The metal parts are completely made of stainless steel
The stainless steel spiral staircase comprises beech wood steps plated with a 2 mm satinised stainless steel plate with no visible welds. The thickness of the step and riser can vary (42-52 mm) depending on the diameter of the staircase.
The metal parts are completely made of stainless steel with no welds and are assembled only through mechanical fastenings. The finish can be polished or satinised except for the steps that can only be supplied with satinised finish.
