Open staircase realized with mono tubolar steel structure, centrally fitted under the treads, semi bended steel treads with checker plate surface, and the stair railing characterized by tubolar steel newel posts, tubolar steel balusters and handrail with different diameters, welded to each other.
Classic CF is a steel spiral staircase. The treads are printed, or semi bended, and they are introduced in the central steel pole. The stair railing is characterized by one or two low steel plates connecting the steps (according to the stair diameter), which is/are welded to vertical steel bars, similar to balusters, and to a tubolar steel handrail.
Open staircase entirely realised in steel with double lateral full band laser cut stringer laterally fitted to the steps. The treads have a perforated or diamond plate step, while the stair railing is characterised by tubolar handrail and posts. There are also two horizontal tubolars, one on the top and one on the bottom edge, welded to the posts, and vertical rods welded between them.
Open staircase realized with double tubolar steel structure, fitted under the treads. The treads are in semi-bended steel with rubber footplate, or in steel sheet in checker plate, while the stair railing is characterized by tubolar steel newel posts, balusters and handrail, with different diameters, all welded to each other.
