Where does this data come from?
The AISC Steel Construction Manual shape tables. Weight per foot and the published dimensions are nominal catalogue values — mill tolerances mean a delivered piece will not match exactly.

Weight per foot is the nominal catalogue value from the AISC shape tables. Mill tolerance means a delivered piece will not match it exactly — price the catalogue weight, and treat a scale ticket as the number that settles.

Questions
Why does a double angle appear twice?
A 2L is listed once for each orientation. 2L6X4X3/4LLBB has the long legs back to back and is 6 inches deep; 2L6X4X3/4SLBB is the same pair of angles turned, 4 inches deep. Same weight, different section.
Which leg is which on an angle?
The designation lists the long leg first: L8X4X1 has an 8-inch leg, a 4-inch leg and a 1-inch thickness. Each page labels them so there is nothing to infer.
Can I get a total weight from this?
Each page shows the weight of a run at common lengths. For a full takeoff with several shapes and a CSV out, use the steel weight calculator.
