Bridges
One main area that utilise the Metal Spray process is utilised is with regards to anti-corrosive protection of bridges. The building of bridges requires a significant investment. Due to the environments in which the bridges are located, they are often susceptible to extreme conditions that result in rust and corrosion. For this reason, a high performance, proven corrosion protection coating is often required and specified. Bridges and bridge steelwork is also very large and hence metal spraying is an ideal solution as the work can be completed on-site without the need to dismantle the structure.
