About this book

The demand for galvanized fasteners to extend the life of equipment such as fishing vessels makes this illustrated introduction to hot-dip galvanizing an important addition to the bookshelves of works managers, government officials and field project officers. The first section describes wet, dry and "old dry" processes of hot-dip galvanizing, including health and safety, principles and benefits, equipment, materials, power supply, maintenance, and quality control. The processes are illustrated with flow diagrams and there are tables to compare the relative benefits of the different options. The second section covers the specification and costing for a galvanizing plant once the market requirements have been established. There are also design recommendations and lists of further reading, advisory services and relevant standards.
