Steel Structure
The steel structure is a basic building structure consisting of steels. Steel has high strength, light weight, and great rigidity, so it is particularly suitable for construction of large-span, super-high-rise, and super-heavy buildings. The steel framework shows good homogeneous and isotropic properties. It is an ideal elastomer, which best meets the basic assumption of general engineering mechanics. With excellent ductility and toughness, it can achieve a large deformation and can well withstand dynamic loads.
The other characteristics are:
1. Light weight.
2. Eco-friendly, recyclable.
3. High stability, high earthquake resistance.
4. Highly industrialized.
5. Fast and accurate installation.
6. Large interior space.
7. Fire-retardant.
