Do You Really Understand Steel Structures?

What is a steel structure?
Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

Uses of Steel Structures

The core purpose of steel structure is as a high-strength, lightweight and efficient structural system, which is widely used in super high-rise buildings, large-span venues, bridge projects, industrial plants, modular buildings and special infrastructure. The following are specific application scenarios：

1. Construction field
Super high-rise buildings
Steel structures break through height restrictions through high-strength steel (such as Q460GJ) and giant frame systems

‌Large-span spatial structure‌
Applicable to large-space scenes without columns such as stadiums and airports

2. Bridges and transportation engineering
Large bridges: such as cross-sea bridges and railway bridges, which use the high tensile strength and good seismic resistance of steel to improve safety.
Tunnels and underground engineering: Steel components are used for supporting structures or pipe segment connections to enhance the stability of underground space.
3. Industrial and energy facilities
Heavy-duty plant
Metallurgical workshops, power plants, etc. require large load scenarios, such as steelmaking furnace workshops and hydraulic press workshops.
Energy infrastructure
Oil depots, pipelines, and offshore oil production platforms use corrosion-resistant steel.
Nuclear power plant containment uses special steel components to ensure compression resistance.
4. Special structures
Movable/temporary buildings: temporary buildings on construction sites, exhibition halls, etc., which are easy to disassemble and reassemble.
Marine engineering: such as offshore drilling platforms, which require steel structure systems that are resistant to wind and waves and salt spray.
