Advantages and disadvantages of steel structure

Hits：1969 Time：2017-4-19
　　In order to avoid the blind use of steel structure, steel structure for everyone to analyze the advantages and disadvantages of steel structure so that consumers can determine the value of use:

Advantage:
The sealing performance of the steel structure is good: because the welding structure can be completely sealed, the utility model can be used as a high pressure container with a high tightness, a good water tightness, a large oil tank, a pressure pipeline, etc..
High strength, light weight: high strength steel, high modulus of elasticity. Compared with the concrete and wood density and the ratio of yield strength is relatively low, and therefore under the same loading conditions section of steel structure is small, light weight, convenient transportation and installation, suitable for large span, height, weight bearing structure.
Defect:
Steel structure is not refractory: when the temperature is below 150 degrees Celsius, the nature of the steel is very small. Therefore, the steel structure is suitable for the hot workshop, but the surface of the structure should be protected by the thermal insulation plate when the heat radiation is about 150 degrees centigrade. When the temperature is 300 -400. The strength and elastic modulus of steel decreased significantly, when the temperature was about 600 DEG C, the strength of the steel tends to zero. In buildings with special needs for fire, steel structures must be protected by refractory materials to improve the fire resistance rating.
Corrosion resistance of steel structure is poor, especially in the environment of wet and corrosive medium. General steel structure to rust, zinc or paint, and regular maintenance. In order to prevent the corrosion of the offshore platform structure in seawater, special measures such as "zinc anode protection".
