Alumasc
Alumasc Skyline - Sloping Coping 135 Degree External Angle
The Alumasc Skyline Aluminium Coping Angles (90° and 135°) provide a seamless, weatherproof solution for changes in direction along parapet walls. Manufactured from strong, recyclable aluminium and finished with a durable polyester powder coating, these coping angles ensure a clean, contemporary finish while protecting against the elements.
Supplied with one full fixing strap and one half strap, installation requires straps at maximum 1500mm centres, or as advised by coping size and wind uplift calculations. Copings SL12–SL36 are manufactured from 2mm aluminium, while SL42–SL60 are produced in 3mm aluminium for added strength.
Available in a mill finish or the standard palette of 26 RAL colours, with additional BS or RAL shades available to special order (subject to quantity and cost).
Please note: Copings installed in excess of 10m above ground level, or on exposed sites, may require visible fixings due to increased wind loads. Product images are for illustration purposes only and may not represent exact profiles or dimensions.
Larger sizes and bespoke copings are available on request.
