Learn more about our aluminium products


We provide a broad range of aluminium windows and doors.

Ideal for projects where planning or design requires the installation of sympathetic materials, our 58BW ST Steel Replacement Window System provides the look of steel with the benefits of aluminium. Designed to replace and complement existing steel windows, the range has been specifically developed for use on listed buildings, warehouses and similar buildings, where steel windows have always traditionally been fitted. Available in a wide range of styles including Top Hung, Side Hung, Fixed Light and French Casement, the system cleverly replicates the narrow sight lines associated with steel windows whilst providing superior performance and security. The system also includes hardware that is sympathetic to traditional steel window designs.


Aluminium provides strength and a high quality build finish.

Offering a wide range of standard and RAL colours. Anodised finishes are also available, with marine grade guarantees on request.
