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.

"Unidentified Flying Objects," not "UFOs" or "Flying Saucers" Authority work is the linchpin of the library catalog. As the author puts it, "Without authority control, the burden is placed on the user to think of all the possible forms a cataloger might have used to give access in the catalog to a given author or subject." If a subject is not sorted by its authorized heading, then the library and its users and staff are left without a system and ultimately the cost of an unsatisfied user. From one of the preeminent experts in the field, this is the step-by-step guide for ensuring that your library and staff are creating and maintaining authority records with the end user in mind. Comprehensive and definitive, Maxwell's Guide to Authority Work is a must-have. In this readable text, authority work is broken down to its most basic components so that you can trace and follow the preparation of a complete authority record. Helpful illustrations identify the key characteristics of good authority records, common acronyms are defined, and cross-references throughout reinforce material. Step-by-step, you'll learn how to: Form and record uniform access points Keep thorough and accurate records Share information in an environment of international databases and cooperative cataloging The authoritative tool for making certain a person, author, corporate body, organization, book, or other media is appropriately classified under its authority name, subject, and form, Maxwell's should be part of any library's toolbox.
