Big steel for Sydney projects
Sydney builders and civil contractors use these sections for engineered walls over 2 metres, boundary retention on sloping blocks and commercial projects. Because every post is cut from larger lengths, quoting is case by case and includes freight to your site. Delivery is direct to site on a forklift truck as standard, with crane truck unloading available on request for tight access.
How to get a quote
Email your engineering takeoff, post schedule or drawings to info@retainingwallsupplies.com.au, or call 0485 856 986. Include section sizes, cut lengths and delivery postcode. Standard quotes go out the same day.
Frequently asked questions
Can I pick up big steel in Sydney?
Our sleeper range is available for pickup at Wetherill Park, but super heavy duty steel is cut and galvanised in Melbourne and delivered direct to your site or yard. The quote includes freight to your postcode.
Why are there no prices on the larger sizes?
Sections above 200 UC are cut from full-length stock, so the price depends on your cut list: the number of posts, lengths and offcut efficiency. Quoting case by case keeps the price sharp; most quotes are returned the same day.
Are the posts galvanised?
Yes. Every post is hot-dip galvanised after cutting. Watch for cheaper quotes on raw (non-galvanised) steel: buried steel without galvanising will not last in retaining wall service.
