H-beam Detailed Product Description
1. Product Definition and Overview
H-beam is a high-efficiency section steel with an H-shaped cross-section, consisting of upper and lower parallel flanges and a vertical web. Its inner and outer flange surfaces are parallel with right-angle ends, so it is also called wide-flange I-beam.
Core Advantages
Optimized cross-section distribution, high strength-to-weight ratio, excellent bending and torsion resistance, light self-weight, good seismic performance, convenient construction and low overall cost.
Executive Standards
Hot-rolled H-beam complies with GB/T 11263-2017; welded H-beam complies with YB/T 5307 or customized engineering standards.
2. Classification, Models and Specifications
2.1 Classification by Flange Width (National Standard Hot-rolled)
HW (Wide Flange H-beam): Height is approximately equal to flange width, mainly used for load-bearing columns and building frames, e.g. HW200×200×8×12.
HM (Medium Flange H-beam): Flange width is about half of the height, widely applied for general beams and columns, e.g. HM250×175×7×11.
HN (Narrow Flange H-beam): Flange width is less than half of the height, ideal for main beams and crane beams, e.g. HN300×150×6×9.
HT (Thin-walled H-beam): Suitable for light enclosure and secondary structures.
2.2 Classification by Production Process
Hot-rolled H-beam: Manufactured by high-temperature rolling of steel billets. It features good overall performance, high dimensional accuracy and uniform mechanical properties. Its specifications follow national standards, and it is commonly used for workshop columns, floor main beams and other heavy-duty structures.
Welded H-beam: Produced by cutting steel plates and adopting submerged arc welding. The dimensions are customizable with height ranging from 200mm to 3000mm. Strict welding quality control is required. It is applied to long-span bridges, super high-rise columns and components under special loads.
2.3 Specification Expression (Unit: mm)
Code + Height (H) × Flange Width (B) × Web Thickness (d) × Flange Thickness (t), e.g. HW100×100×6×8.
Common Materials
Q235B, Q355B (Q345B), Q420B, SM490, SS400.
3. Dimensions and Theoretical Weight (Common Hot-rolled Types)
| Model | H×B×d×t (mm) | Theoretical Weight (kg/m) | Cross-sectional Area (cm²) |
|---|---|---|---|
| HW100×100 | 100×100×6×8 | 24.2 | 30.8 |
| HW200×200 | 200×200×8×12 | 50.5 | 64.2 |
| HM250×175 | 250×175×7×11 | 40.2 | 51.2 |
| HN300×150 | 300×150×6×9 | 37.3 | 47.5 |
| HN400×200 | 400×200×8×13 | 66.0 | 84.1 |
4. Mechanical Properties (Typical for Q355B)
Yield Strength (ReH): ≥ 355 MPa
Tensile Strength (Rm): 470–630 MPa
Elongation (A): ≥ 20%
Impact Toughness (-20℃): ≥ 34 J
Section Moment of Inertia (Ix): 30% to 50% higher than that of I-beams with the same weight, delivering greatly improved bending resistance.
5. Application Scope
Steel Structure Construction: Load-bearing columns of high-rise and super high-rise buildings, main frame beams of workshops, crane beams, roof and floor beams.
Industry and Municipal Engineering: Equipment supports, pipe brackets, blast furnace frames, mine supports, long-span bridges and offshore platforms.
Underground Engineering: Steel piles, foundation pit supports and tunnel bracings.
6. Production and Packaging
Length: Conventional length of hot-rolled products is 6m, 9m and 12m; welded products can be customized from 12m to 24m.
Surface Treatment: Raw steel, anti-rust paint coating, galvanization and shot blasting.
Packaging: Bundled, each bundle weighs 2 to 5 tons. Product ends are painted and labeled with specifications, material grade and batch number.
7. Quality Assurance
Complete material certificates, product quality certificates and non-destructive testing reports (UT/MT) are provided.
Dimensional tolerance: Height and width ±2mm, thickness ±0.5mm, length ±50mm.
Surface quality: Free from cracks, scabs, folds and excessive rust.
