From material choice to installation detailing, the Fluid Steel Door is designed with timelessness in mind.

Design

Its minimal aesthetic lends itself to clean, modern interiors as well as character-sensitive renovations.

Integrated Elegance
Available in bright steel or steel zinc magnesium, it offers surface finishes including powder coating or galvanising. Options for frameless installation and flush integration allow the design to sit quietly within any interior setting.

Tailored to Space
Whether specified as a pivoting centrepiece or subtle side-hung partition, the Fluid Steel Door adapts in size, form, and finish—ensuring each project benefits from both visual continuity and functional sophistication.

Behind the refined appearance is a performance-led system engineered for longevity and internal functionality.

Technology

The Fluid Steel Door is fully fabricated from recyclable steel, meeting strict European performance standards. It offers sound insulation up to 35 dB, barrier-free access, and is tested to 200,000 open/close cycles.

Fire-Rated Models
Where additional performance is required, Fluid Steel is available in four certified internal fire-rated variants: E30, EW30, E60, and EW60, compliant with EN 16034. Each model is tested for safety, durability, and acoustic insulation, with discreet design integration.

Performance Meets Practicality
With steel or aluminium glazing beads, wet or dry glazing options, and capacity for glass up to 42mm thick, the system delivers robust functionality in a slim, versatile frame.

A modern expression of restraint and strength, the Fluid Steel Door elevates the interior fabric of a building.

Architecture

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.

A Light-Filled Division
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.
