- Stairs in Associates Room
This stair is located in the left side of Associates Room as a connector of Associates room – Technical Room – Administration Room. On the first four steps, the width of the steps was made parallel to the wall resulting in the edges which are joined to the wall to be rotated abiding wall position. All of this stairs material is steel, including the structures and finishing. It’s 3,5 – 4 centimeters steel framework structures. The stair steps use perforated steel, supported by the steel framework structures. Screws, is used to join the steel framework and perforated stepping. To stick the steel frame with the bare concrete wall, we also use screws and elbows.
