Rebar cutting optimizer

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.
