Crittall patio doors bring the same slim steel sightlines as Crittall’s window and door systems, in a sliding configuration designed to connect your home to the garden without taking up space on either side. Built on Crittall’s GS20 sliding system, they offer smooth operation and generous glazed panes, a practical alternative to hinged French doors where space is at a premium.
As an approved Crittall Specialist Partner since 1956, Metwin supplies and installs genuine Crittall patio doors, finished in Duralife polyester powder coating or hot-dip galvanised as standard, for residential and commercial projects across the UK.
Our patio doors are finished to order in hot-dip galvanised as standard, or a wide choice of bespoke RAL colours. Black remains the most popular choice for its classic Crittall look, but the full range is available to match your project.
