External Sliding & Stacking Doors

Our Australian Made Steel Frame External Sliding & Stacking Doors are engineered for large-span openings that demand structural performance, refined detailing, and seamless indoor–outdoor integration. Designed and fabricated locally from precision-engineered steel, this premium system delivers expansive glazing, clean sightlines, and uncompromised durability in exposed environments.

Integrated into the Alspec ProGlide high-performance head and sill system, these doors are purpose-built for architectural projects requiring reliable weather protection, smooth operation, and long-term structural integrity. The result is a steel-framed sliding system that performs to commercial standards while maintaining the bold minimal aesthetic of the Urban X Premium range.

Ideal for alfresco transitions, courtyard openings, luxury residential builds, and commercial facades, this system allows generous openings without sacrificing strength or refinement.

Engineered for Scale & Performance

Built around the Alspec ProGlide performance platform, this system is designed for larger, heavier steel panels while maintaining smooth and controlled operation. The heavy-duty bottom roller system supports door panels up to 300kg, allowing for expansive glazing and increased panel sizes without compromising functionality.

Integrated sill drainage and sealing systems provide dependable weather management, making this door suitable for exposed applications where performance is as critical as aesthetics.

The result is a sliding system that feels substantial, moves effortlessly, and performs reliably over time.
