Edcon Steel supplies a complete range of retaining wall post profiles, including H-posts (for intermediate joins), C-posts (for wall ends), and angled corner posts (for 90° or 45° turns). All posts are heavy-duty structural steel and typically hot-dip galvanised for superior corrosion resistance in Australian conditions.
Steel retaining wall posts are the backbone of any durable retaining wall, providing the strength and stability needed to hold back soil. Unlike timber, steel posts won’t rot or warp, making them a long-term solution for garden beds, landscaping tiers, or large structural retaining walls. We can custom-cut each post to your required length, ensuring you get the right fit for your wall height. Whether you’re a tradie on a civil job or a DIY homeowner building a garden wall, our friendly team is here to help with expert advice and quality steel, delivered Australia-wide.
Order online for nationwide delivery, or visit one of our stores in NSW (Brookvale, Revesby, Blacktown, Bathurst, and Orange) for expert advice and local pick-up.

Work Smarter with Edcon Steel
Plan your posts: Measure your wall height and add extra length for in-ground footing. Our team can help you choose and cut the right size.
Let us cut it: Save time with our precision cut-to-size service. No on-site sawing or heavy lifting required.
Protect the finish: All posts are hot-dip galvanised for outdoor use. If cutting on site, re-coat exposed ends to guard against rust.
Store smart: Keep posts off the ground and covered if stored outside. This prevents moisture build-up and keeps finishes intact.
Stock availability: Edcon Steel stocks a range of steel retaining wall products at all our NSW branches for quick pickup. If you require a different size, we can source it from our suppliers. Just let us know your specific requirements.
Common Uses and Sectors: Steel Retaining Wall
Steel retaining wall posts are used in a wide range of applications, from backyard projects to large-scale civil works. In residential landscaping, galvanised H-posts and C-posts are popular for building sturdy garden beds, terraces, and boundary retaining walls (often with timber or concrete sleepers). Builders and contractors use our posts in housing developments and renovations to retain soil for driveways, pools, and split-level foundations.
In civil and commercial projects, structural steel retaining wall systems are trusted for road embankments, car park retaining walls, industrial facilities and anywhere that requires reliable earth retention.
Edcon Steel supplies customers across New South Wales and Australia with steel retaining wall products for all these applications. From city projects in Sydney to rural builds in Bathurst and Orange, our steel retaining wall products are trusted to perform.
