Structural Steel Tonnage Aggregator

Calculate total steel tonnage from total linear footage and average weight per unit length.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Total steel tonnage

24.8 tons

High confidence
Total mass
49604.01 lb

For the dimensions entered, expect a total steel tonnage of 22.5 metric tons. Note that total linear length of members sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. Set for United States against IRC 2024. The market selector changes both the units and the code cited.

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Why does this use an average weight per meter instead of listing individual sections?
This calculator aggregates a takeoff into a single tonnage figure once you already have the total linear length and a quantity-weighted average weight per meter — it doesn't itemize individual shapes; use the individual shape weight calculators (I-beam, channel, angle, HSS, pipe) for that.
How do I get an accurate average weight per meter for a mixed steel package?
Weight each section's per-meter weight by its share of total linear length (e.g. weighted by length, not by piece count), so heavier, longer members appropriately dominate the average.
Does the result include connection material like plates, bolts, and welds?
No — this only tallies the linear steel members you enter. Add plate, bolt, and other connection material weights separately for a complete tonnage estimate.
