Approximate weight

66 short tons

High confidence

About 6.6 short tons per cubic yard for solid steel at roughly 490 lb per cubic foot. A planning figure, not a specification. Confirm the density with your supplier before ordering by weight.

Conversion factor applied
6.6 short tons per cu yd

Steel is ordered and priced by weight, so a volume conversion is mostly a lifting and transport question — what a fabricated assembly weighs, whether a crane can take it, whether a load is within limits. Steel is roughly three times as dense as concrete, so volumes that look modest are extremely heavy: a single cubic yard is over six tons. That density is why steel sections are specified by weight per unit length rather than by dimension alone.

Add the equipment this sizes

This result is a specification — 66 short tons — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

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.

  • Typical bulk density used here: approximately 6.6 short tons per cubic yard
  • Density varies with moisture, grading and compaction — the supplier's ticket weight governs

Frequently asked questions

Why is steel specified by weight per foot?
Because weight is what governs both cost and structural capacity, and sections of the same nominal depth come in several weights. A W12x40 and a W12x65 are the same nominal depth and very different members.
How heavy is a cubic foot of steel?
About 490 pounds, roughly three times concrete. It is why a compact steel assembly can exceed a crane's capacity while looking easily liftable.
Does grade change the density?
Barely. Structural steel grades differ in strength rather than density, so a higher-grade section of the same size weighs essentially the same but carries more load.
