What is a W Beam (Wide Flange H Beam)?

A W Beams (Wide Flange Beam) is a H Beam Structure with the following features:

Wide parallel flanges
Equal thickness
Strength with low weight

In contrast with conventional I-beams, W Beams have superior load bearing and rigidity properties, which makes them perfect for heavy-duty work.

Popular Materials for W Beam

Selecting the appropriate material is very important for the service life and the performance. Here are the most common types of materials to use:

Carbon Steel W Beam
Low-cost and easily accessible Great for welding and machining Ideal for every day building applications

ASTM A992 Wide Flange H Beam
High strength structural steel
Yield strength ≥ 345 MPa (50 ksi)
It is the most common choice for designing buildings and bridges in North America

ASTM A36 W Beam / ASTM A572 W Beam
A36: Common shape structural steel grades
A572: More strength, greatest for light weight structures

Q235 / Q355  H Beam (China Standard)
Q235: Mild steel for small Section
Q355: High strength substitute of A572

Standard Sizes of W Beam

W Beams are available in various sizes to suit diverse engineering needs.

Typical Dimensions:

Section Size Height (mm) Flange Width (mm) Thickness (mm) Weight (kg/m)
W100x50 100 50 4–6 9–12
