What are the steel structure works?

Steel structure engineering is a kind of construction engineering using steel as the main structural material, which has the advantages of high strength, rigidity, stability and durability. The following are some common steel structure works:

1. Steel frame building: This is one of the most common types of steel structure engineering, which is usually used in high-rise buildings, commercial buildings, public buildings and other fields. The main structure of steel frame building is composed of steel columns, steel beams and steel frames, which can be connected together by welding or bolts.

2. Steel plate structure: this structure uses steel plate as the main material, and forms steel plate wall, steel plate column, steel plate beam and other components through welding or bolt connection. Steel plate structures are usually used in large-span buildings, industrial buildings, warehouses and other fields.

3. Steel cable structure: This structure uses steel cable as the main structural material and forms a suspended structural system through tension. Steel cable structures are often used in bridges, overpasses, exhibition halls and large sports venues.

4. Steel pipe structure: this structure uses steel pipe as the main structural material, and forms steel pipe column, steel pipe beam, steel pipe frame and other components through welding or bolt connection. Steel tube structures are usually used in subway stations, airport terminals, gymnasiums and other fields.

5. Steel structure roof: this structure uses steel as the main material to form steel beams, steel arches, steel plates and other components of different shapes, which are used to cover the roof and facade of the building. Steel roof is usually used in large stadiums, cultural centers, commercial centers and other fields.

The above are common types of steel structure engineering, which have excellent performance and beautiful appearance, and are widely used in the field of modern architecture and infrastructure construction.
