{"product_id":"grp-step-over-access-platform-roof-pipe-crossover","title":"GRP Step-Over Access Platform – Anti-Slip Fibreglass Crossover for Roof Pipe Runs, 17 Sizes","description":"\u003cp\u003eEvery flat roof that carries services eventually forces the same bad choice on whoever maintains it: step over the pipe run and hope, or tread on it. Neither is acceptable once a roof is visited regularly, and lagged pipework crushes under bootfall long before anyone admits the route has become a hazard. A free-standing step-over platform removes the decision entirely by lifting the walking route clear of the obstruction.\u003c\/p\u003e\n\n\u003cp\u003eThis one is moulded from glass-reinforced polyester rather than steel or aluminium, which matters more on a roof than it does at ground level. GRP does not corrode, does not need painting, and carries no galvanic risk where it sits against aluminium flashings, zinc details or a single-ply membrane. It is also light enough for one person to reposition when the roof layout changes.\u003c\/p\u003e\n\n\u003ch3\u003eWhere it earns its place\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCrossing insulated pipe runs, condensate lines and cable trays on flat roofs\u003c\/li\u003e\n\u003cli\u003eMaintenance routes to air handling units, chillers and plant platforms\u003c\/li\u003e\n\u003cli\u003eBridging low upstands, kerbs and threshold changes between roof levels\u003c\/li\u003e\n\u003cli\u003eSolar array service routes where cabling and mounting rails cross the walkway\u003c\/li\u003e\n\u003cli\u003eGround-level plant rooms, pump houses and service yards\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\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 yellow high-visibility nosing to both step edges\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFootprints\u003c\/th\u003e\n\u003ctd\u003e465 x 615mm, 615 x 615mm, 465 x 996mm, 465 x 1220mm, 615 x 996mm, 996 x 615mm, 578 x 1220mm, 996 x 996mm, 1220 x 1220mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClearance under\u003c\/th\u003e\n\u003ctd\u003e100mm, 150mm or 200mm.

Clearance is measured from the roof surface to the underside of the deck, so a 150mm lagged pipe sitting on a 25mm bearer needs the 200mm option, not the 150mm. Span is the direction you cross in and width is the platform you stand on, so a single narrow pipe usually wants a short span and a generous width rather than a large square. Where a route crosses several services, two platforms placed end to end usually work better than one oversized unit.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked\u003c\/h3\u003e\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 makes it suitable for single-ply and rubber membranes where penetrations are best avoided. On exposed roofs, position it against an upstand or plant base where wind uplift is a concern.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill it damage an EPDM or single-ply membrane?\u003c\/strong\u003e\u003cbr\u003eThe legs bear on the membrane, so on a soft or newly laid roof we recommend setting it on protection pads or a matting run.

GRP is unaffected by rain, frost and UV, and unlike steel it will not rust where the coating is chipped during handling.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it slippery when wet or icy?\u003c\/strong\u003e\u003cbr\u003eThe deck is a gritted open mesh, so surface water drains straight through rather than sitting on the tread. It behaves well wet.
