Steel Weight
Pick a shape and size, enter the cut length and quantity, then add it to the takeoff list. Sizes show the imperial name first and the metric name after.

Rolled shapes and HSS use nominal weights from the AISC Shapes Database v15.0. Canadian (CISC) metric names are sometimes rounded, so W310x38.7 here is W310x39 on a Canadian mill list. Mechanical tube and plate are calculated from their dimensions.
