The Zen FPS50 Slimline Tube Steel Door system is designed for projects that demand clean sightlines, structural strength, and flexibility across a wide range of configurations. Available in hinge, pivot, bifold, cavity sliding, barn sliding, and lift & slide stacking door systems, FPS50 is our most cost effective and versatile architectural steel door profiles.
Manufactured from cold formed tube steel, the FPS50 profile delivers a refined, slimline appearance while maintaining the strength required for larger glazed openings. Its balanced proportions make it well suited to both residential and commercial projects, whether used as a statement entry, rear door system, or integrated throughout an entire home.
A key advantage of the FPS50 system is its polyurethane injected profile construction, which enhances thermal efficiency and improves overall performance. This gives FPS50 excellent insulating properties compared to traditional non-thermally enhanced steel systems, making it a strong choice for projects where comfort and energy performance are important.
The result is a steel door system that combines architectural elegance, robust durability, and practical performance. For homeowners, architects, and builders seeking slimline steel doors with strong thermal properties and multiple design applications, FPS50 offers a refined and highly capable solution.
