The demand for more durable fasteners to extend the life of equipment such as fishing vessels makes this illustrated introduction to hot-dip galvanizing an invaluable addition to the bookshelves of works managers, engineers, government officials and field project officers.
Hot-dip galvanizing is a cost-effective method of protecting cast iron or steel components from corrosion by coating them in zinc, thereby increasing the life of nuts, bolts and other items normally exposed to the elements.
The first section of this book 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 and the best method has been selected.
