W10x12 W-type flange steel beam dimensions
W10x12 wide flange beam Model Meaning
W: Wide-Flange Beam, also known as H-beam, has a flange width similar to the web height, an "H"-shaped cross section, and better mechanical properties than ordinary I-beams.
10: Indicates that the cross-sectional height of the steel is approximately 10 inches (254mm) (the actual size may vary slightly depending on the standard or manufacturer).
12: Indicates that the weight per foot of length is approximately 12 pounds (lb/ft), converted to metric units:
Weight per meter ≈ 17.8 kg/m (12 lb/ft × 1.4882 = 17.86 kg/m).

W10x12 wide flange h beam Performance advantages
Cost-effective section: wide flange design makes the section inertia moment and section modulus larger, strong bending resistance, high material utilization rate, and can reduce the amount of steel used.
Easy to construct: easy to cut, drill and weld, suitable for industrial production and on-site assembly.
Versatility: can be used as beams, columns or supporting members, suitable for a variety of structural forms.
W10x12 w wide flange beam Application areas
Construction engineering: light frame structure (such as secondary beams and purlins of low-rise residential and commercial buildings); non-load-bearing walls or floor beams with small loads.
Industrial equipment: mechanical platforms, brackets or small equipment foundations.
Temporary structures: scaffolding, temporary supports or construction trestles.
Special scenarios: weight-sensitive structures (such as replacing traditional wooden beams in renovation projects).
