American Wide Flange Beam W30x108 W30x116
W30x108 steel and W30x116 h section steel are wide-flange H-section steels in the American Institute of Steel Construction (AISC) standard: W stands for "Wide Flange"; 30 stands for the nominal depth of the steel in inches, which is approximately 30 inches (762 mm); 108 and 116 stand for the weight of the steel in pounds per foot (lb/ft), i.e. W30x108 is 108 lb/ft and W30x116 is 116 lb/ft.

W30x116 is heavier than W30x108, mainly because the thickness of the flange and web is increased, resulting in a larger cross-sectional area and stronger load-bearing capacity; the moment of inertia and section modulus of W30x116 h section beam are larger, and the bending resistance and stiffness are better than W30x108 steel h column, which is suitable for higher load scenarios.
Production process of W30x108 W30x116 structural h beam
Hot rolling process: Usually through hot rolling forming, the steel billet is rolled into a specific cross-sectional shape at high temperature.
Surface quality: The surface flatness of hot-rolled steel is high and the residual stress is low, which is suitable for direct use in structural connections.
Material selection: Commonly used carbon steel (such as A36, A992), low-alloy high-strength steel can also be selected according to needs.
W30x108 W30x116 Structural steel h beam Application areas
Building structure: used as beams, columns or supporting members, commonly found in high-rise buildings, factories, stadiums, etc.
Bridge engineering: provides high load-bearing capacity and seismic resistance, suitable for bridge main beams or cross beams.
Machinery manufacturing: used for heavy equipment frames, crane rails, etc.
Energy industry: such as foundation structure support for wind power equipment.
