The 150PFC galvanised C post is the heavy-duty end/start post for taller retaining walls — a deeper C-channel section that accepts sleepers from one side for a clean termination. Hot-dip galvanised to AS/NZS 4680, in lengths from 2000 to 5800mm. 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.
Use the 150-series C post to terminate taller walls cleanly at ends and starts, with 150-series H and corner posts along the run. Pairs with the full concrete sleeper range.
Post length = retained height above ground plus embedment. For walls in this range, have post size, spacing and footing designed by an engineer (engineered walls over 1 metre, post sizing guide).
