Handbook Of Hot Dip Galvanization

Hot-dip galvanization is a method for coating steel workpieces with a protective zinc film to enhance the corrosion resistance and to improve the mechanical material properties. Hot-dip galvanized steel is the material of choice underlying many modern buildings and constructions, such as train stations, bridges and metal domes. Based on the successful German version, this edition has been adapted to include international standards, regulations and best practices. The book systematically covers all steps in hot-dip galvanization: surface pre-treatment, process and systems technology, environmental issues, and quality management. As a result, the reader finds the fundamentals as well as the most important aspects of process technology and technical equipment, alongside contributions on workpiece requirements for optimal galvanization results and methods for applying additional protective coatings to the galvanized pieces. With over 200 illustrated examples, step-by-step instructions, presentations and reference tables, this is essential reading for apprentices and professionals alike.

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.

Hot-Dip Galvanizing of Steel Structures contains practical information that is useful for both researchers in hot-dip galvanizing and engineers, designers, and inspectors. The book draws from the empirical experience and research of the authors, complementing the current state of knowledge of morphological variations of the coating and causes of coating delamination. The book includes chapters devoted to qualitative tests of the coating, and to methods of making corrections. A section describing the principle of protecting steel against corrosion through zinc coating is also provided, along with an extensive chapter on the principles of good design for hot-dip galvanizing. The chapter related to the safety of hot-dip galvanized steel structures offers a new hypothesis about the mechanism of nucleation of LMAC cracks during hot-dip galvanizing, thus enriching the knowledge regarding this phenomenon. Provides practical information on hot-dip galvanizing from a scientific-disciplinary perspective, including coverage of design principles, reliability of galvanized structures, and legal aspects Features chapters devoted to qualitative assessments of the surface treatment and methods for correcting problems Includes discussion of hot-dip galvanizing with regard to environmental aspects and sustainable development
