45 Degree Corner Steel Post Sydney NSW

45 Degree Corner Steel Posts for Retaining Walls — Sydney & NSW

When your retaining wall needs to change direction at a 45-degree angle, a standard post simply won't do the job. Our 45-degree corner steel posts are purpose-engineered for angled retaining wall layouts — common in Sydney's sloped suburban blocks, irregular boundary lines, and terraced garden designs. With over 40 years of trade experience, Retaining Walls Direct supplies the hardware that builders and landscapers across NSW rely on to get the job done right the first time.

When Do You Need a 45 Degree Corner Post?

Use a 45-degree corner post when your wall layout turns at an angle rather than a right angle. This is common in:

• Irregular block boundaries in Sydney's inner west, northern beaches, and Hills District
• Terraced garden beds that follow natural contours
• Driveway retaining walls that angle away from the property boundary
• Pool surrounds and entertainment area retaining structures

For right-angle turns, see our Corner, L-Post, Joiner & End Posts collection instead.

NSW Council & Engineering Requirements

In NSW, retaining walls over 600mm typically require council approval, and walls over 1.0m generally require a structural engineer's certification. Always check with your local council before commencing work. Useful references:

• NSW Planning — Complying Development Housing Code
• AS 4678-2002 — Earth Retaining Structures (Standards Australia)
