Protective coatings for steel bridges. A guide for bridge and maintenance engineers

Protective coatings for steel bridges. A guide for bridge and maintenance engineers

Steel bridges comprise approximately 20% of New Zealand state highway bridges and, with the inclusion of the Auckland Harbour Bridge, represent an asset replacement value of over $2 billion.

Protective coatings are often less than one third of a millimetre in thickness and are required to protect highly stressed steel from corrosion in often aggressive marine environments.

Historically the full potential life of these coatings has not been achieved due to less than optimum coating selection, specification, application or maintenance.

The ultimate objective of this guide is to optimise the long term capital and maintenance costs of steel structures through the implementation of best practice in the selection, application and maintenance of protective coatings on steel structures.
