The standard method for specifying the dimensions of a American Standard Steel Channels is like C 5 x 9. which is a beam *5 inches* deep with a weight *9 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
