Steel is high strength, light weight, strong stiffness, therefore it is widely employed for the construction of large-span and super-high, super-heavy buildings; it is the ideal elastomer with perfect material homogeneity and isotropy which is most consistent with the basic assumption of general engineering mechanics;

Material with perfect plasticity, toughness and large deformation can receive dynamic loads well; short construction period; it is widely used in Industrials, so it is available with high degree of mechanization of specialized production; due to its high precision, high efficiency, good airtight , it can be used to build tanks, tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance.
