Reinforcing bar as it is stocked
| Reinforcing bar (AU/NZ/UK/EU) | 6.0, 12.0 m |
| Longer stock lengths | 9.0, 15.0, 18.0 m |
| Reinforcing bar (US) | 20, 40, 60 ft |
| Coil, decoiled to length (small sizes) | cut to order |
| Epoxy-coated and stainless | 6.0, 12.0 m |
| Your offcut rack | remnants you keep |
What each cutting method removes
| Hydraulic shear or cropper | 0 (nothing lost) |
| Bolt cutter or manual cutter | 0 (nothing lost) |
| Bandsaw | 0.8 to 1.5 mm |
| Abrasive cut-off disc | 1 to 3 mm |
| Circular rebar saw | 2 to 3 mm |
Most rebar is sheared or cropped, which removes no material, so kerf is genuinely zero. Set it to zero only if that is how you cut; a disc or a saw takes its slot out of every bar. More on kerf.
Cut it straight from the bar bending schedule
A bar bending schedule (BBS) is already a cut list: every bar mark, its shape code, cut length and quantity. Feed the cut lengths and quantities in and the optimiser nests them onto 6 m and 12 m stock for the fewest bars. The cut length is the straight length before bending, with the bending deductions already applied, so enter that, not the out-to-out dimensions off the shape.
Offcuts are stock, especially at these prices
Reinforcing steel is priced by weight, so a long offcut is money on the rack, not scrap. Enter what you have and the plan uses it, first or only when it saves a full bar, and set a minimum useful remnant so it stops leaving you 200 mm ends nobody can lap. On a big pour the reused offcuts add up to whole bars. More on offcut waste.
6 m or 12 m: it changes the waste and the handling
Twelve metre bar nests tighter and gives fewer laps, but it is heavier to handle and its offcuts are longer when they fall. Six metre bar is easier on site but wastes more on long members. Price both stock rows, run the job each way, and let the plan show you the trade in bars and in dollars instead of guessing at the merchant.
