Bridges & infra projects

De Koninggroep bridges & infra projects – blasting and preserving large steel constructions

De Koninggroep furthermore executes the abrasive blasting and preservation of large steel constructions, such as bridges and lock complexes. Due to their size, these objects are frequently treated on location. De Koning designs and constructs tailor-made screening and accessibility structures for these occasions, which minimise public and environmental nuisance.


Successful large-scale preservation projects

Amongst other projects, we executed the following preservation projects to the complete satisfaction of our customers:

Also for small preservation projects

Also for smaller bridges and removable objects, De Koning is your preservation specialist. Objects of a maximum dimension of 23 x 10 x 10 metres (l/w/h) are preserved in a climatologically optimised environment in our blasting and painting hall in Oosterhout.
