Create itemwise schedules with bends, laps, and wastage. Review totals, unit weights, and cutting summaries. Export clear reports for site planning, procurement, and billing.
Enter multiple rebar items, then calculate total cut length, steel weight, and stock bar requirement.
Use this sample as a quick reference when filling actual bar marks, stirrups, slabs, or beam bars.
| Mark | Member | Shape | Dia (mm) | Qty | A (m) | B (m) | C (m) | Hooks | Laps | Waste % |
|---|---|---|---|---|---|---|---|---|---|---|
| B1 | Main Beam Bar | Straight | 16 | 24 | 5.60 | 0.00 | 0.00 | 0 | 1 × 50d | 3 |
| S1 | Beam Stirrup | Rectangular Stirrup | 10 | 110 | 0.25 | 0.45 | 0.00 | 2 × 9d | 0 | 5 |
| C1 | Column Tie | U-Bar | 12 | 32 | 0.90 | 0.30 | 0.30 | 2 × 10d | 0 | 3 |
A Bar Bending Schedule is a tabulated list of reinforcement bars showing mark, shape, size, cut length, quantity, and weight. It helps structural teams estimate steel accurately, reduce waste, and coordinate fabrication, site cutting, and procurement with clearer control over bar usage.
The d²/162 rule is a standard field shortcut for rebar weight per metre when diameter is in millimetres. It is widely used for fast estimation because it gives dependable results for scheduling, ordering, and checking steel quantities on drawings and site sheets.
Only add hook lengths when the bar detail actually includes end hooks or bends requiring extension. The calculator lets you enter hook count and hook factor separately, so straight bars can stay without hooks while stirrups, ties, and anchorage bars can include them.
Enter the number of laps for each bar item and the lap factor used by your project standard, such as 40d, 50d, or another requirement from the design notes. The calculator converts that allowance into metres and adds it to each affected bar length.
Yes. Choose the Rectangular Stirrup shape for closed ties, then fill side dimensions A and B. Add hook count and hook factor if needed. The tool will estimate cut length, wastage, total length, and steel weight for repeated stirrup or tie fabrication.
The stock bar estimate shows how many full commercial bars may be needed based on the reference stock length you enter, such as 12 metres. It is a planning figure for procurement and cutting strategy, not a replacement for an optimized cutting pattern.
Wastage accounts for cutting losses, trimming, handling damage, short offcuts, and site variation. Including a realistic percentage makes the schedule closer to practical procurement needs and reduces the chance of under-ordering steel for beams, slabs, columns, footings, or retaining members.
It is excellent for estimation, checking, and reporting, but final fabrication should still be verified against structural drawings, bending details, cover requirements, code provisions, and project notes. Always confirm lap, bend, and anchorage rules with the approved design before production begins.
