Stair Details

  • 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.

The Associates Stairs usin g screws to join the steel framewoks and perforated stepping, and also weld to join each steel frame.  To make the surface clear and smoother, the stairs painted with Duko then applied damping finishing. 151770
