How Many 8mm Rebar Bars in a Tonne?

How Many 8mm Rebar Bars in a Tonne? The Quick Answer

At the standard 12 m stock length, one tonne of 8 mm rebar contains approximately 211 bars. This figure comes directly from the DIN 488 / EN 10080 nominal weight of 0.395 kg per metre:

• Mass per 12 m bar = 0.395 × 12 = 4.74 kg
• Bars per tonne = 1,000 ÷ 4.74 = ≈ 211 bars
• Total linear metres per tonne = 211 × 12 = ≈ 2,532 m

These numbers are the basis for ordering, site scheduling, and container-load calculations. The cross-sectional area of 8 mm bar is 50.3 mm², confirming the weight via the standard formula (d² × 0.00617).

Bars per Tonne at All Common Lengths

The number of bars per tonne changes with the supplied length. Here is the full matrix for 8 mm (0.395 kg/m):

Note that the total linear metres per tonne (≈ 2,532 m) is constant regardless of bar length — only the bar count changes. This is a useful cross-check when converting between ordering units.

Applying These Numbers to Ordering and Scheduling

Understanding bars-per-tonne for 8 mm rebar is essential in several scenarios:

• Bundle and crane capacity: A standard seaworthy bundle is typically around 2 tonnes. For 12 m bars, that is approximately 422 bars per bundle, each bar weighing 4.74 kg — a calculation relevant for lifting gear selection.
• Container loading: A 20 ft container can accommodate 12 m bars. Knowing the bar count per tonne helps verify that your declared quantity matches the container payload and gross weight documentation.
• Site scheduling: If your reinforcement schedule specifies a total linear metreage of 8 mm bar, divide by 2,532 to get the tonnage to order. Add your cutting waste allowance (typically 3–5 % for standard layouts).
• Mill Test Certificate traceability: Each MTC covers a heat/cast batch. Knowing the bar count per tonne helps your QA team cross-reference certificate coverage against delivered quantities.

Bars per Tonne Compared Across Diameters

It is also useful to compare 8 mm against nearby diameters. Lighter bars yield more bars per tonne; heavier bars yield fewer:
