The galvanised steel 90° corner post is fabricated from two 100PFC C-channels factory-welded at a right angle — for wherever a retaining wall turns 90 degrees. Ideal for boundary corners, L-shaped and U-shaped walls. Hot-dip galvanised to AS/NZS 4680, in 800–2400mm. 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.
The corner post accepts concrete sleepers from both perpendicular directions, giving a clean right-angle return with no visible site-welded joins. Use with H-beam middle posts and C-channel end posts to complete the wall.
Post length = retained height above ground plus embedment (roughly double the wall height as a starting guide; confirm by engineering). See the steel post sizing guide.

For walls over 1.0m, reactive clay or surcharge loads, consult a structural engineer (engineered walls over 1 metre) and plan drainage.
