TMT weight chart

Steel is ordered by weight but counted in pieces. Read the standard weights off the chart, or work out your own quantity below — any diameter from 8 mm to 32 mm.

Figures are indicative, calculated on the standard d² ÷ 162 formula used with IS 1786 bars. Actual delivered weight varies slightly by mill and by rolling tolerance, so treat this as a planning aid rather than a billing figure. We'll confirm exact weights when we quote.

Quick reference

Standard TMT bar weights

The numbers most people are actually looking for. A standard bar runs 12 metres.

Bars-per-tonne is rounded down, so ordering to that figure leaves you slightly under a tonne rather than over.
