Ø32 Rebar — Weight, Area & Ordering Numbers
Ribbed reinforcing bar B500 per EN 10080 / DIN 488
Ø32 rebar weighs 6.31 kg per meter — the nominal value every supplier and engineer uses, from the 804 mm² nominal cross-section at 7,850 kg/m³ (ribs are already accounted for: the nominal diameter is defined so that mass, not outside size, matches). A standard 12 m mill bar weighs 75.72 kg, so one tonne is about 13 bars or 158 meters.
These numbers are what you need to turn a cutting list in meters into an order in kilograms — and to check a delivery note against what actually arrived on the truck.

Frequently Asked Questions
How much does 32 mm rebar weigh per meter?
6.31 kg per meter (nominal, B500 per EN 10080). The quick site formula is d²/162: 32² / 162 ≈ 6.315 kg/m.
How many Ø32 bars are in a tonne?
About 13 bars of 12 m (75.72 kg each), or 26 bars of 6 m. One tonne of Ø32 is roughly 158 meters of bar.
What is the cross-section area of Ø32 rebar?
804 mm² nominal — the value used in reinforcement schedules. For example, 5 bars of Ø32 give 4,020 mm² of steel.
What is the US equivalent of Ø32 rebar?
The closest US bar is #10 (32.26 mm, 6.404 kg/m). US sizes are numbered in eighths of an inch, so exact matches are rare — check the required steel area, not just the diameter.
