Rustproof Custom Metal Buildings Prefabricated Carbon Steel Structure ISO9001
Rust-Proof And Resilient Steel Structure Building For Warehouse Workshop Factory
Prefabricated steel structure building is becoming increasingly popular as a viable and affordable alternative to traditional brick or concrete structures. Designed to withstand various weather elements, all components are factory-made, pre-cut, pre-welded, pre-drilled, and pre-painted, requiring only bolt assembly on-site.
Steel structures have largely replaced traditional reinforced concrete in many countries due to their excellent characteristics: lightweight construction, large spans, material efficiency, cost-effectiveness, foundation savings, rapid construction cycles, and aesthetic appeal.
Product Specification
Xinguangzheng sources raw materials from China's largest steel factories, ensuring high-quality steel plates with rigorous inspection standards. Our steel structures meet three key requirements:
- Higher strength: Superior bearing capacity with smaller sections and lighter weight
- Better plasticity and toughness: Excellent resistance to brittle failure and dynamic loads
- Superior machining performance: Including welding capability, cold bending performance, and corrosion resistance
The following table serves as a reference. All products are fully customized to customer requirements:
| Structure | Part | Specification |
|---|
| Main Steel Frame | Column | Q235, Q355 Welded H Section Steel |
| Beam | Q235, Q355 Welded H Section Steel |
| Secondary Frame | Purlin | Q235 C and Z purlin |
| Knee Brace | Q235 Angle Steel |
| Tie Rod | Q235 Circular Steel Pipe |
| Brace | Q235 Round Bar |
| Maintenance System | Roof Panel | EPS Sandwich Panel, Glass Fiber Sandwich Panel, Rock Wool Sandwich Panel |
| Wall Panel | Sandwich Panel, Corrugated Steel Sheet |
| Accessories | Window | Aluminium Alloy Window, PVC Window, Sandwich Panel Window |
| Door | Sliding Sandwich Panel Door, Rolling Metal Door, Personal Door |

Features of Steel Structure Building
- Shortened construction period: Predefined materials reduce waste with standardized, prefabricated components for faster assembly
- Precision engineering: Computer-aided design ensures accurate fabrication and installation
- Cost efficiency: Lightweight materials reduce foundation requirements and transportation costs
- Flexible expansion: Easy extension capabilities with higher seismic resistance


Applications of Steel Structure Building
1. Portal Frame Structures
Traditional structural systems with rigid frame beams, columns, supports, and purlins. Ideal for industrial and commercial buildings including warehouses, workshops, and factories due to simple force transmission and rapid construction.
2. Frame Structures
Load-bearing systems with connected beams and columns, featuring non-load-bearing walls for enclosure. Commonly used in offices, malls, and exhibition halls.
3. Light Steel Structures
Cost-effective structures using round tubes, angle steel, and C-section purlins. Benefits include high factory production, minimal on-site work, and spacious interiors.
