This article discusses the processes involved in continuous hotdip coating of steel sheets, namely, hot and cold line processing, surface preparation, and post treatment. It outlines the properties and microstructures of metals and their alloys used in this process. The coatings considered in this article include metal coatings, such as zinc coatings, and alloy coatings, such as zinc-iron, types 1 and 2 aluminum, Zn-5AI, Zn-55AI, and lead-tin coatings.

This article describes the basic principles, processing steps, and benefits of continuous hot dip coatings. It provides useful information on the principal types of coatings applied in the hot-dip process. The types of coatings include galvanized coatings, galvannealed coatings, 55Al-Zn coating, 95Zn-Al coating, and aluminized coatings.

This article commences with a description of the applications of galvanized coatings and provides information on metallurgical characteristics, such as coating thickness and alloying elements. It examines the effect of galvanizing process on the mechanical properties of steels and briefly describes the cleaning procedures of iron and steel pieces, before galvanizing. The article discusses the different types of conventional batch galvanizing practices. Information on the galvanizing of silicon-killed steels is also presented.
