Turun Metsänkävijät made a complete renovation of their clubhouse and build an extension to which Hi-Con provided this impressive accordion staircase.
The stairs are made of dark colored CRC i2® high performance concrete with smooth surface steps and landings. The lowest landing is supported on the wall below, the other two landings are supported on the recesses in the walls.
The width of the staircase is 1180 mm, the runs are 300 mm and the rises are 155 mm. The thickness of the stairs is only 100 mm, so even the heaviest element weighted only about 1.3 tons.
