Introduction – Hot dip galvanizing is cleaned and painted for both beautification and protection. This coated galvanizing system is commonly called a Duplex System. In order for coatings to adhere and provide the desired ser...
Introduction – A number of different coating systems can be applied to galvanizing for both beautification and protection. When galvanizing is coated, the longevity of the corrosion protection system is greater than the sum ...

This article was written by KTA’s Tom Neal & Doug Reardon Introduction – The controls required for the hot-dip galvanizing process are described in Topic 1 of this series. In addition to monitoring the galvanizing proce...
Introduction – Hot dip galvanizing (HDG) of iron and steel results in a durable layer of corrosion protection that often exceeds the performance of liquid applied coatings. But despite the metallurgical reaction that result...
Introduction – Galvanizing is the application of a zinc coating to iron and steel by the hot dipping process. The process involves the dipping of both fabricated and unfabricated pieces into hot molten zinc, usually about 840° F (...
Powder coating metallic surfaces for corrosion protection and aesthetic purposes has grown by leaps and bound in the United States and more so in other parts of the world. The use of powder coating on aluminum and steel shee...
There are several methods by which a coating can protect steel from corrosion. One of the most effective methods is by providing galvanic protection. Galvanic protection works by covering the steel surface with a metal that will ...
Galvanizing is the application of a zinc layer to steel by a variety of methods such as hot dip, continuous or electro-deposition. In many instances galvanized steel is not painted since the service life of galvanizing alone typi...
Bare galvanizing provides excellent corrosion protection at a pH between 7 and 13, but corrosion of the zinc increases as the pH becomes more acidic (less than 7), or more alkaline (greater than 13). When galvanizing is exposed t...
