L’Elicoidale is an innovative patented system in Europe.
The patent envisages the absence of the classic column present in all spiral staircases and the use of a reinforced concrete monolithic step.
This system enables the design and construction of staircases that reach significantly greater heights – up to 15 metres – compared to heights normally reached with traditional helical staircases.
The central column, unique in its kind and patented as a result of its almond-shaped geometry and torsional style, eliminates the restricting centre column of ordinary spiral staircases, creating a much wider and walk-on passageway even in the smaller versions. It also enables greater opening of the tread as a result of the special side sections.
The staircases are patented and designed to comply fully with the safety and anti-seismic standards.
Production extends to open staircases and closed risers in a wide range of standard diameters.
The work is completed with the supply of all useful accessories, customising and integrating them with the furnishing of the entire area, such as claddings, finishes and railings.
On request, the company manufactures staircases with customised diameters.
