Originally designed as a replacement for period steel-type windows, the AluK Optio 58BW ST steel replacement aluminium casement window offers an ultra-slim 46mm sash, creating a minimal sightline.
Despite its origin as a heritage replacement, this minimalist offer can also be designed to create a contemporary aesthetic, while maximising the glazed area.

A more ornate design replicating period steel window installations
A simple design with an angled fall away from the glass line
A cleaner and contemporary design, creating a minimalist contemporary appearance
Our aluminium window and door ranges use a special flash-anodising process.
Completed ahead of powder coating this creates a protective anodised layer of aluminium oxide providing a better substrate for powder coating but also preventing filiform corrosion.
It means that our window and door range is supplied in a marine grade finish as standard and guaranteed for 10-years.
Our standard colour ranges include a choice of white, anthracite grey, chocolate brown and deep black, plus dual colour anthracite grey-on-white and deep black-on-white.
We can also offer you access to a range of textured finish options and supply any RAL colour on special order, giving your customers the flexibility to pick out the perfect shade to compliment their property.
