1. H Beam Specifications Based on International Standards

W Series Specifications:
Specifications are based on "Cross-Section Height (inches) x Weight per Foot (pounds)." Key products include the W8x10 H Beam, W8x40 H Beam, and W16x89 H Beam. Among them, the W8x10 H Beam has a section height of 8 inches (about 203mm), a weight of 10 pounds per foot (about 14.88kg/m), a web thickness of 0.245 inches (about 6.22mm), and a flange width of 4.015 inches (about 102mm). It is suitable for photovoltaic brackets and secondary beams of small H Beam Steel Buildings; the W8x40 H Beam has a weight of 40 pounds per foot (about 59.54kg/m), a web thickness of 0.365 inches (about 9.27mm), and a flange width of 8.115 inches (about 206mm). The load-bearing capacity is doubled and it can be used as the main beam of medium-sized factories; the W16x89 H Beam has a section height of 16 inches (about 406mm), a weight of 89 pounds per foot (about 132.5kg/m), a web thickness of 0.485 inches (about 12.32mm), and a flange width of 10.315 inches (approximately 262 mm) is a heavy-duty specification designed specifically for long-span H-beam steel buildings and bridge load-bearing structures.

European standard specifications:
This covers two types: HEA H-beam and UPN H-beam. Specifications are indicated as "Section Height (mm) × Section Width (mm) × Web Thickness (mm) × Flange Thickness (mm)." HEA H beams are a representative of European wide-flange steel sections. For example, the HEA 100 specification has a section height of 100mm, a width of 100mm, a web thickness of 6mm, and a flange thickness of 8mm. Its theoretical weight is 16.7kg/m, combining lightweight and torsional resistance. They are commonly used in machinery bases and equipment frames. UPN H beams, on the other hand, have narrow-flange sections. For example, the UPN 100 has a section height of 100mm, a width of 50mm, a web thickness of 5mm, and a flange thickness of 7mm. Its theoretical weight is 8.6kg/m. Due to its compact cross-section, it is suitable for space-constrained steel structure nodes, such as curtain wall supports and small equipment columns.

2. H Beam Specifications Associated by Material

H Beam Q235b Specifications:
As a Chinese national standard low-carbon steel H-beam, the core specifications cover common sizes from H Beam 100 to H Beam 250. The H Beam 100 (cross-section: 100mm height, 100mm width, 6mm web, 8mm flange; theoretical weight: 17.2kg/m) and the H Beam 250 (cross-section: 250mm height, 250mm width, 9mm web, 14mm flange; theoretical weight: 63.8kg/m) offer a yield strength ≥ 235MPa, excellent weldability, and can be processed without preheating. They are primarily used for beams and columns in small and medium-sized domestic factories and multi-story steel-structured residential buildings, offering a highly cost-effective general-purpose specification.

ASTM H Beam Series Specifications:
Based on ASTM A36 H Beam and A992 Wide Flange H Beam. ASTM A36 H Beam has a yield strength of ≥250 MPa and is available in sizes from W6x9 to W24x192. The commonly used W10x33 (section height 10.31 inches × flange width 6.52 inches, weight 33 pounds per foot) is suitable for load-bearing structures in overseas industrial plants and warehouses. A992 Wide Flange H Beam, a high-toughness wide-flange steel section (the representative type of H Beam Wide Flange), has a yield strength of ≥345 MPa and is primarily available in sizes W12x65 (section height 12.19 inches × flange width 12.01 inches, weight 65 pounds per foot) and W14x90 (section height 14.31 inches × flange width 14.02 inches, weight 90 pounds per foot). It is designed for high-rise building frames and heavy crane beams, and can withstand dynamic loads and severe impacts.

3. Combining Customization and Universalization

Customize Carbon Steel H Beam Specifications:
Customizable cross-section height (50mm-1000mm), web/flange thickness (3mm-50mm), length (6m-30m), and surface treatment (galvanizing, anti-corrosion coating) are available. For example, corrosion-resistant carbon steel H-beams with a cross-section height of 500mm, a web thickness of 20mm, and a flange thickness of 30mm can be customized for offshore projects. For heavy equipment foundations, extra-wide flange H-beams with a length of 24m and a cross-section height of 800mm can be customized to meet non-standard load-bearing requirements.

General Steel H-Beam Specifications:
In addition to the aforementioned specifications, general specifications include the Hea Heb 150 (150mm × 150mm × 7mm × 10mm, theoretical weight 31.9kg/m) and the H Beam 300 (300mm × 300mm × 10mm × 15mm, theoretical weight 85.1kg/m). These are widely used in applications such as steel structure platforms, temporary support, and container frames, forming a comprehensive specification matrix ranging from light to heavy, and from standard to customized.
