Crittall French doors bring the same slim steel sightlines and generous glazed panes as Crittall’s original window systems, in a traditional hinged, double-door configuration. Ideal for opening a room onto a garden or terrace, they combine the classic proportions of a period French door with the strength and slender frames only steel can offer. As an approved Crittall Specialist Partner since 1956, Metwin supplies and installs genuine Crittall French doors, not a steel-look imitation, for both residential and commercial projects across the UK, including listed buildings and conservation areas where authenticity matters.
Our French 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.
