Vertical ladders are the ideal solution for routing cables and lines vertically. Typical areas of application include vertical ducts in buildings or industrial halls. The vertical ladders can be quickly and easily mounted directly on the wall or installed free-standing (STU 60/62 as well as ST 81/82) using head and foot plates, brackets or corresponding mounting accessories. The product’s strength is the way it allows cables to be attached securely in conjunction with cable clamps. The standard range includes vertical ladders in light, medium and heavy-duty designs. For truly effective cable routing, our heavy-duty vertical ladders enable you to attach cables on both sides. The system is available with perforated side rails with L, U or I profiles.

Airport Frankfurt
With almost 60 million passengers (2023), Frankfurt Airport is Germany's largest and Europe's sixth largest airport. In 2026, passenger numbers, which have fallen due to the pandemic, are expected to return to pre-crisis levels (~70.5 million) and continue to grow from then on.

Extension of the subway line U5
For decades, the current U5 subway line connected the eastern city center with the east and northeast of Berlin. Plans to extend the line to the west date back to the 1970s, but it was only with the reunification of Germany that these could be realized.

EDGE East Side Tower
The Berlin skyline is growing and another building was added in November 2023. With the 142 m high EDGE East Side Tower Berlin near ‘Warschauer Brücke’, one of Berlin's tallest buildings was built in just under 4 years. Particularly striking: the staircase-like curtain wall with almost complete glazing.

City S-Bahn S21 at Berlin Central Station
Berlin's main railway station is to be better connected to public transport. This is the goal of the construction of the new S-Bahn line S21, the so-called City S-Bahn. This line, which runs from north to south, connects the northern stations Wedding and Westhafen directly with the Central Station.
