New steel bridges

The high strength of the material towards pressure and tensile forces in combination with appropriate protection against corrosion facilitates bridge constructions with a lifetime of more than 100 years. In this context, the material proves its remarkable versatility.

Our experienced production staff pre-fabriacte of it absoltuely precise bridge components such as cables, profiles, sheets or carriers – according to requirement either hot-dip galvanised or coated. At the construction site, the components will just have to be hoisted. This considerably saves time and resources.

Bridge renovation

Bridge constructions are constantly exposed to weather. Frost and de-icing salt cycles as well as increasing heavy-duty traffic can press hard on steel and steel composite bridges in the course of time.

In the long run, they lose stability and turn into a dangerous hazard for road and rail traffic. Renovation measures, however, will substantially increase the lifetime of many constructions.

Prior to a renovation, X-ray technology will provide us with a clear overview of the bridge's condition.

In this way, we can precisely determine the parts that are damaged and whether they can be overhauled or need to be replaced.

Bridge reinforcement

Most of the bridges in Germany originate from the 1960's and 1970's, some of them are even significantly older.

The planners of the time could not foresee the enormous increase in traffic with its large proportion of heavy-duty traffic as well as the constantly increasing weight of new cars.

Steel reinforcements make it possible to adapt existing bridge constructions to these load requirements of our time and make them future-proof.

They can also decisively increase the useful life of bridges with decreasing load-bearing capacities.
