Beams - American Wide Flange Beams (2024)

Dimensions of American Wide Flange Beams ASTM A6 (or W-Beams) - Imperial units.

W-beams - wide flange beams - are stout, sturdy beams with wide flanges positioned perpendicularly to the web of the material giving them their characteristic shape and distinguishing them from I-beams.

Properties in imperial units of American Wide Flange Beams according ASTM A6 are indicated below.

The standard method for specifying the dimensions of a American Wide Flange Beam is for example W 6 x 25, which is 6 inches deep with a weight of 25 lb/ft.

I-shaped cross-section beams:

Britain : Universal Beams (UB) and Universal Columns (UC)
Europe : IPE. HE. HL. HD and other sections
US : Wide Flange (WF) and H sections

Insert W beams to your 3D Sketchup model with the Engineering ToolBox Sketchup Extension
