G60 Galvanized Sheet Steel

Galvanized steel is the result of applying a protective zinc coating to steel to prevent it from rusting.

G60 galvanized sheet steel.

The galvannealed is designated with an a a40 a60. They both fall under astm a 653 a 653m. G60 0 60 183 g90 0 90 275 g115 1 15 351 g140 1 40 427. The hot dip process a653 a653m.

The g90 would be more galvanized coating than say g60. And galvanized designated with a g g40 g60. Producers buy a license to produce galvalume and galfan as specified in the corresponding patents. If it is for outdoor use or in a high moisture environment i would always specify g90 just because it seems to make a difference over time.

Additionally not all galvanized steel looks the same. I hope this helps. Hot dip coating baths react with the steel adding low levels of iron to the coating and the bath. The g60 is the most common galvanized metal and determines the amount of galvanize on the metal.

For example g60 is galvanized with a two side triple spot coating weight of at least 0 60 oz ft 2. The most common method of galvanizing steel is the hot dip galvanized process. A wide variety of galvanized g60 sheets options are available to you such as standard processing service and surface treatment. The number call out for both is the weight of the coating.

A wide variety of g60 hot dipped galvanized steel options are available to you such as cold rolled hot rolled and erw. G60 or a60 is 0 60 ounces per square foot resulting in an average thickness of about 0 0005 inches. About 48 of these are steel sheets 0 are stainless steel sheets. There are different thicknesses of zinc coating that can be applied to the steel but g60 or g90 are the two most common.

Others available upon request. Deep drawing steel and extra deep drawing steel are designations described in the astm specifications for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by. Each of the steel sheet designations is associated with unique. The size of the crystallites in the galvanized coating is called spangle and it will greatly alter the appearance of the galvanized sheets.
