Difference between light steel and heavy steel in steel structure

With the development of modern industry, new steel structures have been widely used. With the urban construction and planning, many steel structures are erected in large quantities. In the design of steel structure, there are some differences between light steel and heavy steel, most of which are considered to be the weight of the structure itself. Here is a brief introduction:

1. Hoisting weight of crane: heavy steel structure ≥ 25t<light steel structure.

2. Steel consumption per square meter: heavy steel structure ≥ 50KG/M2<light steel structure.

3. Steel plate thickness of members: heavy steel structure ≥ 10MM<light steel structure.

4. Special application fields: petrochemical plant facilities, power plant plants, large-span stadiums, exhibition centers, high-rise or super high-rise steel structures must be heavy steel structures. Light roof, light exterior wall, light fingertip and other general workshops are usually light steel structure.

5. Reference to previous data: heavy steel structure>light steel structure, and the weight of larger members of heavy steel structure is much more obvious. Large span, structural form and eaves height are also important data for distinguishing light and heavy steel structures.

In fact, the difference between light steel and heavy steel is not the weight of the structure itself, but the weight of the enclosure materials they bear. They are the same in the concept of structural design, without difference.
