Powder-coated aluminium doesn't. This flush-joint round system slots together without visible collars for a clean vertical line down the wall, and every piece you need for a real installation is here: 3m lengths, bends, swannecks around eaves overhangs, shoes, clips, hoppers and access plates.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFlush-joint round aluminium downpipe in 63mm and 76mm diameters\u003c\/li\u003e\n\u003cli\u003e12 components — pipe lengths, clips, jointers, bends, branches, swannecks, shoes, hoppers, access plates and outlet connectors\u003c\/li\u003e\n\u003cli\u003eTextured Black or Anthracite Grey (RAL 7016) powder-coated finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDiameters\u003c\/th\u003e\n\u003ctd\u003e63mm and 76mm round\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePipe length\u003c\/th\u003e\n\u003ctd\u003e3m per length\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eJoint type\u003c\/th\u003e\n\u003ctd\u003eFlush joint (internal jointer, no external collar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003ePowder-coated aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColours\u003c\/th\u003e\n\u003ctd\u003eTextured Black, Anthracite Grey (RAL 7016)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBend \/ branch angle\u003c\/th\u003e\n\u003ctd\u003e92.5°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHopper head size\u003c\/th\u003e\n\u003ctd\u003e300 x 250 x 200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhich diameter do I need?\u003c\/strong\u003e Match the downpipe to your gutter outlet. 63mm is the standard choice for most domestic roofs; 76mm suits larger roof areas, longer gutter runs and commercial buildings where flow rates are higher.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a swanneck for?\u003c\/strong\u003e Where the roof overhangs the wall, the pipe has to step back from the gutter outlet to the wall face. The adjustable swanneck makes that offset in one piece rather than cobbling together two bends.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many clips do I need?\u003c\/strong\u003e Fix a clip near the top of each 3m length and at roughly 1.8–2m intervals down the run, plus one just above the shoe. Use adjustable pipe clips where the wall face is uneven or you need to set the pipe off the wall.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is an access plate?\u003c\/strong\u003e A removable inspection plate fitted into the run so a blockage can be cleared without dismantling the pipe — worth fitting near the base of any run that collects leaves.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the flush joint need sealing?\u003c\/strong\u003e The internal jointer locates the pipe ends and keeps the outside line clean; downpipes run under gravity and are not pressurised, so joints are located rather than sealed.\u003c\/p\u003e\n\u003cp\u003eThis system connects straight onto our \u003ca
