Areas marked as computed on the individual size pages are derived from the tabulated weight and steel density rather than read from the section table.

Need counts, not just sizes?

Upload a drawing set and SteelFlo puts a box on every steel label it finds — every structural tee on every page — ready to review and export as a bill of materials.
