Steel is bought by the kilogram, and a fabrication spec often runs to dozens of items in different lengths. Nesting them right across 6 m and 12 m stock is the difference between 3% and 10% waste — the optimizer finds it in seconds.
▶ Open the calculatorEnter your stock lengths (typically 6 m and 12 m) and the items from the spec. The tool combines cuts across bars with minimal waste and produces a ready plan for the bandsaw — bar by bar, with each bar's remnant.
Enter a price per meter and the calculator shows the value of the material, the used portion and the waste. Scrap stops being a percentage on screen and becomes a line in the quote.
A bandsaw takes 1.5–2 mm per cut, an abrasive saw 2–3 mm — the “Kerf” field accounts for it on every cut. “Min remnant” separates pieces good for stiffeners, plates and flanges from the scrap pile.

Yes — anything cut to length: hot-rolled beams, cold-formed hollow sections, angles, flats, round and rectangular tube. To the tool, every item is a length.
Most commonly 6 m and 12 m; wholesalers also cut agreed fixed lengths. The calculator accepts any — including remnants from previous jobs.
On a typical fabrication spec, the gap between manual and optimized nesting is on the order of 3–8% of tonnage — at steel prices, that pays back on the first order.
