Spiral staircase outdoor TORONTO Anthracite

The DOLLE TORONTO spiral staircase in anthracite offers the perfect combination of durability, safety, and contemporary design — suitable for both indoor and outdoor use. Its stylish anthracite colour seamlessly blends with modern architecture while adding a bold statement to your space, whether it’s a garden terrace or an interior loft space.

Built to Last – Tested for Strength

All components, including the treads, are hot-dip galvanised and powder coated for superior protection against corrosion and wear. The staircase has also undergone TABER abrasion testing, ensuring long-lasting performance even in the most demanding environments.

Designed for Safety & Comfort

The perforated steel treads provide a non-slip surface, making them ideal for wet or icy conditions — comfort and security combined. For extra safety, especially for families with children, riser bars can be added to reduce the open space between the steps/treads.

Space-Saving and Fully Adjustable

The DOLLE TORONTO is an incredibly space-efficient staircase and can be installed in areas with limited room. It’s height-adjustable from 246 cm to 399 cm using the included spacers or by adding/removing treads. The staircase is available in two diameters: 125 cm with 3 balusters per tread and 155 cm with 4 balusters per treads. Also to optimize safety.

Elegant and Cohesive Aesthetic

By choosing the matching railing and landing banister systems in anthracite, you can create a visually cohesive and elegant space. This colour palette supports a contemporary and streamlined design, where each component enhances the overall architectural expression.

Matching Landing Banister in anthracite – Safety and Style

To complete the installation, we offer a matching landing banister system that continues the staircase's design seamlessly onto the landing. The banister stands at a secure 90 cm height with gaps no wider than 100 mm, ensuring safety in every aspect.

You’ll need a starter kit (1 metre) to connect the railing to the staircase, followed by as many 1-metre extension packs as your space requires. For example, 4-metre landing needs 1 starter pack + 3 extensions. If your landing is shorter (e.g., 3.8 m), the final section can be trimmed to fit.

Construction and Installation

A stable foundation is essential — we recommend a base of at least 40 x 40 x 120 cm (L x W x D) under normal soil conditions.

The staircase is suitable for left- or right-turn configurations and can be installed in square or round openings, which should be at least 10 cm wider than the staircase diameter selected.

All DOLLE spiral staircases comply with European building standards EN 1991 and EN 1993.
