G60 Galvanized Sheet Description
The coating designation G60 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 "60" represents the thickness of zinc on the surface of the steel sheet. Galvanized steel sheets are covered with a zinc coating to provide corrosion resistance. Galvanized steel sheet G60 is coated with molten zinc. After the continuous coating process at a speed of 600 feet per minute, the excess zinc on the steel plate is removed by high-pressure air. This is to produce the desired coating thickness. The G60 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.
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.
