Stairway towers are sometimes used like emergency exit, because it’s very easy to walk along the inside of the scaffold. Scaffold stairs are in this case inside the scaffold, instead of being on the outside as usual. Scaffolding internal stairs have a maximum weight, to make a good use of them is essential to take into account their characteristics and never exceed the allowed weight. If a scaffolding stair is not well installed, it can be a risk for all the people who work at height, so, in addition to buying approved stairs it is important that its installation is correct, being completely fixed to the bars prepared to receive the stair. Scaffolding internal stairs are a main parto for the security of a scaffolding. Our scaffold stairs fit perfectly to the structure of our scaffolding and also allow that people who is working at height are not expose to falls when they are working. It is necessary that the stairs of a scaffolding be safe, preventing changes of level from the lateral or external zones. Interchangeable hooks or hanger brackets are available for different applications.Scaffolding stairs have usually two different functions, it serve as a structural element and also allow to move from one level to another safely.
