1.Brief introduction of Gi coils:
Gicoils are widely used in building industry, thecoating consists of the 55% alumina, 43% zinc, 2% silicon and other elements.
Products should be stored in a dry, ventilated, clean and neat environment.
Generally, the thickness is 0.14 ~ 1.5 mm and width is between 800mm and
1250 mm. The maximum zinc content can reach80g/sq.m.
2.Gi coils application:
GI coils are mainly used in construction, thelight industry, the automobile, agriculture, animal husbandry, andfishery industry and commercial business , etc. In constructionindustry, it is mainly used to make roof board and grill forindustrial and civilian buildings; In light industry, it is mainlyused to make casing of household electric appliances, civiliansmoke stack; In automobile industry, it is mainly used to make theparts of the automobiles; In agriculture, animal husbandry andfishery industry, it is mainly used to make the packing equipment.The skin-passed galvanized steel in coils with zero spangle islargely used as the base metal of the color-coated steelsheets.
