Retaining Wall Steel Posts — Sydney NSW

Retaining Walls Direct supplies hot-dip galvanised steel posts for concrete sleeper retaining walls across Greater Sydney — delivered direct to your site in Penrith, Castle Hill, Parramatta, Blacktown, Campbelltown, the Northern Beaches, Eastern Suburbs, Inner West, and everywhere in between. C-Channel and H-Beam posts available to suit every wall height and soil condition across NSW.

With many years of hands-on retaining wall experience across New South Wales, we specify the correct post for every Sydney site. Western Sydney's reactive Wianamatta Shale clay demands H-Beam posts for structural performance. Sydney's sandstone suburbs can often use C-Channel for low walls. We'll help you get it right.

H-Beam vs C-Channel — Sydney Specification Guide

C-Channel Posts — Sydney

C-Channel (PFC) posts are the standard post for walls under 1.0m in stable, well-drained ground — North Shore, Northern Beaches, Eastern Suburbs, and Sutherland Shire sandy soils.

H-Beam Posts — Sydney (Recommended for Western Sydney)

H-Beam (UC) posts are the structural post for reactive Wianamatta Shale clay sites in Western Sydney (Penrith, Blacktown, Campbelltown, Liverpool), walls over 1.0m, driveway walls with vehicle surcharge, and all engineer-specified designs.

NSW Building Approval Requirements

Walls over 1.0m require a DA or CDC. All walls must comply with AS 4678-2002 Earth Retaining Structures. See our Retaining Wall Regulations — State-by-State Guide.
