The Zen W40 Solid Steel Profile Door system is our most robust steel door profile, designed for projects that require maximum strength, architectural presence, and long-term exterior performance. Available in hinge, bifold, cavity sliding, barn sliding, and lift & slide stacking door configurations, W40 is suited to substantial openings where durability and visual refinement must work together.
Manufactured from solid steel, W40 offers the strongest profile overall within the Zen range while still maintaining narrow, disciplined sightlines. This combination allows the system to frame larger glazed openings with confidence, making it particularly well suited to exterior door applications across luxury residential and commercial projects.
The depth and strength of the W40 profile create a more substantial architectural expression than lighter steel systems, while still preserving the clean geometry and elegance that define steel doors. It is ideal for projects where doors are required to perform as both a functional building element and a strong part of the architectural composition.
The W40 hinge door system is also independently tested and certified to Australian Standard AS2047-2014 through Intertek SAI Global, providing confidence in its suitability for Australian conditions and reinforcing its performance across structural, weather, and compliance requirements.
Whether used as a primary external hinge doors, a large-format sliding opening, or integrated across a broader steel door and window package, W40 delivers a highly capable solution. For architects, builders, and homeowners seeking solid steel exterior doors with strength, longevity, and refined narrow sightlines, W40 is a premium and enduring choice.
