H Steel Product Specification

H steel is an efficient section profile with an H-shaped cross-section, composed of web and flange. Its flanges feature parallel inner and outer surfaces and right-angle ends. Compared with I-beam, it offers superior bending resistance, lighter self-weight and easier installation, and is widely applied in construction, bridges, industrial equipment and other fields.

1. Basic Definition & Aliases

Official Name: H Beam (Parallel Flange I-beam)
Aliases: Wide Flange I-beam, Universal Beam, H Steel
Core Features: Optimized cross-sectional area distribution, reasonable strength-to-weight ratio and balanced bending performance in all directions.

2. Product Classification & Codes (GB/T 11263-2017)

2.1 Classification by Flange Width

HW (Wide Flange): Flange width is approximately equal to section height. Mainly used for steel columns and frames, e.g. HW400×400.
HM (Medium Flange): Flange width accounts for 1/2 to 2/3 of section height. Suitable for workshop beams and columns, e.g. HM300×200.
HN (Narrow Flange): Flange width is about half of section height. Applied to beams and purlins, e.g. HN200×100.
HP (Pile Type): Extra wide and thick flanges, designed for steel piles and supporting structures.

2.2 Classification by Production Process

Hot Rolled H Steel: Rolled from heated steel billets with high dimensional accuracy and uniform performance. It is the mainstream product.
Welded H Steel: Fabricated by cutting and welding steel plates. Custom special sections are available, ideal for variable cross-section components.

3. Specifications & Marking Method

3.1 Marking Rule

H (Height, mm) × B (Flange Width, mm) × t1 (Web Thickness, mm) × t2 (Flange Thickness, mm)

Example: HN350×175×7×11

H = 350mm (Section Height)
B = 175mm (Flange Width)
t1 = 7mm (Web Thickness)
t2 = 11mm (Flange Thickness)

3.2 Common Sizes & Theoretical Weight

Model	Height × Width (mm)	Web Thickness (mm)	Flange Thickness (mm)	Theoretical Weight (kg/m)
HW100×100	100×100	6	8	16.9
HM250×175	244×175	7	11	44.1
HN350×175	350×175	7	11	49.4
HW400×400	400×400	13	21	172

4. Material Standard & Chemical Composition

4.1 Common Grades

Q235B: Ordinary carbon structural steel, yield strength ≥ 235MPa, for general structures.
Q355B/C/D/E: High-strength low-alloy steel, yield strength ≥ 355MPa, for load-bearing structures and low-temperature environments.
Weathering Steel (Q355NH): Excellent corrosion resistance, used for coastal and outdoor projects.

4.2 Executive Standards

GB/T 11263-2017 Hot rolled H and cut T section steel
GB/T 700 Carbon structural steels
GB/T 1591 High strength low alloy structural steels

5. Mechanical Properties (Typical Values)

Yield Strength: Q235B ≥ 235MPa; Q355B ≥ 355MPa
Tensile Strength: 370–500MPa (Q235B); 470–630MPa (Q355B)
Elongation: ≥ 20%
Bending Property: No cracks after 180° cold bending test

6. Production Process

Hot Rolling: Heat steel billet to 1200–1300℃, roll through multiple roller passes, then conduct straightening and sawing after cooling. It features high precision and cost efficiency.
Welding Process: Steel plate cutting → assembly → welding (submerged arc welding / high-frequency welding) → straightening. Applicable for extra-large sizes and customized variable sections.

7. Product Advantages

Excellent Section Performance: Parallel flanges with right angles, superior moment of inertia on X and Y axes, outstanding bending and torsion resistance.
Light Weight & Material Saving: Saves 15%–20% steel compared with I-beam and reduces foundation load.
Convenient Construction: Easy for welding and bolt connection. Dry construction shortens construction period and lowers noise.
Good Seismic Performance: Steel structure features good ductility and is not easy to fracture under seismic load, suitable for high-rise buildings.
Durable & Nice Appearance: Smooth surface available for direct painting. Long service life after anti-corrosion treatment.

8. Application Scope

Steel Building Structure: Beams and columns for high-rise buildings, factory frames, portal rigid frames and floor beams.
Bridge Engineering: Highway & railway bridges, footbridges and temporary supports.
Industrial Facilities: Equipment supports, pipe brackets, furnace frames and mine supports.
Municipal & Marine Engineering: Steel piles, wharf trestles, offshore platforms and photovoltaic brackets.

9. Delivery Status & Packaging

Delivery Condition: Supplied in hot rolled state. Surface free from scale, cracks and laminations.
Packaging: Loose bundling, 2–5 tons per bundle. Model, specification, material grade and batch number are marked on both ends.
Quality Documents: Material certificate, product qualification certificate and mechanical property test report are provided together with goods.

10. Selection Guide

Load-bearing Columns: Prioritize HW series (e.g. HW300×300) for excellent bidirectional bending resistance.
Frame Beams: Choose HM / HN series (e.g. HM488×300, HN400×200) to balance strength and weight.
Long-span & Heavy-load Projects: Adopt Q355B grade to reduce section size.
Corrosive Environment: Select weathering steel or hot-dip galvanized treatment to extend service life.
