Steelwork Corrosion Control Second Edition





Introduction

Many Resident Engineers for major building projects nowadays echo the

sentiment that ‘Painting amounts to 10% of the job but provides 90% of

the problems.’ Yet at the same time there are, unquestionably, large areas

of coated steelwork withstanding the most adverse conditions for surprisingly

long periods. A typical example is the coating of offshore platforms in

the North Sea. Even in less exotic circumstances, for example bridge structures

inland, engineers have successfully extended repainting cycles by

as much as three times compared with practices of only thirty years ago. The

majority of coatings used nowadays have considerably improved properties

over the materials used then. However, this is not the sole reason

for the success. The following factors have become even more important than previously:
