A36/A572GR50/A992 W8x48 W8x58 W8x67 Wide Flange Beam
h profile steel web and flange thickness
W8×67 has the thickest web (14.5mm) and the thickest flange (23.7mm), and has the strongest shear and bending resistance; W8×48 has thinner web and flange (10.2mm/17.4mm) and is lighter.
h beam profile section height
W8×67 has the largest height (229mm), which is more suitable for large-span structures than W8×58 (222mm) and W8×48 (216mm).
A36 steel beam h material mechanical properties
General properties: yield strength ≥250MPa, tensile strength 400-550MPa, elongation ≥20%, meeting the needs of ordinary building structures.
Local strength difference: Due to its greater thickness, the actual shear strength of W8×67 (about 145MPa) is higher than that of W8×48 (about 120MPa).
Applicable scenarios of h type steel beam
W8×48: Main beams of medium-sized industrial plants and supporting structures of medium-sized bridges, which need to balance weight and load-bearing capacity.
W8×58: Heavy-loaded building frames (such as high-rise steel structures) and port machinery bases, which require high bending stiffness.
W8×67: Ultra-heavy-loaded projects (large-span venue roofs, heavy equipment platforms), which require extremely high stability and shear resistance.
