The galvanised 100UC H post with Reo has a reinforcing bar welded to the base — it strengthens the footing connection and makes installation easier, and is sized directly by the height of wall you're building (to 2000mm). Hot-dip galvanised to AS/NZS 4680. Australian-made, delivered Australia-wide by Retaining Walls Direct.
Written and product-checked by the Retaining Walls Direct team — supplying steel-post retaining wall systems across Australia. Last updated: June 2026.
This is the standard H-beam middle post for the concrete sleeper system, with a welded reinforcing-bar base for a stronger, simpler concrete footing. Select the variant by your finished wall height — the post length already allows for embedment. Browse the full steel post range for end and corner posts.
Choose the variant that matches your finished wall height (400–2000mm) — the supplied post includes the embedment allowance for a standard footing. Posts sit at sleeper-length centres. Confirm post size, spacing and footing with an engineer for taller walls, clay soils or surcharge loads (post sizing guide).
