Full Product Overview
The Trimax Gardentop Staircase – Dark Brown is a premium modular outdoor staircase system engineered for safe, durable and low-maintenance exterior access.
Designed for permanent installation in gardens, terraces, raised patios, decking areas and balcony access points, this staircase combines galvanised steel structural strength with high-performance TRIMAX® composite treads to deliver long-term outdoor durability without the maintenance requirements associated with traditional timber staircases.
Its dark brown TRIMAX® treads provide the natural appearance of wood while offering superior resistance to moisture, rot, warping and cracking — making the staircase particularly well suited to year-round exposure in changing weather conditions.
The anti-slip tread surface improves grip underfoot during wet conditions, helping enhance everyday safety for outdoor use. Meanwhile, the galvanised and powder-coated steel frame provides excellent corrosion resistance and dependable long-term structural integrity.
Available in multiple tread configurations ranging from 2 to 12 treads, the modular design allows the staircase to suit a wide range of finished floor-to-floor heights while maintaining a clean, contemporary architectural appearance.
Built to recognised EN structural standards, the Trimax Gardentop Staircase offers a significantly more robust and permanent solution compared with lightweight decorative outdoor steps or untreated timber stair systems.
