Our customers are typically; Homeowners who are looking for one or two arched windows for their home, Window Installers requiring a bespoke curved frame for their project, or Fabricators of square aluminium frames, who are in need of an aluminium bending specialist to help with their arched and angled frames.

Arched Aluminium Windows

One of our standout offerings is the creation of bespoke arched aluminium windows.

These windows not only infuse a distinctive charm into a building’s aesthetics but also harness the durability and lightweight nature of aluminium. The bending process is meticulously managed by our skilled professionals, ensuring that each curve and circle is executed with utmost precision and attention to detail. Additionally, we specialise in crafting curved top lights for doors which complement the design integrity of any entrance. These curved top lights not only enhance the overall appearance of a door but also allow for an influx of natural light, creating an inviting and well-lit ambiance indoors.

We can create a curved frame in a choice of RAL colours. Slim aluminium shapes are our speciality.
