It depends on wall height and length. Taller walls need larger posts set at closer spacing, footed in concrete. H posts suit double-sided (post-and-panel) runs; C channel suits ends. Our team can spec posts to match your sleepers and wall height.

As a general guide, the footing depth is often around the same as the exposed wall height (for example, a 1 m wall may need roughly 1 m of post in a concrete footing), but this varies with soil and load — always follow the engineering for your wall. For walls over 1 metre in Victoria, get engineering advice and check permit requirements.

Yes. The galvanised steel is ready to use as-is, or you can paint / powder-coat it to match your landscape. Consult a coating specialist for the best prep.

Very. Hot-dip galvanised to AS/NZS 4680:2006, our posts resist corrosion for the long term in most environments.

No — the system is designed for straightforward, efficient install, suitable for pros and confident DIYers. Set the posts in concrete footings, then slot the sleepers in.

Minimal upkeep — occasionally check the drainage behind the wall and hose the posts down to remove dirt. Galvanised steel does the rest.
