Steel structures use steel as the primary load-bearing component. They are widely used in various fields due to their advantages such as high strength, light weight, fast construction, and good seismic resistance. Its main use cases and application areas include:
Construction Engineering
1. Industrial Buildings - Factories: such as machining, metallurgy, and chemical plants
2. Warehouses: Large logistics and storage centers (such as high-bay warehouses and cold chain warehouses);
3. Civil Buildings - High-rise Buildings: Main frames of super-high-rise buildings (such as skyscrapers);
Public Buildings: Stadiums, exhibition halls, theaters, airport terminals, etc.
3. Residential Buildings: Steel-structured residential buildings
Transportation Infrastructure
1. Bridge Engineering - Long-span bridges - Railway/highway bridges
2. Rail Transit and Stations - High-speed rail stations, subway station concourses - Rail transit vehicles
Special Engineering and Equipment
1. Marine Engineering - Offshore Platforms: Main structures of oil drilling platforms (such as jackets and platform decks);
Shipbuilding
2. Hoisting and Construction Machinery - Cranes - Special vehicles
3. Large Equipment and Containers - Industrial storage tanks - Mechanical equipment frames
Other Special Scenarios
1. Temporary buildings: disaster relief housing, temporary exhibition halls, prefabricated buildings, etc.
2. Glass dome supports for large shopping malls
3. Energy engineering: wind turbine towers (made of rolled high-strength steel plates) and solar panels.

Cutting Process

1. Preparatory Work

Material inspection and verification
Drawing review and understanding

2. Selection of Suitable Cutting Methods

Flame cutting: Ideal for thick mild steel and low‑alloy steel, mainly used for rough machining.
Water jet cutting: Works with a wide range of materials, especially heat‑sensitive steel and high‑precision special‑shaped parts.

Welding Processing

This process bonds steel structural components at the joint using heat, pressure, or both (with filler metal where needed), creating a solid, unified structure. As a key connection method in steel fabrication, it is widely used in construction, bridges, machinery, shipbuilding and other fields, and directly determines the strength, stability and safety of steel structures.

Follow construction drawings or Welding Procedure Qualification Reports (PQR) to clearly define weld type, groove size, weld dimensions, welding position and quality grade.
