Step 01
Start a project
Name it and set the floors, structure type and foundation type. It lands on your dashboard, organised into Foundation, Floors and Retaining-wall sections.
How it works
What you actually do — from project to schedule.
Step 02
Add a member
Pick a beam, column, slab, footing, pile, shear wall and more, then enter its size and rebar. Standard end bends, 50d laps and code cover are already built in.
Step 03
Watch the schedule build
The Bar Bending Schedule fills in as you type — length, nos and weight per bar, plus base steel, wastage, binding wire, grand total and a by-diameter breakdown. No calculate button.
Step 04
Save & export
It saves to your account and rolls up into project totals and kg/sqft. Export the whole schedule to Excel or PDF, and reopen to edit any time.

Two short videos on how Steel Calculator schedules steel and builds a whole project.
The old way vs Steel Calculator
Everyone knows the Excel version. Here's the difference.
Steel quantity in Excel
- Hours per project building and checking formulas by hand.
- A brand-new spreadsheet built from scratch every time.
- Six months on, the file is lost or the formulas have broken.
- No safe way to reopen and edit an old estimate.
- The take-off becomes the bottleneck billing and buying wait on.
Steel quantity here
- Dimensions in, full BBS and steel weight out — in clicks.
- Every project saved to your account automatically.
- Open any past project anytime, from any device.
- Edit a member and re-export to Excel or PDF in seconds.
- Quantities are instant — steel is never a dependency.
Everything you meet on site
Roughly fifteen structural members, scheduled to code.
From a single beam to a beam-and-slab raft — the members that make up real reinforced-concrete work, each with its own reinforcement logic built in.
Beam
Rectangular column
Circular column
One-way slab
Two-way slab
Mat / two-layer slab
Strip footing
Isolated footing
Combined footing
Raft (flat & beam-and-slab)
Pile
Pile cap
Shear wall
Retaining wall
Sunshade
Grade beam
Pedestal
Show, don't tell
The schedule you'd issue — computed for you.
A worked example for one beam. On screen you also get total length and unit weight per line, plus wastage and binding-wire totals for every member — then export the whole schedule to Excel or a branded PDF.
Example output · Bar Bending Schedule
Beam B1 · 300 × 450 mm · span 6.00 m
| Bar description | Dia (mm) | Nos | Cut (m) | Wt (kg) |
|---|---|---|---|---|
| Top — straight | 16 | 2 | 6.42 | 20.3 |
| Top — extra at supports | 16 | 2 | 2.15 | 6.8 |
| Bottom — straight | 20 | 3 | 6.60 | 48.9 |
| Bottom — curtailed | 20 | 1 | 4.80 | 11.9 |
| Stirrups @150 c/c | 8 | 40 | 1.42 | 22.4 |
| Base steel | — | 48 | — | 110.3 |
Base steel 110.3 kg
Wastage +3% 3.3 kg
Binding wire 1.1 kg
Grand total 114.7 kg
Portfolio analytics
Steel intensity you can benchmark and quote from.
Every project reports its total steel and its steel intensity — kg/sqft or kg/sqm. Roll it up across the portfolio to see intensity by structure type, catch outliers, and price new work from your own history.
Framed
4.5 kg/sqft
RCC frame — columns, beams and slabs carrying the load.
Load bearing
2.8 kg/sqft
Masonry walls carry gravity load; steel mostly in slabs and lintels.
Partially framed & load bearing
3.6 kg/sqft
A mix of frame and bearing walls across the structure.
Figures shown are illustrative. Break the same view down by foundation type — Piling · Strip · Isolated · Raft · Combined · Mixed — to compare like with like across your projects.
