Asahi Glass (AGC) has created the world’s first glass spiral staircase, using a suspension structure.
The transparent glass steps, which are suspended in spirals, look as if they are floating in the air. This innovation is available at the AGC studio, which offers hands-on experience of AGC’s various glass products.
Glass staircases have been used in numerous facilities, but many of them have glass plates at the sides of the steps to support the entire structure. Eliminating the side glass plates could enhance the transparency of a glass staircase; however, this could not be achieved until now because of the difficulty in fixing glass steps without side plates.
With the support of Hiroshi Ota, taking charge of design planning, and Jun Sato, responsible for structural design, AGC successfully created suspended glass steps that stand unaided.
