The Zen W20 Solid Steel Profile Door system is defined by precision, restraint, and exceptionally fine steel sightlines. Available in hinge, cavity sliding, and barn sliding door configurations, W20 is our narrowest steel door profile overall, making it an ideal choice for interior applications where lightness and minimal visual interruption are essential.
Manufactured from solid steel, the W20 profile delivers a crisp, elegant appearance that suits refined residential interiors, boutique commercial spaces, and architectural projects where detail matters. Its slim proportions allow glazing to take centre stage, creating internal steel doors that feel open, tailored, and highly resolved within the surrounding architecture.
W20 is particularly effective as an internal steel door system, whether used for home offices, studies, wine rooms, living zones, or transitional spaces that benefit from separation without losing connection. The profile’s narrow face dimensions create a sophisticated architectural language that works comfortably in both contemporary and more classic interiors.
While visually delicate, W20 retains the permanence and integrity of solid steel construction. The result is a profile that offers understated strength with a distinctly premium finish. For projects seeking slim internal steel doors with refined detailing and timeless character, W20 remains one of the most elegant solutions in the Zen range.
