Spiral glass or metal outdoor staircases

A distinctive element of each Marretti collection is the spiral staircase with non-slip glass steps, suitable for outdoor spaces. The thickness of the step is variable (42-52 mm) in relation to the diameter of the staircase.

The metal parts are completely in stainless steel without welding and assembled by mechanical hooks only. They can have a glossy or satin finish.
