Sloping coping is a wall capping system with an angled top surface, designed to direct rainwater away from walls and building façades. The sloped design provides a natural drainage path, preventing water from lingering on the wall surface and significantly reducing the chance of staining or freeze-thaw damage.
Made from high-grade aluminium, our sloping coping systems combine strength and lightness with outstanding corrosion resistance, making them ideal for both commercial and residential applications.
At Gutter Centre, we supply aluminium sloping coping systems that combine aesthetic appeal with advanced weatherproofing performance. Designed to suit a wide range of wall types and building styles, our sloping coping systems are an effective solution that ensures reliable coverage for parapet walls with a weathered or angled profile.
Our Skyline sloping aluminium coping system is manufactured to your exact wall thickness and profile, offering a secure fit and a neat, contemporary finish. Using a strap-fix method, the coping is installed without penetrating the surface, preserving its waterproofing integrity and allowing air to ventilate over the top of the wall. For projects requiring additional precision, we also offer a version fitted with top hat brackets, which means you no longer have to pack on site with marine ply to create the weathered profile.
Available in a galvanised mill finish or 26 PPC colour options, this aluminium sloping coping system is ideal for both new builds and refurbishment projects. Please allow 15–25 working days for delivery, as all units are manufactured to order following customer approval of the production drawings.

How do you select the correct size Skyline aluminium Sloping coping for my wall?
To select the coping size you must first measure the wall thickness you are covering (this needs to be finished wall thickness inclusive of any render or cladding) . Then select the coping wall thickness range, which is suitable, this will determine the width on the coping required and size of overhang. If you select the size of coping first, without measuring the wall thickness, the fixing straps may not fit.
Can I order bespoke sizes / non standard angles to fit my specific project?
Yes you can, speak to our team regarding the details of this so it can be correctly quoted. Once ordered you will have to approve production drawings on these before the order goes into manufacture. Bespoke items are strictly non returnable so you need to double check every dimension on the drawings before approving.
Curved parapet walls
If your building has a curved parapet wall, a timber template of the curve will need to be issued in order for us to manufacture. Radius items will be supplied in 1m length only.
How do I install Skyline aluminum Sloping coping?
Ensure minimum 18mm marine ply or non combustible alternative, and weatherproof membrane is fitted to the structure before commencing with the installation. Position bracket with EPDM seal centrally over the wall, at maximum 1.5m centres, or as recommended based on wind uplift calculations or coping size, maintaining a minimum 10mm gap from the bracket inside return edge to the external wall surface finish. It is always recommended to start from the corners and build out. All coping lengths must be butt jointed with a 3-4mm gap, for expansion at either end, making sure a fixing strap is located at each joint.
Can I install Aluminium sloping coping tight to the outside wall?
We recommend that you leave a minimum of a 31mm shadow gap between the finished external wall and the coping, otherwise you will run the risk of rainwater tracking back down the face of the building causing staining to the wall face.
