The Art of the Arch in Aluminium
Arched doorways and windows are among the most expressive elements in architectural design — from the sweeping Romanesque arches of medieval churches to the elegant fanlights of Georgian townhouses and the dramatic Art Deco curves of 1930s commercial buildings. Our steel-look arched doors bring this timeless architectural language into the 21st century, using precision-curved aluminium profiles with authentic astragal glazing bar detailing to create doors, screens and windows that honour the original while delivering contemporary performance.
Each arched door is individually manufactured to your exact dimensions and curve profile. The aluminium frames are curved using specialist bending equipment that maintains the slim, uniform sight-lines of our steel-look range — no distortion, no kinking, no compromise on the clean lines that define the Crittall aesthetic. Astragal bars are applied to both faces of the glass, creating the appearance of individually glazed panes in the traditional manner, while the glass behind is a single sealed double-glazed unit delivering modern thermal performance.
The result is a door or screen that looks like it could have been forged in a 1920s ironworks but performs like a precision-engineered 21st-century product — thermally broken, weathertight, secure and maintenance-free.

Arched steel-look doors are particularly sought after in Surrey's historic market towns and London's conservation areas — from Georgian properties in Richmond and Kew to Arts and Crafts houses in Guildford and Victorian villas in Wimbledon. They are equally at home in contemporary barn conversions, industrial loft spaces and modern homes where the architect wants to introduce a bold, sculptural element.
Heritage and Conservation Applications
For properties in conservation areas or those that are individually listed, arched steel-look doors offer a solution that satisfies both the homeowner's desire for modern performance and the conservation officer's requirements for sympathetic design. The slim aluminium profiles replicate the sight-lines of original steel windows and doors, while the dark finish options — matt black, anthracite grey and bronze — match the patina of aged metalwork.
We can replicate existing arched door and window profiles where the originals have deteriorated beyond repair, matching the curve radius, astragal pattern and proportions of the original metalwork. For new openings in heritage buildings, we work with your architect to design arched doors that complement the existing architectural language without resorting to pastiche — a distinction that conservation officers appreciate.
Our arched steel-look doors can be configured as single or double doors, with or without sidelights and fanlights, and with fixed or opening fanlights above. Hinged, pivoting and sliding configurations are available depending on the opening size and the client's requirements.
For non-steel-look arched doors in Alitherm 400, see our arched aluminium doors page. We also manufacture matching arched windows using the same in-house bending capability.
