Look up the weight of a real AISC rolled shape, or calculate plate, round bar, or square/rect bar weight — for estimates, freight planning, and erection sequencing.
Shape lookup: total_lb = weight_per_foot × length_ft × quantity. Weight-per-foot values are sourced from the AISC Shapes Database — 1,660 real designations (W, HP, S, M, C, MC, L, WT, MT, ST, HSS, Pipe), facts only, re-presented in our own format, not a copy of AISC's published tables. Plate mode: weight_lb = t × w × l × 0.2836. Round bar: (π/4)d² × L × 0.2836. Square/rect bar: a × b × L × 0.2836. Plate/round/rect modes assume carbon steel density 490 lb/ft³ (0.2836 lb/in³) — a labeled assumption; stainless and aluminum differ. Nominal weights only — excludes connections, plates, bolts, and coatings.
Type an AISC designation and a length and it returns the piece weight and the total for the quantity, in pounds and tons, using the weight-per-foot from the AISC Shapes Database. Plate, round bar and square or rectangular bar have their own modes that work from dimensions and a carbon-steel density of 490 lb/ft³. It is the number you need for a freight call, a crane pick, or a quick sanity check on a bill of material.
Two W12X26 beams at 30 ft: 26 lb/ft × 30 ft = 780 lb each, 1,560 lb for the pair, 0.78 tons. A 1/2" × 24" × 96" plate: 0.5 × 24 × 96 × 0.2836 = 327 lb.
Nominal reference only. Verify designation, dimensions, and properties against the official AISC Steel Construction Manual before fabrication/detailing. This tool is an estimating aid, not a design tool or shipping certification.
