PRODUCT DETAILS
G40 Galvanized Coil Description
The coating designation G40 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "40" represents the weight of zinc on the surface of the steel sheet.
Galvanized steel coils are covered with a zinc coating to provide corrosion resistance. G40 galvanized steel coil is a galvanized layer name or A653 standard specification specified in the hot-dip coating process galvanized (galvanized) or zinc-iron alloy (galvanized) steel sheet requirements. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.
Scope of Application
Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
