Wide Flange Carbon Steel I Beam

Superior Load-Bearing Performance
The optimized I-shaped cross-section places material exactly where structural stress is concentrated. This increases the section modulus and moment of inertia, making our beams ideal for high-rise steel buildings, heavy industrial structures, bridge frameworks, and large-span construction projects.
Excellent Welding and Fabrication Capability
Our carbon steel wide flange beams are engineered for stable mechanical properties and reliable weldability. We offer comprehensive processing services to deliver installation-ready components:Precision cutting to required lengths ,Pre-drilled holes for bolted connections.
International Standard Compatibility
To meet diverse regional engineering requirements, Shanghai Xinyiheng strictly manufactures according to ASTM, EN, and JIS specifications, ensuring seamless integration into global supply chains. 

ASTM A992:
The industry standard for North American structural steel framing. Offers high yield strength, reliable performance, and excellent weldability for building frames and heavy structures.
ASTM A572 Grade 50:
A high-strength low-alloy steel providing greater strength than conventional carbon steel, allowing for reduced structural weight in demanding engineering applications.
ASTM A36:
A versatile, cost-effective structural steel grade known for its excellent weldability and broad application range.
EN S235JR / S355JR:
European structural steel grades widely used in industrial buildings and infrastructure. S355JR offers enhanced strength for heavier load-bearing applications.
