Category: Construction

Mesh quantities depend on the specified bar spacing, cover and lap details. Those choices must come from the project drawings.

Enter the layout you have been given and review counts in both directions. Use the result to check quantities, with reinforcement design handled by the responsible engineer.

## Inputs and controls

* Measurement unit: Feet; Metres; Inches; Centimetres; Millimetres
* Slab length. Allowed range: 0.001 to 100000
* Slab width. Allowed range: 0.001 to 100000
* Specified edge cover (mm). Allowed range: 0 to 1000
* Spacing across width (mm). Allowed range: 1 to 3000
* Spacing across length (mm). Allowed range: 1 to 3000
* Specified bar diameter (mm). Allowed range: 1 to 100
* Layers. Allowed range: 1 to 10
* Extra lap length per bar (mm). Allowed range: 0 to 10000
* 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.

## How to use

* Choose measurement unit. Enter slab length, slab width, specified edge cover, spacing across width and spacing across length.

* Enter specified bar diameter, layers, extra lap length per bar, steel density, ordering allowance and steel quote.

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


## Why use this tool

A layout based count helps explain where the steel total comes from when checking a slab material schedule.


## Before relying on the result

Counts a specified layout. Bar size, cover, spacing and laps must come from your project drawings; this tool does not design reinforcement.


## Tool limitations

Counts a specified layout. Bar size, cover, spacing and laps must come from your project drawings; this tool does not design reinforcement.

## Questions

### Does the tool select safe bar spacing?

No. It counts an entered arrangement. It cannot establish the required bar diameter, spacing, cover or structural adequacy.

### What should I check before using Rebar Mesh Quantity Calculator?

Check Measurement unit, Slab length, Slab width and Specified edge cover. Use the exact units shown beside the controls and replace any example values with your own inputs.
