Definition of Steel Structure
Steel structure is the primary load-bearing system in construction, made from steel components with high load-bearing capacity, flexibility, and cost efficiency. It is the top choice for large-scale projects such as factories, industrial buildings, bridges, and heavy steel structure projects.
Steel structures are widely used not only in industrial construction but also in civil engineering projects such as high-rise buildings, shopping centers, and stadiums.
Common Types of Steel Structures
- Steel Frames: Includes beams, columns, trusses, braces, and purlins, applied in factories and pre-engineered buildings.
- Grid and Dome Structures: Used for sports stadiums, exhibition centers, and conference halls.
- Steel Bridges: Includes girder bridges, cable-stayed bridges, truss bridges, suspension bridges, and arch bridges.
- Prestressed Structures: Enhancing load capacity, used in transportation infrastructure and high-rise buildings.
Advantages of Steel Structures
- Fast Construction: Prefabricated steel components reduce on-site construction time.
- Large Span Capability: Creates spacious areas without excessive columns, ideal for warehouses and factories.
- Aesthetic Appeal: Modern, flexible design suitable for contemporary architecture.
- Quality Assurance: Manufactured under strict quality control standards.
- Flexible Use: Easy to disassemble, expand, or repurpose when needed.
Materials and Features of Steel Structures
- Structural Steel Profiles: Includes U, I, L, H, and tubular steel, widely used in heavy steel structures.
- Steel Plates: Used for primary load-bearing components.
- Common Steel Grades: SS400, Q345, SM490, known for high tensile strength, suitable for various projects.
- Galvanization: Two common methods—electroplating and hot-dip galvanizing—enhance durability and corrosion resistance.
Fabrication and Quality Control Process
- Fabrication: Includes cutting, drilling, welding, and assembly according to design drawings.
- Surface Treatment: Shot blasting, deburring, primer coating, and final coating for steel protection.
- Quality Inspection: Advanced testing methods such as ultrasonic testing, magnetic particle testing, and hardness measurement ensure high-quality standards.
Applications of Steel Structures
- Pre-engineered Buildings: Widely used in industrial warehouses and factories.
- Steel Bridges: Ensuring durability and high load-bearing capacity for transportation infrastructure.
- High-rise Buildings: Reducing structural weight and improving construction efficiency.
- Infrastructure Projects: Applied in overpasses, ports, airports, and railway stations.
