Description:

Corrosion of the coating for the 55Al-Zn product is therefore not the uniform-thinning process as it is for a galvanized coating. During the early stages of the product life, the aluminum-rich dendrites stay fairly much unaffected in most environments. In a sense, the aluminum-rich dendrites perform like a barrier coating, while the zinc-rich areas provide the galvanic protection that is needed to minimize the tendency for rust staining at sheared edges and other areas of exposed steel. Because the corrosion resistance depends very much on the microstructural features of the coating, it is more important to have the right microstructure than a thick coating. It has been found that in order to achieve the desired microstructure during production, the coating thickness must not be too thin. For this reason, the most common coating designations for product to be used outdoors in the environment are AZ50, AZ55, and AZ60, as described in ASTM A792/A 792M Specification. The AZ50 coating is approximately as thick as a G90 galvanized coating.
