Benefits of Our Steel Windows

Manufactured to the highest standards and to your exact specifications, our slimline windows are both practical and aesthetically pleasing. All come with a certified B-thermal rating as standard. Steel windows have the slimmest of sightlines allowing maximum light into your home. A range of styles is available from cutting-edge to traditional. And, thanks to our engineering capabilities, our lead times are some of the shortest in the industry.

Classic Contemporary Steel Windows

The W20 series of steel window sections is the most popular and diverse steel framing system available. The system not only offers the thinnest possible sightlines but also offers significant strength allowing it to be used for multi-light and curtain wall assemblies.

Traditional Steel Windows

The SMW series of steel window sections are the oldest steel window sections currently available. Used extensively throughout the last century, the section is commonly associated as the classic steel window seen on 1000’s buildings nationwide. Unlike other manufacturers we still use the original un-modified sections to maintain the slim site-lines, enabling us to offer double glazed replica windows that can be used within existing apertures without any modification work

On a functional level we are the only company to achieve a certified B-thermal rating for slimline steel and our doors comply with all Part L regulations about conservation of fuel and power. This means you’ll stay warmer in winter whilst reducing energy use and bills.

As every project is different, and due to the bespoke nature of our products, it’s difficult to provide a quote without understanding the specifics of the project. However, you can request your quote here.

Our advances in engineering mean that our steel door frames are maintenance free, aside from the occasional window clean! Our frames have intricate and hidden welds to exacting technical drawings and once manufactured, the entire frame is dipped in its entirety, in to a molten zinc mix (a process known as galvanising). This process puts a thin yet robust layer of anti-rust coating over the frame, which is then painted to your chosen RAL colour.

For us, bespoke means bespoke! We provide plenty of options so that you can achieve the right feel for your project. Whether you are aiming for contemporary or something more classic, we are here to help.

All of our products are proudly designed and made here in the UK. You can find our showroom at: Unit 1, Hobbs New Barn, Climping, Littlehampton BN17 5RE (Map)

As our products are designed and manufactured right here in the UK, we boast some of the best lead times in the industry. Currently, our average lead time is around 12 weeks.
