The structure mainly made of steel is one of the main construction structure models.Steel is characterized by high strength, light self weight and large rigidity, so it is suitable for manufacturing long-span, super high and super heavy buildings. It has good homogeneity and isotropy of materials, and it is an aspiring elastic body, which is most suitable for the basic assumption of ordinary engineering mechanics. It has good plasticity and resistance, can have large deformation, and can well withstand dynamic load. The construction period is short;It has a high level of industrialization, can hold specialized production with a high level of mechanization, and can be used to manufacture gas tanks, oil tanks and transformers because of its high processing accuracy, high compliance and good tightness.Its disadvantage is poor fire resistance and corrosion resistance.

It is mainly used for heavy workshop’s load-bearing framework, power house structure, plate and shell structure, erect TV Tower and mast structure, bridge and warehouse and other long-span structures, high-rise and super high-rise buildings.In the future, high-strength steel should be studied to greatly improve its yield point strength; other new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel) and T-shaped steel, as well as profiled steel plate, to adapt to the need of large-span structure and super high-rise building.Steel structure is divided into light steel and heavy steel.There is no same standard for judgment, and many designers or project managers with resumes often fail to explain it thoroughly. They can think about it comprehensively with some data and judge it.

In addition, there is no heat bridge light steel structure system. steel structure construction itself is not energy-saving. This technology uses wonderful special connectors to solve the problem of cold and hot bridge construction; small truss structure makes the cable and the water pipe pass through the wall, and the construction and decoration are convenient; incomparable energy saving is the only construction system of 7-story residence built with cold-formed thin-walled steel.
