When choosing a steel space frame (steel grid structure) manufacturer, many buyers ask an important question:
Does the manufacturer need specific qualifications and technical capabilities?
The answer is yes—especially for large-scale, high-difficulty steel structure projects. Below, we explain why qualifications matter, what technical standards are required, and how a professional steel space frame manufacturer can ensure project safety, quality, and long-term performance.
1. Technical Difficulty Requirements
A qualified steel space frame processing factory must be capable of handling high-complexity and large-scale projects, including but not limited to:
High-Rise & Tower Steel Structures
- Height ≥ 100 meters
- Suitable for high-rise buildings, towers, and mast structures
Large-Span Steel Structures & Bridges
- Structural span ≥ 70 meters
- Ideal for stadiums, exhibition halls, terminals, and bridge steel components
Special Steel Structures
- Single project steel structure area ≥ 15,000 square meters
- Applicable to industrial plants, warehouses, and complex architectural steel systems
These requirements ensure the manufacturer has proven engineering experience, not just basic fabrication ability.
2. Production Equipment Capability
Advanced equipment is the backbone of high-quality steel space frame fabrication. A qualified manufacturer should be equipped with:
Cutting & Beveling Equipment
- 10 sets of semi-automatic gas cutting machines
- Professional beveling solutions for precision welding
Drilling Equipment (6–8 Sets)
- Radial drilling machines (Ø40mm and above)
- Gantry drilling machines (Ø40mm and above)
- Three-axis multi-spindle drilling machines (for H-beam, Ø30mm and above)
- CNC multi-axis profiling drilling machines
Forming & Straightening Equipment
- Hydraulic press (≥ 400 tons)
- H-beam straightening machine (plate thickness ≥ 40mm)
- Steel plate straightening machine (plate thickness ≥ 24mm)
- 2–3 complete straightening units
Bending & Cutting Equipment (4–5 Sets)
- Bending machines
- Pipe bending machines
- Edge planers
- Shearing machines
This equipment ensures high precision, strong load capacity, and stable structural performance.
3. Testing & Inspection Equipment
Strict quality control is essential for steel space frame safety. A professional manufacturer must be equipped with:
- 2 Ultrasonic Flaw Detectors
- 2 Magnetic Particle Testing Devices
- 1–2 High-Strength Bolt Axial Force Testers
- 1 Torque Tester
These inspection tools guarantee weld quality, bolt reliability, and compliance with international standards.
