Wind pressure on the underside of a coping overhang generates a peel force at the fixing points. A 5mm bracket resists that force more effectively than a 4mm bracket, which is why the heavier bracket is paired with the heavier gauge coping on commercial and exposed-site projects.

When a coping is bolted or screwed directly through its top surface to the wall below, every fixing hole is a potential water entry point. The washer and sealant at each fastener will eventually degrade, and the fastener itself is under repeated stress from thermal movement in the coping. With the 4mm bracket, the coping presses onto the bracket from above and is held mechanically without any penetration through the coping surface.

On a fully exposed parapet, the temperature differential between a hot summer day and a cold winter night in Essex or across the South East can be 40 degrees or more. A 3m length of aluminium flat coping will expand and contract by several millimetres across that range. A bracket-fixed system accommodates this movement by allowing the coping to slide fractionally over the bracket rather than being constrained at fixed points.

The 4mm aluminium bracket can be fixed to masonry, concrete, structural steel and timber substrates using the appropriate fixings for each. For masonry, use corrosion-resistant masonry anchors. For concrete, use concrete anchors. For steel or timber, use stainless steel or similarly corrosion-resistant fixings. The bracket itself is aluminium, which eliminates bi-metallic corrosion risk between bracket and coping. The fixings used to attach the bracket to the substrate must also be corrosion-resistant to avoid accelerated degradation at the fixing point.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003e\u003cspan\u003eWhy is the bracket thicker than the coping?\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe bracket is 4mm and the coping is 2mm because they have different structural roles.

The coping, on the other hand, is a weather shield profile that sits on the bracket: it does not need to carry structural load in the same way.

When a flat coping system is installed along a parapet wall, the straight lengths leave an open profile at each end of the run.

The closed stopend caps that end completely, creating a sealed termination that is weathertight on all sides.

A domestic rear extension in a sheltered suburban setting with a modest parapet wall width is a typical example. But the moment you move onto a commercial flat roof, a taller building, an exposed site on the Essex coast or the Thames Estuary, or a parapet wall that is wider and therefore puts more leverage on the corner piece, the specification changes. A 3mm gauge corner is not just marginally thicker than a 2mm. It is stiffer, it resists wind uplift more effectively, and it is the gauge that most commercial specifiers and NHBC-registered builders reach for on new-build projects where the coping is expected to perform for decades without remedial work.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis 3mm aluminium flat coping 90 degree corner is the right-angle component for the 3mm flat coping system with a 75mm external leg.

On a standard rectangular extension, dormer, or flat-roofed outbuilding, those corners are right angles, and if you are running aluminium flat coping along the top of the parapet, you need a proper corner piece at each turn. A mitre cut on two lengths of coping can be done, but the joint sits right at the most exposed point of the detail. Wind-driven rain does not need a large gap to get in under a parapet coping, and a poorly finished corner is one of the most reliable sources of water ingress into the flat roof edge build-up.

It integrates directly with the 2mm flat coping lengths running either side of it and is available powder coated in any RAL colour to match the rest of the system.

It is designed for parapet walls where two faces meet at a right angle, which is the standard junction on rectangular flat roof extensions, box dormers, flat-roofed garages and most commercial flat roof perimeters. The 75mm external leg sits over the outside face of the wall, providing the overhang and drip detail that keeps rainwater well clear of the wall below.

Instead of a fabricated mitre with a seam at the most exposed point of the parapet, the corner piece is a single pre-formed component that covers the change of direction cleanly.

A 90 degree angle is a right angle, which is what you get on a standard rectangular building.

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.

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.

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.
