# Steel Bar Weight Calculator

Build a bar schedule with lengths, quantities and weights.

Category: Construction

A steel order is easier to check when bar lengths and quantities are written down before the total weight is calculated.

Build the schedule from the specified diameters and cut lengths. Keep bends, supplier tolerances and delivery weights in mind when comparing the theoretical total with a quote.

## Inputs and controls

* Measurement unit: Feet; Metres; Inches; Centimetres; Millimetres
* Steel density (kg/m³). Allowed range: 1000 to 20000
* Ordering allowance (%). Allowed range: 0 to 100. Added once to the measured requirement.
* Steel quote (PKR / kg). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.
* Reference
* Diameter (mm). Allowed range: 1 to 100
* Cut length. Allowed range: 0.001 to 100000
* Number of bars. Allowed range: 1 to 100000

## How to use

* Choose measurement unit. Enter steel density and ordering allowance.

* Enter steel quote.

* Add the entries in bar schedule as separate rows. Include reference, diameter, cut length and number of bars for each row.

* Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

Individual bar rows give you a traceable weight calculation rather than one unexplained steel allowance for the entire building.


## Before relying on the result

Nominal cylindrical steel weight. Diameter tolerances, bends and supplier weights can differ.


## Tool limitations

Nominal cylindrical steel weight. Diameter tolerances, bends and supplier weights can differ.

## Questions

### Is the calculated weight a delivery guarantee?

No. It uses nominal cylindrical dimensions. Actual diameter tolerances, bends and supplier measurement methods can produce a different delivered weight.

### What should I check before using Steel Bar Weight Calculator?

Check Measurement unit, Steel density, Ordering allowance and Steel quote. Use the exact units shown beside the controls and replace any example values with your own inputs.
