Strong Structural Steel

Strong Structural Steel – Unmatched Strength & Durability for Heavy-Duty Construction

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.

Why Choose Our Strong Structural Steel?

✅ 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

Key Applications

 Heavy Industrial – Power plants, oil & gas facilities
 Large-Span Infrastructure – Airport terminals, stadiums
