Bridges


 

Application

Among the different constructive approaches to pedestrian and bicycle, car and railway bridges, designs based on structural hollow sections in recent years have turned out to be sustainable alternatives to conventional building principles, i.e. to concrete structures. Lean design and extraordinary load to weight ratio, easy visual inspection and corrosion protection are among the many advantages of steel structures in bridge building.

 

Challenges

In exposed locations and natural surroundings, bridges may quite frequently interfere with the natural or urban environment. In order to design them as lean and functional as possible, the use of structural hollow sections is a true alternative to the bulky design of concrete structures.

 

Products and Solutions

Using the wide scope of available diameters, wallthicknesses and grades in Vallourec's MSH sections program, the structure may be adapted to the leanest design possible - highly functional with the least visual impact on the surroundings and even an aesthetic quality as a landmark building or conceptionally integrated work or engineering art.
