When your project demands strong structural steel, LiYou Steel Structure Engineering Co., Ltd. delivers high-tensile, load-bearing solutions engineered for maximum stability and longevity. As an industry leader with CE, ISO, and SGS certifications, we provide heavy-duty structural steel components for industrial plants, high-rises, bridges, and mega-infrastructure projects worldwide.
✅ Exceptional Load-Bearing Capacity
Our strong structural steel is manufactured from high-grade Q355B/Q460B alloy, supporting heavy dynamic loads in:
Multi-story industrial facilities (e.g., Andritz Plant, 3,960-ton steel frame)
Long-span structures (e.g., Xiamen Metro maintenance depot, 2,360-ton roof system)
Seismic-resistant buildings (designed to GB 50011-2010 anti-earthquake standards)
✅ Precision Fabrication with Advanced Tech
CNC cutting (±1mm accuracy) and automatic submerged arc welding (SAW) for flawless joints
3D modeling (Tekla Structures) and FEA analysis to optimize stress distribution
✅ Corrosion & Fire Protection
Hot-dip galvanizing (up to 86μm coating) or intumescent paint (120min fire rating)
Complies with ISO 12944 anti-corrosion standards for harsh environments
✅ Proven Global Track Record
2360-ton steel framework for Foshan Metro Line 3 (35,770㎡)
970-ton workshop in Madagascar with 50m clear spans
Heavy Industrial – Power plants, oil & gas facilities
Large-Span Infrastructure – Airport terminals, stadiums
High-Rise Cores – Shear walls, transfer trusses (up to 300m buildings)
Material Traceability: Mill test certificates for all plates/beams
NDT Testing: 100% ultrasonic weld inspection
Load Testing: Prototype validation at 150% design capacity
