Architectural Coping

Ali-Fabs Architectural Coping is the only BBA-approved parapet coping in the UK

The Architectural Parapet Coping System is the only BBA-approved aluminium parapet coping system in the UK. Our systems comprises of concealed brackets incorporating an EPDM rubber seal and slide-lock fixing method that securely fixes the coping to the bracket.

Ali-Fabs Architectural Coping with hidden fixings is suitable for both high and low-rise buildings, that’s why it’s the ideal solution for new and refurbished parapet walls, columns and piers. All parapet copings are made to suit individual project requirements and are available for quick delivery. A complete system with fully fabricated fittings is available.

In addition, a cost-efficient alternative to coping stones, aluminium Architectural Coping offers a versatile and adaptable system that provides a complementary interface with aluminium flashings, soffits, fascias and cladding systems.
