What are the properties of steel?
the steel has no leakage, easy to make closed structure.
1. steel high strength, plasticity, heat resistance, good toughness;
2. uniform steel material, high reliability;
3. the steel structure is simple to make, the construction period is short, with good assembly;
4. the steel has weldability;
5. the steel has no leakage, easy to make closed structure;
6. steel is closer to homogeneity and isotropy.
