Add lagging, add a bearer, add a second pipe stacked alongside the first, and 200mm stops being enough. This is the taller version of the same crossover, built on deep pultruded I-beam legs instead of short channel, giving 210mm to 300mm underneath.\u003c\/p\u003e\n\n\u003cp\u003eThe extra height is the whole point, so the leg section changes with it. An I-beam carries the deck load across a longer unsupported drop without flexing the way a taller channel leg would, which is why the taller platforms are a different build rather than the same unit on longer legs.\u003c\/p\u003e\n\n\u003ch3\u003eWhere it earns its place\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCrossing insulated heating and chilled-water pipe runs where lagging adds 50mm or more to the pipe diameter\u003c\/li\u003e\n\u003cli\u003eStepping over stacked or twinned service runs sharing one route across the roof\u003c\/li\u003e\n\u003cli\u003eBridging deeper cable baskets and combined pipe-and-tray runs\u003c\/li\u003e\n\u003cli\u003eCrossing low bund walls, kerbs and upstands too tall for a standard platform\u003c\/li\u003e\n\u003cli\u003ePlant rooms and service yards with raised pipe supports beneath the run\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eGlass-reinforced polyester (GRP) open-mesh grating on pultruded GRP I-beam legs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClearance under\u003c\/th\u003e\n\u003ctd\u003e210mm, 240mm, 270mm or 300mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall height\u003c\/th\u003e\n\u003ctd\u003eApproximately 248mm to 338mm depending on clearance selected\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDeck sizes\u003c\/th\u003e\n\u003ctd\u003e465 x 615mm, 615 x 996mm, 996 x 996mm, 996 x 1220mm (span x width)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDeck finish\u003c\/th\u003e\n\u003ctd\u003eGritted anti-slip surface, integral to the moulding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEdge marking\u003c\/th\u003e\n\u003ctd\u003eContrasting high-visibility nosing to both step edges\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eFree-standing, no fixing into the roof deck required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCorrosion\u003c\/th\u003e\n\u003ctd\u003eNon-corroding, non-conductive, no painting or galvanising\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied\u003c\/th\u003e\n\u003ctd\u003eAssembled, plain and unbranded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eChoosing a size\u003c\/h3\u003e\n\u003cp\u003eClearance is measured from the roof surface to the underside of the deck, so measure the tallest point of the obstruction as installed, including lagging and any bearer or support it sits on, then take the next clearance up. Span is the direction you walk across; width is the platform you stand on. A single pipe usually wants a short span and a generous width rather than a large square deck.\u003c\/p\u003e\n\n\u003cp\u003eIntermediate clearances at 220, 230, 250, 260, 280 and 290mm are made in the same range and are available to order.

This one starts where that stops, on I-beam legs. If the obstruction is under 200mm, the standard version is the cheaper choice.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy does the price not change with clearance?\u003c\/strong\u003e\u003cbr\u003eBecause the maker prices by deck size, not by leg length. A 996 x 996mm platform costs the same at 210mm as at 300mm, so choose the clearance that actually fits rather than the shortest one.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it need fixing down to the roof?\u003c\/strong\u003e\u003cbr\u003eNo. It is free-standing and sits on the roof surface, which is what suits single-ply and rubber membranes where penetrations are best avoided. On an exposed roof, position it against an upstand or plant base where wind uplift is a concern, and remember a taller platform catches more wind than a low one.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill the legs mark the membrane?\u003c\/strong\u003e\u003cbr\u003eThey bear on the covering, and a taller platform concentrates the same weight through the same four feet.
