-carbon, energy saving, green, reusable
Steel construction demolition almost no construction waste, steel can be recycled.
