High material strength and light weight
The steel has a high strength and a high modulus of elasticity. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the steel structure has a small cross section, light weight, easy transportation and installation, and is suitable for large span, high height, and heavy bearing capacity.
Steel toughness, good plasticity, uniform material, high structural reliability
The steel structure is suitable for impact and dynamic loads, with good seismic performance. The internal structure of the steel is uniform and close to the isotropic homogeneous body. The actual working performance of the prefabricated steel structure is in line with the calculation theory. Therefore, the steel structure has high reliability.
