Aluminium Casement Doors

Alteza aluminium casement doors’ durability, high-performance levels and low maintenance make these an ideal addition to commercial and/or larger residential projects. Our casement doors can either have fixed panels or be attached to the frame with one or more hinges, typically allowing them to open to the side. They are held open by ‘casement stays’, small metal bars that open and close in a scissor motion. As a leading Aluminium Casement Doors Manufacturer, we offer customisation in glazing & glass options, robust hardware, mesh, choice of colours and sizes.
