The Zen W40 Solid Steel Profile Window system is our most robust steel window profile, developed for projects that require exceptional strength, architectural presence, and dependable exterior performance. Suitable for fixed, casement, awning, and bifold window configurations, W40 is ideal for substantial openings where durability and refined detailing must work together.
Manufactured from solid steel, W40 is the strongest profile overall within the Zen range while still maintaining narrow, disciplined sightlines. This allows it to frame larger glazed openings with confidence, making it particularly well suited to external window applications in luxury residential and commercial architecture.
The strength and depth of the W40 profile create a more substantial architectural expression than lighter steel window systems, while preserving the clean lines and elegant proportions that define quality steel glazing. It is particularly effective in façades where windows are required to provide both performance and a strong visual anchor within the overall design composition.
The W40 casement and awning systems have been independently tested and certified to Australian Standard AS2047-2014 through Intertek SAI Global, giving architects, builders, and homeowners added confidence in its compliance, weather performance, and suitability for demanding Australian environments.
Whether used as a standalone feature window or integrated across a full steel door and window package, W40 offers a highly capable and enduring solution. For those seeking solid steel windows with strength, longevity, and refined narrow sightlines, W40 is a premium choice for exterior architectural applications.
