45 Degree Corner Steel Post Canberra ACT

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

When your retaining wall needs to change direction at a 45-degree angle, a standard post won't do the job. Our 45-degree corner steel posts are purpose-engineered for angled retaining wall layouts — common across Canberra's irregular block shapes, sloped suburban terrain, and curved boundary lines throughout Belconnen, Tuggeranong, Gungahlin, and the inner north. Hot-dip galvanised and built to handle the ACT's frost conditions and reactive clay soils, these posts are ready to install straight from delivery. Retaining Walls Direct has supplied Canberra builders and landscapers for over 40 years.

• Hot-dip galvanised to AS/NZS 4680 — corrosion and frost resistant for ACT conditions
• Engineered to accept standard 75mm and 100mm concrete sleepers on both faces
• Available in 100 Series (standard residential) and 150 Heavy Duty Series
• Pre-drilled and ready to install — no site fabrication or welding required
• Compatible with our full C-Channel and H-Beam post system
• Suitable for walls up to 1.8m (engineer certification required above 1.0m in ACT)

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. Common applications across Canberra include:

• Irregular boundary lines on ACT blocks that don't follow a right-angle grid
• Terraced garden beds that follow natural contours on sloped Canberra blocks
• Driveway retaining walls that angle away from the property boundary
• Landscaping projects where curved or angled wall layouts are required

For right-angle turns, see our 90 Degree Corner Steel Posts Canberra. For straight-run terminations, see our End Posts & Joiners.

ACT Planning & Engineering Requirements
