A variety of widths and shapes of aluminium coping available. Wind tested to 144 mph, you will ensure ultimate performance and longevity, whatever the elements throw at you.

Aluminium Secret Fix copings
customised for your Project

Wall copings are an integral part of any building structure, providing a watertight protective barrier for parapet walls and roofs.

In basic terms, the coping itself is not bolted to the wall, but a bracket is, which the coping attaches to. This means the finished coping has a clean visual line, and also benefits from being watertight as it has no holes going straight through it.

The bracket is extruded in a specific design that makes the coping clip-fix to it. The brackets are bolted to the wall and then the coping is pressed securely on top. This attachment is so secure that it often means the coping can never be taken off again without damaging it.

HJA’s aluminium wall capping systems are available in three standard profiles & bespoke options:

  • Squared 
  • Weathered
  • Ridged

Advantages of Secret Fix Copings

  • Wind tested to 144mph
  • Custom-made
  • Easily cut and formed.
  • Lightweight: a big advantage both during construction and in reducing building mass.
  • Wide range of decorative finishes: it's often desirable to match copings with window frames. We can offer a wide range of colours to suit your applications.
  • Green credentials: aluminium is made from recycled material and when the coping or structure reach the end of their life the aluminium is also easily recycled again.
  • Polymer weather sealing gaskets to prevent wind rattle. 

 

Secret Fix Powder Coating & Finishing

Our aluminium secret fix copings come in a vast range of colours, available from standard RAL & BS Colours to Metallics, meaning you can create a unique aesthetic, no matter what the application may be.
