Outdoor metal staircase GARDENTOP Trimax® - Anthracite

Elevate your outdoor living space with the GARDENTOP outdoor staircase, designed for durability, style, and functionality. With a robust steel structure and composite treads, this staircase seamlessly connects your outdoor areas—from balconies to patios, decks to lawns. Featuring clean, pure lines and concealed fixings, the GARDENTOP staircase offers a sleek and modern look that complements any outdoor design. Choose your tread width (80cm or 100cm) and color (dark brown or anthracite grey) to perfectly match your aesthetic.

Engineered for the outdoors, the GARDENTOP staircase is crafted from weather-resistant, hot-dip galvanized steel, ensuring durability against the elements. Non-slip treads provide safety in all conditions, while the staircase is rigorously tested to handle up to 700 kg total load and 200 kg maximum point load, exceeding European safety standards EN1991 and EN1993.

Select the ideal height for your space, with configurations ranging from 2 treads (36–44 cm) to 12 treads (216–264 cm). You can also opt for no banister, a one-sided banister, or add a second banister for enhanced safety. The matching handrail kit, made from aluminium and hot-dip galvanized steel, ensures easy mounting and a polished look.
