Light weight, high strength, large span. Although the density of steel is greater than that of other building materials, due to its very high strength, the steel structure has a smaller weight under the same stress, so the structure of the steel structure plant can achieve a larger span.1. Short construction period and cost saving. Since all the components of the steel structure are made in advance in the factory, the assembly can be directly carried out on site, which greatly shortens the construction period. According to past experience, a 6,000 square meter building can be basically installed in about 40 days, thus saving time and labor costs. 3, high fire resistance. Generally speaking, the surface temperature of the steel is maintained within 150 ° C, which has little effect on the strength of the steel, so the steel structure is very suitable for hot workshops. If the temperature exceeds 150 ° C, it will have some impact on the strength, so if you want to maintain the strength, you can have special requirements for the steel structure. Take further insulation and fire resistance measures. 4, strong corrosion resistance. The steel structure has a certain corrosion resistance, and regular maintenance is required if it is in a humid environment, especially when it contains corrosive media. 5, strong sealing. Due to the tight internal structure of the steel, whether it is connected by welding, or connected with rivets or bolts, it can achieve a tight and leak-free sealing effect. 6. Affordable. The cost of steel structure is reasonable, and the advantages are much greater than those of concrete structure from the perspective of comprehensive economic benefits. 7, plasticity, toughness. Generally speaking, the steel structure will not break due to accidental overload or local overload, and the strong toughness makes the steel structure have a strong adaptability
