Architecture
A modern expression of restraint and strength, the Fluid Steel Door elevates the interior fabric of a building. It’s designed to blend quietly into architecture while enhancing openness and spatial clarity. Its slender lines and refined proportions make it ideal for linking rooms, creating quiet zones, or marking subtle thresholds in open-plan spaces.

With face widths starting at just 23mm, the door introduces light while offering acoustic separation—ideal for homes, workspaces, and public interiors seeking a visual connection without compromise.
Adaptable Compositions
Available in single or double-leaf designs, with options for sidelight and fanlight integration, the system supports a range of spatial configurations without overpowering the architectural language.
Fire Resistance
Optional radiant heat control for 30 or 60 minutes, meeting EN 13501-2 standards. Ideal for safety-critical spaces, they deliver discreet protection without compromising on design.
