Finish & Function

Weather-Resistant Steel Doors in Any Size or Configuration

Bathrooms, kitchens, living areas, and utility rooms benefit from our ready-to-fit black steel doors, available for rapid dispatch across a wide choice of colours, finishes, and ironmongery. Solid steel construction handles rain, frost, UV exposure, and years of daily use without losing its finish or structural integrity. Glass options span multiple thicknesses, acoustic ratings, and transparency levels, while handle and lock selections let you fine-tune the look. Anything outside the standard catalogue is manufactured to your drawings. Get in touch to explore the range or set up a trade account.
