Steel Quantity Calculator

Work out reinforcement steel. Either add up the actual bars from the engineer’s drawing (diameter × length × number), or get a rough estimate from the concrete volume for early budgeting.

Unit weight: 0.889 kg per metre (d squared / 162).

Steel weight
0 kg

About 2.1 quintal. Steel is ordered by weight.

Add each bar size in turn (mix diameters as your bar bending schedule shows), then sum the weights and allow for laps, hooks and wastage.

Indicative only. The actual reinforcement — bar sizes, spacing, laps, cover and total weight — is set by a licensed structural engineer’s design and bar bending schedule to IS 456, not by a volume rule of thumb. Use this to cross-check or budget, never to build to.
