Unless a structure is fabricated from weathering steel all our projects are blasted and primed and then given an appropriate coating of protective treatment. This is an element that should not be underestimated in its importance, it is effectively the finishing touch to most structures but it is not just a decorative finish but it also gives the structure the required protection against the elements. We work closely with the manufacturers to ensure we are providing our clients with a suitable product compatible with the environmental conditions the structure will inhabit.
Whilst most of our projects require some protective treatment we also fabricate structures out of Cor-ten or weathering steel. This material structural steel with improved atmospheric corrosion resistance weathering steel forms an adherent protective rust ‘patina’, that inhibits further corrosion. The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance. Hence, a well-detailed weathering steel bridge in an appropriate environment provides an attractive, very low maintenance, economic solution.
