The 100 PFC Parallel Flange Channel is the standard residential C-Channel post for concrete sleeper retaining walls under 1.0m in stable, well-drained ground conditions. The most widely used retaining wall post in Australia for low garden walls, boundary walls, and landscaping retaining walls where lateral earth pressure is low and drainage is good.
With 40+ years of hands-on retaining wall experience across Australia, we specify the 100 PFC for walls under 1.0m on sandy coastal soils, well-drained loam, and stable ground conditions. All posts are hot-dip galvanised to AS/NZS 4680 and comply with AS 4678-2002 Earth Retaining Structures. Delivered direct to your site, Australia-wide.
If your site is on reactive clay or your wall exceeds 1.0m, upgrade to our 150 UC 30 H-Beam post. See our full guide: H-Beam vs C-Channel Steel Posts — Which Do You Need?
Walls over 1.0m require approval in most Australian states. All walls must comply with AS 4678-2002. See our Retaining Wall Regulations — State-by-State Guide.
