I & H Beam

Structural I-Beam & H-Beam Steel | High Load Bearing Beams

I-beam and H-beam are among the most important structural steel products used worldwide in civil engineering, industrial construction, and manufacturing. Named after their distinctive cross-sectional shapes resembling the letters “I” and “H,” these beams are designed to provide exceptional load-bearing capacity and structural stability.

H-beams, also known as “wide flange beams,” feature wider flanges than I-beams, which provide superior resistance to bending and torsion. This makes H-beams particularly suitable for heavy-duty structures such as high-rise buildings, bridges, and large-scale industrial facilities. I-beams, with their more compact design, are commonly used in medium-scale projects and fabrication works where cost-effectiveness and structural efficiency are equally important.

Our hot-rolled I-beams and H-beams are produced with steel grades such as Q235, Q345, ect. we can meet the performance requirements of a wide variety of projects. These beams offer excellent weldability, machinability, and durability, while optional surface treatments (galvanizing, painting, or anti-rust coating) provide long-lasting protection against corrosion.

Applications

Construction & Structural Frameworks
Used in high-rise buildings, large-span structures, and industrial plants for primary load-bearing beams, floor systems, and roof frameworks. H-beams with wider flanges are preferred where higher bending resistance and seismic performance are required.

Infrastructure & Major Engineering Projects
Applied in bridge girders, overpasses, tunnels, and power station structures where long-term strength and durability under heavy loads are essential.

Machinery, Vehicles & Industrial Manufacturing
Used for equipment platforms, machine bases, factory frameworks, and heavy fabrication where standardized sizes and strong axial/bending capacity are needed.

Transportation, Port & Railway Facilities
Employed in railway bridges, port structures, terminal buildings, and highway supports that require high load capacity and resistance to dynamic stresses.

General Fabrication & Heavy-Duty Applications
Commonly used in fabrication shops for trailers, cranes, structural reinforcements, and custom large components; suitable for outdoor use after appropriate corrosion protection.
