DX51D Z150 Galvanized Coil Description<\/strong><\/b><\/h2>\n

Galvanized\u00a0coil is made of\u00a0a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures.\u00a0Zinc is generally represented by Z. Z is the abbreviation of English Zinc. For example, the Z80 surface zinc plating content is 80 grams per square. Z150 means that the galvanizing content is 150 grams per square meter, and so on. The number after Z indicates the average coating content at three points on both sides of the galvanized steel\u00a0in grams per square meter. The general materials of hot-dip galvanizing on the market are: Z80, Z100, Z120, Z140, Z180, Z275, etc.<\/p>\n

\nScope of Application<\/strong><\/b><\/p>\n

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.<\/p>\n
