Specification

Steel structure buildings are a modern alternative to traditional construction, utilizing steel beams, columns, and trusses connected by welding, bolts, or rivets. These structures are lightweight, durable, and quick to assemble, making them ideal for a variety of applications, from industrial facilities to high-rise buildings. Compared to traditional materials like concrete or wood, steel offers greater design flexibility, faster construction, and better resistance to environmental factors such as earthquakes and fire.
Types of Steel Structures
1. Portal Frame: Features a simple design and clear force transmission, commonly used in factories, warehouses, and commercial buildings.
2. Frame Structure: Offers flexibility for creating large spaces, often used in offices, shopping malls, and conference centers.
3. Truss Structure: Combines small tubes to form large components, ideal for stadiums, bridges, and towers.
4. Grid Structure: A lightweight, high-strength design with excellent seismic performance, suitable for gyms, exhibition halls, and aircraft hangars.
Advantages
- High strength-to-weight ratio for large spans and heights.  
- Faster construction due to prefabrication.  
- Sustainable and recyclable material.  
- Cost-effective in the long term with low maintenance.  
Steel structures are widely used in industrial, commercial, and public projects, providing a durable, efficient, and innovative solution for modern construction needs.
