What shape is designated L6" x 6" x 1"?

What shape is designated L6" x 6" x 1"?

• A. Equal leg L shape (Angle iron)
• B. Right angle corner
• C. Channel
• D. I-beam

Answer: (A)

Interpreting metal shape designations: the L indicates an L-shaped angle iron. The numbers tell you the size of the legs and the thickness: in L6x6x1, both legs are 6 inches long and the thickness is 1 inch, so it’s an equal-leg angle iron. This is different from a channel, which is C-shaped, or an I-beam, which is I-shaped with a web and flanges. A “right angle corner” isn’t a standard steel shape designation, so the given code clearly points to an equal-leg angle iron.
