If you have worked on any volume of residential or commercial flat roofing in the South East, you already know this. L-shaped extensions, bay projections, angled boundary walls, and awkward plot configurations mean that 90 degree corners are only half the story. When that wall turns at 135 degrees and you have no corner piece to match the coping run, you end up with an exposed joint that the weather will find in short order. Water tracking back under the coping at a badly finished corner is one of the most common causes of damp ingress into the flat roof build-up, and it is entirely avoidable.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis 2mm aluminium flat coping 135 degree corner is the purpose-made solution. It forms a neat, weathertight junction wherever your parapet wall changes direction at an obtuse angle, and it matches directly into the 2mm flat coping lengths running either side of it. Manufactured here in Chelmsford, Essex, and available powder coated in any RAL colour to match your project spec exactly, it removes the guesswork from corner detailing and keeps the whole system tight from day one.\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cspan\u003eProduct Overview\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis corner piece is part of the Online Metal Store Ltd 2mm aluminium flat coping range. It is designed for parapet walls where the wall direction changes at a 135 degree angle, which is the angle you get when two walls meet at an obtuse junction rather than a straight right angle. The 75mm external leg sits over the outside face of the wall, providing the overhang and drip detail that keeps water clear of the substrate below. The internal leg matches the profile of the standard flat coping lengths so that the transition from straight run to corner is flush, tight and consistent.

Even done carefully, a mitred joint has a seam running straight through the most vulnerable part of the detail.

That means there is no seam at the point where two wall faces meet, which is exactly where the wind-driven rain wants to find a gap.
