Correctly specified and installed posts determine whether a wall performs for 30+ years or fails within a decade — and on the Gold Coast's reactive clay western suburbs and steep hinterland terrain, post selection is critical. Retaining Walls Direct supplies the full range of hot-dip galvanised steel posts for Gold Coast retaining walls, from standard C-Channel (PFC) posts for residential garden walls to heavy duty H-Beam (UC) posts for engineer-specified designs on reactive clay sites.\u003c\/p\u003e\u003cp\u003eAll posts are manufactured to \u003ca href=\"https:\/\/www.standards.org.au\/standards-catalogue\/sa-snz\/building\/bd-001\/as--4678--2002\" target=\"_blank\" rel=\"noopener\"\u003eAS 4678-2002 Earth Retaining Structures\u003c\/a\u003e requirements and hot-dip galvanised to AS\/NZS 4680 for maximum corrosion resistance in Queensland's humid coastal climate.
