90 Degree Corner Steel Posts for Retaining Walls — Canberra & ACT

Our 90-degree corner posts are purpose-engineered to accept concrete sleepers on both faces at a true right angle, delivering a clean, structurally sound corner without site fabrication or welding. Built to handle Canberra's frost conditions, reactive clay soils, and extreme temperature swings, these posts are hot-dip galvanised and ready to install. Retaining Walls Direct has supplied ACT builders, landscapers, and homeowners for many years.
