Steel Bar & Rebar Cutting Optimizer
NEWInput your steel bar stock length (default 12m), add your required cut lengths with quantities, and get an optimized cutting plan that minimizes scrap and saves money on reinforcement steel.
How to use Steel Bar Cutting Optimizer
- Verify or adjust the stock bar length (default 12000mm for standard rebar).
- Add each required cut length and quantity — click Add Piece for each different length.
- Adjust the kerf to match your cutting tool (5mm default for abrasive saws).
- Click Optimize to generate the cutting plan and review scrap percentage.
What is Steel Bar Cutting Optimizer?
This tool is preset for steel reinforcement bar (rebar) cutting, using a default 12000mm (12m) stock length — the standard for construction-grade rebar. The First-Fit Decreasing algorithm sorts your required cuts from longest to shortest and packs them into the minimum number of bars.
Blade kerf is preset to 5mm to account for the abrasive cut-off saw or bandsaw typically used on rebar. The visual cutting layout shows each steel bar as a horizontal strip with color-coded cut segments, making it easy to transfer the plan to your cutting station or bar bending schedule.
FAQ
- Why is the default stock length 12 meters?
- 12 meters (12000mm) is the standard length for construction-grade rebar in most countries. However, rebar is also available in 6m, 9m, and custom lengths. Adjust the stock length field to match what your supplier provides.
- Does this account for bar bending deductions?
- This tool optimizes straight cuts only (cutting bars to required lengths). For bending schedules, use our Rebar Calculator which handles bend deductions, lap lengths, and development lengths. Use this tool first to minimize scrap, then apply bending allowances separately.
- Can I use this for structural steel sections?
- Yes. Set the stock length to match your steel sections (e.g. 6000mm for standard I-beams) and adjust kerf for your cutting method. The 1D Cutting Optimizer (general-purpose version) also works for this.
