U Step Staircase
Bora Yıldırım
Building Materials and Construction Components Design U Step Staircase by Bora Yıldırım U Step staircase is formed by interlocking two u-shaped square box profile pieces having different dimensions. This way, the staircase becomes self-supporting provided that the dimensions do not exceed a threshold. In-advance preparation of these pieces provides assembly convenience. Packaging and transportation of these straight pieces are also greatly simplified.
