Why Choose This Aluminium Coping

This 3-metre sloping aluminium coping is perfect for longer parapet walls or commercial applications where fewer joints and a sleek visual line are preferred. The extended 125 mm leg ensures deeper wall coverage, offering added protection against heavy rainfall and wind-driven moisture. With its precision fit, clean edges, and powder-coated finish, it’s built to deliver a refined architectural look that lasts for years.

Why choose 3 m aluminium coping instead of shorter sections?
Longer 3 m lengths create fewer joints, resulting in a neater, more continuous look with faster installation.

What’s the benefit of a 125 mm external leg?
The extended leg offers additional wall coverage and greater protection against weather exposure.

Can this be used on commercial projects?
Yes, it’s widely used across commercial, industrial, and modern residential buildings due to its strength and professional finish.

Is this coping compatible with sloped wall systems?
Absolutely. It features a built-in slope that channels water away from the parapet to keep walls dry and clean.

Can I get a custom colour or size?
Yes, we can powder-coat in any RAL colour and manufacture bespoke sizes to meet your exact project requirements.
