Why Choose This Aluminium Coping

This 3 m aluminium coping with a 125 mm external leg provides extended wall coverage and a sleek, architectural profile. The longer length ensures smoother wall runs with fewer visible joins, while the sloping design promotes efficient drainage. Built from 2 mm powder-coated aluminium, it’s lightweight to handle yet strong enough to withstand the toughest British weather. A perfect balance of form and function for projects where both aesthetics and durability matter.

Why choose the 125 mm external leg?
It provides extra wall coverage, improving weather protection and giving a proportionally balanced look on wider parapets.

Does the 3 m length reduce installation time?
Yes, longer sections mean fewer joins and a faster, cleaner installation process.

How does the slope improve performance?
It channels rainwater away from the wall surface, preventing staining and damp patches over time.

Is it available in custom colours?
Absolutely. We powder-coat every section to any RAL colour to match your project design.

What’s the best way to install this coping?
Use OMS’s concealed bracket system and sealant for a smooth, watertight joint with no visible fixings.
