Most of the scaffolding structures, need internal stair towers for easy access of the heights.  Complex scaffoldings are not easily navigated and stair towers work to help with that. These are created by combining high quality stair, landing and guardrail components which are used in scaffoldings.

Landing platforms are used at regular intervals in case of cross stair towers and the height of scaffolding determines the number of landings in the structure. Stair towers have many advantages the most important one being that they increase the security quotient of the work environment. It is not only easy to navigate people but also heavy building materials. Stair towers might stretch the entire length of scaffolding height or maybe used only at a few levels in the scaffolding structure.

The diagram here illustrates a typical plan employed in stair tower construction.
