In Melbourne, this typically means well-drained sandy loam or decomposed granite soils found on the Mornington Peninsula, parts of the outer east (Lilydale, Yarra Glen), and elevated sites in the Dandenong Ranges where drainage is excellent and reactive clay is absent. On Melbourne's more typical reactive clay soils, the H-Beam 150 Series is the correct specification at this wall height range.\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 — corrosion-resistant across Victoria's coastal, alpine, and inland conditions\u003c\/li\u003e\n\u003cli\u003e150mm flange width — greater bending resistance than 100 Series C-Channel for taller wall applications\u003c\/li\u003e\n\u003cli\u003eEngineered channel profile accepts 75mm, 100mm, and 120mm concrete sleepers\u003c\/li\u003e\n\u003cli\u003eSupplied in standard lengths — cut to required embedment depth on site\u003c\/li\u003e\n\u003cli\u003eLighter than 150 Series H-Beam — easier to handle on sites with difficult access\u003c\/li\u003e\n\u003cli\u003eSuitable for walls between 1.2m and 1.8m in stable, well-drained, non-reactive ground conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIs C-Channel 150 Right for Your Melbourne Site?\u003c\/h3\u003e\u003cp\u003eBefore specifying C-Channel 150 Series for a Melbourne project, consider the site geology carefully:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable sites\u003c\/strong\u003e — well-drained sandy loam or decomposed granite soils on the Mornington Peninsula, outer eastern suburbs (Lilydale, Healesville), and elevated Dandenong Ranges properties with good natural drainage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable\u003c\/strong\u003e — reactive clay soils across Melbourne's inner west (Footscray, Sunshine, Werribee), northern growth corridors (Craigieburn, Mickleham, Donnybrook), or any site where soil swelling during wet winters will generate significant lateral pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhen in doubt\u003c\/strong\u003e — specify H-Beam 150 Series.
