W12 X 65 H Section Beam ASTM A36 Steel H Beam for Prefab House

W12x65 h shaped iron beam size specifications
Cross-section dimensions: height 307.85mm, leg width 304.8mm, waist thickness 9.91mm, leg thickness 15.37mm.
Weight per meter: about 96.66kg.
Naming rules: American standard H-shaped steel is represented by "W+number", where "W" represents width (inches) and numbers represent weight (pounds/foot). W12x65 corresponds to a width of 12 inches and a weight of 65 pounds/foot.
Cross-section characteristics: H-shaped structure, large section modulus, excellent bending and shear resistance, suitable for bearing complex loads.

Common materials of W12x65 h shaped beam
A36 steel h beam material: general low-carbon steel, moderate strength, suitable for conventional building structures.
A572GR50 h beam material: low-alloy steel, yield strength 50ksi (about 345MPa), suitable for medium load scenarios.
A992 material h beam: high-strength low-alloy steel, yield strength 50ksi, tensile strength 65ksi, suitable for large span or high load projects.
Implementation standards: in line with ASTM A36/A36M, ASTM A572, ASTM A992 and other American standards to ensure the standardization of chemical composition, mechanical properties and dimensional tolerances.

Application areas of W12x65 h section steel beam
Construction engineering: used for load-bearing structures such as beams, columns, trusses, etc., which can increase the effective use area by 4-6%.
Bridges and machinery: suitable for bridge supports, towers, and mechanical equipment frames because of their light weight and high stability.
Industrial facilities: factory steel structures, photovoltaic brackets and other scenes, fast construction speed, suitable for all-weather operations.

Advantages and characteristics of W12x65 h beam steel structure
Structural performance: 30-50% lighter than concrete structures, reducing foundation treatment costs, and excellent seismic performance.
Environmental protection and energy saving: dry construction has low noise, less residual solid waste, and a scrap steel recovery rate of up to 90%.
Economical: The construction period is shortened by 2-3 times, labor and material consumption is reduced, and the overall cost is saved by 10-15%.
