Abstract

The sheet (7) has a set of folds that carry a flap (13) in which an opening (14) is designed to fix a slot (17) by screwing. The opening is arranged in an adapted position such that the opening cooperates with the slot by indexing. The flap and another flap are approximately arranged in a same plane. A surface is provided between the set of folds, and a plate is adapted to support steps of a set of users in a direct manner. The slot is directed in a direction of an upper floor, and a turntable (19) is arranged on the sheet. Independent claims are also included for the following: (1) a central stringboard staircase (2) a method for manufacturing a metal sheet.
