Australian Steel Fence Calculator

Estimate steel modules and posts from your supplier’s installed panel width. Keep cut panels, caps and optional sleeper lengths visible in the takeoff.

By Alish Gautam, Software Developer · Updated · Calculation methodology

Start with the editable example below. Dimensions retain their physical size when units change. Region sets currency labels without converting currencies; confirm entered quotes after changing region.

Fence layout

Run length includes gate openings. Gate offset is measured from the run start. Corner and straight connections share the preceding end post.

Project takeoff

Whole packages round up. Allowance is separate from purchased surplus. Prices omit labor, delivery, tax and other items unless explicitly entered.

No COLORBOND or LYSAGHT module width is universal. Enter the current product manual dimensions and confirm cut-panel, wind-region, sleeper and footing requirements.

How it works

Each uninterrupted span rounds its module count independently. Shared topology supplies physical post and cap quantities.

Assumptions and limitations

No COLORBOND or LYSAGHT module width is universal. Enter the current product manual dimensions and confirm cut-panel, wind-region, sleeper and footing requirements.

Whole packages round upward after the chosen allowance. Physical geometry and purchase reserve are separate. Manufacturer and project specifications override editable examples; the selected region does not establish a local code requirement.

Scope: Specified steel fence systems in non-cyclonic applications

Used for: Where to obtain installed module and footing specifications.

Does not establish: Universal steel panel width; Cyclonic-region suitability.

Use the current product document to verify numerical inputs. Use the current selected system manual; no branded panel dimension is hard-coded.
