Due to it's inherent strength, steel allows for our frames and real glazing bars to be super slim with out sacrificing strength or durability. This natural property of steel lends itself to almost unlimited design options. Especially important when you would like to maximise the natural light entering your property. The double doors in Figure 1 above are over 2.6 metres tall!


Super slim, elegant and STRONG

Our external black steel doors and windows are galvanised prior to being painted with a powder coated finish. Your doors don't have to be painted black this is just how we like them! The galvanising process protects the steel profile from rust corrosion. This ensures that your windows and doors will out live you or me.

Glazed using advanced double glazed units. Our black steel doors are capable of meeting current building regulations in terms of thermal performance. We like to use toughened glass on all our glazing to ensure that your doors are not only secure but also safe from knocks and bangs.

Combining glazing with modern Euro locks and you have a door and window set that will last you a life time and will look great for decades to come.
