H Beam Steel (Hot-Rolled Structural Sections)
H beam is a hot-rolled structural steel section characterized by its ‘H’-shaped cross-section with parallel flanges, designed to provide optimal load-bearing efficiency as beams and columns in construction.
Material
Structural Carbon Steel and High-Strength Low-Alloy (HSLA) Steel. Common steel grades include ASTM A36/A992, EN 10025-2 S235JR/S355JR, JIS G3101 SS400/SM400, GB/T 11263 Q235B/Q355B.
Model
Wide Flange Beam (e.g., W, HEA, HEB, IPB series), Standard I-Beam (e.g., S, IPN series).
Size
A wide range of standard sizes is available. Flange widths typically range from 100 mm to 400+ mm, with section heights from 100 mm to 1000+ mm.
Thickness
Flange and web thickness vary by specific section size, typically ranging from 6 mm to 40 mm.
Standard
ASTM A6/A6M (W, S shapes), EN 10034 (HEA, HEB, IPE series), JIS G3192 (H-shaped steel), GB/T 11263 (H, HW, HM, HN series).
MOQ
20 Metric Tons.
Delivery Time
Standard lead time is 4 to 7 weeks for mill orders; common sections may be available from stock with 2-3 week delivery.
Long Description
H beam, also commonly referred to as a wide flange beam, is a long product manufactured by hot rolling steel billets into a specific cross-sectional profile with two parallel flanges connected by a vertical web. This shape provides an excellent strength-to-weight ratio, with the flanges resisting bending moments and the web carrying shear forces. H beams are categorized into different series (e.g., light, medium, wide-flange) based on the proportional dimensions of the flange width to height. They are a fundamental component in structural engineering for framing systems, offering superior load-carrying capacity and stability compared to I-beams with sloped flanges. These sections are produced to precise dimensional and mechanical property standards, ensuring predictable performance in buildings, bridges, and industrial structures. They are supplied in standard lengths or cut-to-size.
Key Product Highlights
H beams provide exceptional bending strength and column stability due to their efficient cross-sectional geometry.
The product is hot-rolled in a single piece, ensuring consistent material properties throughout the section.
Available in a comprehensive range of standard sizes and weights per global dimensional standards.
Parallel flange surfaces simplify connection detailing and fabrication with other structural members.
The sections are suitable for a wide array of fabrication processes including welding, bolting, and drilling.
Product Advantages
Standardized dimensions and properties allow for efficient engineering design, procurement, and interoperability.
Hot-rolled production offers cost-effectiveness and material consistency for large-scale projects.
High structural efficiency leads to material savings, lighter overall structures, and reduced foundation costs.
Full material certification, including mill test certificates, provides traceability and ensures compliance with building codes.
Established global supply chains support timely delivery of both standard and non-standard sizes.
Industry Application
This section is primarily used as horizontal beams (girders, purlins) and vertical columns in the structural frames of buildings, bridges, mezzanines, platforms, and as support rails for heavy machinery.

Packaging & Surface Treatment
Beams are bundled by size and grade, secured with steel strapping at multiple points to prevent deformation during handling and transit. Protective caps are used on strapping edges. Bundles are often placed on wooden sleepers for stability. The standard surface condition is as-rolled with mill scale. Sections can be supplied shot blasted and painted with a shop primer (e.g., inorganic zinc) upon request for corrosion protection prior to fabrication.
