1. Product Overview
H section steel (H-beam) features H-shaped cross-section integrally hot rolled with parallel equal-thickness flanges and vertical web. Different from ordinary I-beam, its flat flanges deliver uniform stress distribution, strong bending rigidity and lighter self-weight. It is divided into hot rolled H beam and welded H beam.Compliant with Chinese standard GB/T 11263-2024 Hot Rolled H Section Steel & Split T Section Steel. We can produce to international standards including ASTM A36/A572 Gr50, EN S235JR/S355JR, JIS G3192, DIN for global export.Material grades cover low carbon carbon steel, high strength low alloy steel, medium carbon quality structural steel and alloy structural steel, stainless steel excluded.
Four Classification Codes of H Section Steel
HW Wide Flange H Beam: Flange width close to section height, ultra-high lateral stiffness, mainly for load-bearing columns
HM Medium Flange H Beam: Universal for beams & columns, mainstream profile for workshops and multi-story frames
HN Narrow Flange H Beam: Narrow flanges with strong vertical bending resistance, used as main & secondary floor beams
HT Thin Wall H Beam: Lightweight material for light workshops, platforms and small supports
2. Material Grade Classification
2.1 General Low Carbon H Beam (Civil Steel Structure)
Grades: Q235B, SS400, S235JR, ASTM A36Features: Good ductility, easy cutting & welding, cost-effective for workshops, office buildings and light equipment supports
2.2 High Strength Low Alloy H Beam (Heavy Load, Low Temperature & Long-Span Projects)
Grades: Q355B/C/D, S355JR, A572 Gr50, Q460Features: High yield strength, excellent low-temperature impact toughness, over 30% higher load capacity, suitable for bridges, super high-rises, wind power supports, cold storage and severe cold region projects
2.3 Medium Carbon Structural H Beam (Heavy Machinery Base & Machining Parts)
Grades: 20#, 35#, 45#, S45C, 1045Features: Balanced strength, available for quenching & tempering heat treatment, for large machine bases, heavy equipment supports and flange blanks
2.4 Alloy Structural H Beam (Wear-Resistant Heavy Construction Machinery)
Grades: 40Cr, 65Mn, 60Si2MnFeatures: Good hardenability, anti-fatigue & wear resistance, dedicated for mining machinery and heavy-duty fixed supports
3. Surface Treatment
Hot Rolled Black Surface H Beam: Original mill scale without coating, primary material for steel structure main body, secondary painting & hot galvanizing substrate
Hot-Dipped Galvanized H Beam (GI): Fully pickled & degreased before galvanizing, thick firmly bonded zinc layer with superior salt spray resistance, for PV supports, outdoor steel structures, coastal docks and power frames
Anti-Rust Oil Coated H Beam: Temporary rust protection for stock storage and ocean container transport, low cost
Painted H Beam: Customizable anti-corrosion topcoat (grey/red/yellow etc.), integrated beauty & rust prevention for indoor exposed structural members
Shot Blasted H Beam: Mill scale removed, clean surface to greatly improve adhesion for welding and painting
4. Dimension Specifications
4.1 Size Marking Format
Marking rule: H Height × Flange Width × Web Thickness t1 × Flange Thickness t2, example: HN400×200×8×13
Section Height H: 100–900mm
Flange Width B: 100–450mm
Web Thickness t1: 6–38mm
Flange Thickness t2: 6–30mm
4.2 Standard Fixed Length
Standard delivery lengths: 6m,9m,12m; customized multiple lengths 1–18m and unlimited cutting length available, support segmented processing for extra-long profiles
4.3 Supply Form
Only straight bars bundled, no coils; single bundle weight 2–6 MT, standard 12m bundle approx 3–4 MT, extra-large sizes can be shipped single bare pieces
4.4 Theoretical Weight Formula
Cross Section Area S = t1×(H−2t2) + 2×B×t2 + 0.858×r² (r = inner fillet radius)Weight per meter (kg/m) = Cross Section Area S × 0.00785
5. Main Mechanical Properties
| Grade | Min Yield ReL (MPa) | Tensile Rm (MPa) | Min Elongation A (%) | Typical Application |
|---|---|---|---|---|

7. Production Process
Hot Rolled H Beam
Billet high-temperature heating → Continuous forming rolling via universal mill → Precise thickness control for web & flange → Hot straightening to eliminate bending & torsion → Fixed-length saw cutting → Surface cleaning → Sampling test for dimension & mechanical property → Bundling & warehousing
Welded H Beam
Steel plate blanking cutting → Web & flange assembly + submerged arc automatic welding → Weld seam flaw detection → Deformation correction → Shot blasting rust removal → Anti-corrosion treatment → Cutting & inspection for storage
8. Export Standard Packing, Storage & Transportation
8.1 Bundling Standard
All straight bars fastened with multiple heavy-duty galvanized steel strips: 4 strips for short lengths, 6 strips for standard 12m, 8–9 strips for extra-long profiles, tight bundles to prevent sliding. Metal tag attached to each bundle with bilingual grade, size, heat number, weight & applicable standard; waterproof PVC label supplied for export. Full PE film wrapping & anti-rust oil spraying available for large profiles to resist salt fog & moisture during ocean shipment.
8.2 Storage Rules
Stack on raised ventilated yard with steel sleeper isolation from ground; keep galvanized H beam away from long-term rain & water accumulation; separate storage by grade, model and length to avoid batch mixing.
8.3 Transportation
