Walls over 2.0m, major surcharge loads from roads or structures, commercial and civil retaining applications, and sites with severely expansive soils all call for the 200 Series. With a 200mm flange width and the highest section modulus in our standard range, these posts are specified by structural engineers for Queensland's most demanding retaining wall projects. Retaining Walls Direct has supplied heavy duty posts to QLD engineers, builders, and civil contractors for over 40 years.\u003c\/p\u003e\u003ch3\u003eFeatures \u0026amp; Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHot-dip galvanised to \u003ca href=\"https:\/\/www.standards.org.au\/standards-catalogue\/sa-snz\/building\/bd-001\/as--nzs-4680\" target=\"_blank\" rel=\"noopener\"\u003eAS\/NZS 4680\u003c\/a\u003e — maximum corrosion resistance in Queensland's subtropical conditions\u003c\/li\u003e\n\u003cli\u003e200mm flange width — the highest standard section modulus in our post range\u003c\/li\u003e\n\u003cli\u003eAvailable in C-Channel and H-Beam (UC) profiles\u003c\/li\u003e\n\u003cli\u003eEngineered to accept 75mm and 100mm concrete sleepers\u003c\/li\u003e\n\u003cli\u003eSuitable for walls from 2.0m to 3.0m+ (engineer certification mandatory)\u003c\/li\u003e\n\u003cli\u003eSpecified for commercial, civil, and high-surcharge retaining wall applications across Queensland\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhen to Specify the 200 Series\u003c\/h3\u003e\u003cp\u003eThe 200 Heavy Duty Series is required when:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYour wall exceeds 2.0m in height\u003c\/li\u003e\n\u003cli\u003eThe project involves major surcharge loading — road traffic, heavy vehicles, or large structures above the wall\u003c\/li\u003e\n\u003cli\u003eThe application is commercial, industrial, or civil infrastructure\u003c\/li\u003e\n\u003cli\u003eYour structural engineer has specified 200 Series posts in their engineered design\u003c\/li\u003e\n\u003cli\u003eThe site has severely expansive soils or poor drainage with high hydrostatic pressure behind the wall\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor walls under 2.0m, see our \u003ca href=\"\/collections\/150-heavy-duty-series-brisbane\"\u003e150 Heavy Duty Series Brisbane\u003c\/a\u003e or \u003ca href=\"\/collections\/100-standard-series-steel-posts-brisbane\"\u003e100 Standard Series Brisbane\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eEngineering \u0026amp; Compliance\u003c\/h3\u003e\u003cp\u003eAll walls over 1.0m in Queensland require a building development approval and structural engineer's certification. 200 Series walls will always require a full engineered design.
