Steel structure characteristic

1. Stainless steel plate ductility, good plastic deformation, material symmetry, high credibility of the structure, suitable for bearing impact driving force load, with excellent seismic grade performance. Stainless steel plate internal structure well-proportioned, tend to anisotropic uniform protoplasm. The performance of steel structure in concrete work accords with basic theory of calculation. Therefore, the steel structure has high credibility.

2. High compressive strength of raw materials, light weight, high bolt strength, high elastic mold. Compared with concrete and wood, its relative density and tensile strength ratio is relatively low, so under the same bearing force standard steel structure component cross section is small, light weight, conducive to transportation and installation, suitable for large span, high width ratio, heavy bearing structure.

3. Steel structure sealing performance is good, because welding structure can ensure complete sealing, sealing, tightness are very good pressure vessels, large and medium-sized oil pools, two types of pressure vessels, etc..

4. Steel structure high temperature resistance is not fire, when the temperature is below 150℃, stainless steel plate characteristics change little. Therefore, steel structure is suitable for thermal production workshop, but when the surface of the structure is subjected to thermal radiation up and down 150℃, insulation materials should be used in many aspects of maintenance. The temperature is between 300℃ and 400℃. Bolt strength and elastic die are significantly reduced, the temperature at 600℃ left, stainless steel plate compressive strength tends to zero. In the construction with unique fire safety requirements, the steel structure must be maintained with fire-resistant insulation materials in many aspects to improve the fire rating.

5. The corrosion resistance of steel structure is poor, especially in the natural environment of wet and cold and corrosive substances, it is very easy to rust. General steel structure to rust treatment, hot dip galvanized or architectural paint, and to maintain. For the structure of deep-sea service platform in the sea, special measures such as "zinc block anode protection" should be adopted to provide corrosion resistance.

6. Steel structure production, manufacturing and installation machinery automation level is high, steel structure components help in the processing plant production and manufacturing, construction site assembly. Processing plant machinery automation production of steel structure components manufactured products with high precision, high productivity, construction site assembly faster, tight schedule. Steel structure is the most modernized structure.
