A36 h beam W36x262 W36x282 W36x286 steel
"W36" series: indicates that the section height is 36 inches (about 914mm), and the suffix number is the weight (pounds/foot).
W36×262 h beam wide flange: weight 262 pounds/foot (about 390kg/m);
W36×282 w wide flange beam: weight 282 pounds/foot (about 420kg/m);
W36×286 w shape beam: weight 286 pounds/foot (about 426kg/m).
Material standard: A36 is a low-carbon structural steel that meets the ASTM A6/A36 standard and is suitable for construction and industrial load-bearing structures.
Flange width: about 350-400mm (depending on the model);
Web thickness: 25-35mm, flange thickness 20-30mm, cross-sectional area about 500-600cm²;
Moment of inertia: about 55,000-65,000cm⁴ (outstanding bending resistance).
Material performance characteristics of A36 structural steel h beam
Yield strength: ≥250MPa (36ksi), tensile strength 400-550MPa;
Elongation: ≥20%, excellent toughness, suitable for dynamic load scenarios;
Impact toughness: ≥27J (V-notch) at room temperature, ensuring stability in low temperature environment.
Low-carbon design: carbon content ≤0.25%, reducing the risk of cold cracks in welding;
Alloy ratio: manganese (0.80-1.20%), silicon (≤0.40%), improving work NMening ability.
Process advantages of A36 h beam steel structure
Hot rolling forming: uniform grain refinement, reducing internal residual stress; Weldability: low-hydrogen welding rods (such as E7018) are recommended, and welding heat input must be controlled within 2kJ/mm.
Core application areas of A36 structural h beam
Heavy building structure: used for super-high-rise building frames, large factory beams, supporting high concentrated loads; typical scenarios include main power plant buildings and oil tank support structures.
Bridge engineering: suitable for main beams and piers of railway bridges and highway bridges to meet the bending requirements of large spans. Industrial equipment manufacturing: As the base of metallurgical rolling mills and the segmented keel of ships, it can withstand long-term fatigue loads.
International compatibility of A36 h beam steel structure
1. Benchmarked with European standard S235JR and Japanese standard SS400, the mechanical properties and welding specifications are interchangeable;
2. Compared with the same series of high-strength steel (such as A572-50), A36 has lower cost and is suitable for non-extreme load scenarios.
