Galvanized sheet is cold rolled sheet covered with a milled zinc coating on both sides for increased corrosion resistance. Coatings can be applied in a variety of ways, but in industry the recommended method is hot dip galvanizing.
G is hot dipped galvanized
A is hot dipped galvanealed
60 is not necessarily the thickness, it relates to the weight of the coating. 60 is 0.60 ounces per square foot (G or A 50 is 0.50 ounces per square foot). This results in an 'average' thickness of 0.0005 inches.
WHAT ARE COATING WEIGHTS?
Zinc coating weights are measured in ounces per square foot and range from G90 to G60, G40, and G30 galvanized steel. G90 galvanized steel has a longer service life than G60, G40, and G30 galvanized steel, because G90 galvanized steel has a heavier coating weight of zinc applied to it at 0.90 oz/ft^2 as opposed to G60 galvanized steel at .060 ox/ft^2 and so on.
Application
G60 Galvanized steel coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery industries. Such as building roof, highway guardrail, sheet metal processing, roof grille, home appliance shell, ventilation pipe, chimney, kitchenware, food storage and transportation, meat, aquatic products frozen processing, etc.
