spiral resin
The stainless steel and resin spiral staircase is composed of resin-coated wooden steps that can be supplied in various finishes and colors also to sample.
The step thickness is variable (42-52 mm) in relation to the staircase diameter (Ø from 100 cm to 300 cm). The metal parts are completely made of seamless stainless steel, assembled only through mechanical couplings. They can have a polished or satin finish.
