A winding staircase in the form of a two-string staircase is the superior alternative to a tank staircase. Larger structural elements or entire modules can be delivered to the building site pre-fabricated. It is attached to the tank via various brackets (included in the scope of delivery if so agreed) and according to structural necessity (e. g. in the vicinity of the landings).

It is true that this kind of winding staircase is more complex to manufacture but they are usually easier to install.

In the event of an early order, it is possible to determine the connectionpoints during the planning phase in cooperation with the tank manufacturer. This has the advantage that the installation of the connection elements can take place during the manufacture of the tank, thus completely removing the need for any welding work on the building site.
