What is Galvanized Steel Coil?<\/h2><\/div>\n\n\n\n

Galvanized steel coil is steel strip or coil where hot or cold rolled steel has been treated with zinc to prevent corrosion. Galvanizing involves giving the steel coil a zinc coating by dipping it into a molten zinc bath or through a continuous hot dip galvanizing process.<\/p>\n\n\n\n

The zinc coating acts as a barrier between the steel and the surrounding environment, preventing rust and corrosion on the steel surface. It acts as a sacrificial layer, meaning that if the coating is broken or scratched, the zinc will corrode before the steel underneath.<\/p>\n\n\n\n

Galvanized steel is typically made from mild steel, which has a carbon content of less than 0.2%. This steel is chosen because it is easy to work with and has excellent welding and forming qualities.<\/p>\n\n\n\n

GI can be formed or coated with various coatings, becoming a new hot-selling product. Such as: galvanized corrugated sheet, color-coated galvanized coil (PPGI), etc.<\/p>\n\n\n\n

Galvanized steel surface spangle<\/h3><\/div>\n\n\n\n

In previous steelmaking processes, the surface of galvanized steel coils often contained large, flower-like patterns of zinc crystals called “flakes.” Flakes resembled large, hexagonal snowflakes. While today’s galvanized steel still contains flakes, modern steel mills produce galvanized steel with flakes that are almost unnoticeable to the naked eye. This is known as minimal flake and zero flake galvanized steel.<\/p>\n\n\n\n

Galvanized Steel Coil Production<\/h2><\/div>\n\n\n\n

There are two widely used methods for applying zinc to steel coils:<\/p>\n\n\n\n

Hot dip galvanizing<\/h3><\/div>\n\n\n\n

Hot dip galvanizing (HDG)<\/a> technology involves immersing the steel strip in a bath of molten zinc to form a protective coating. Hot-dip galvanized steel coils can be produced by continuous galvanizing lines with non-oxidizing annealing furnaces (Sendzimir process and its variants) or using wet or dry fluxes (Cook-Norteman process and its variants). Continuous hot dip galvanizing lines with non-oxidizing annealing furnaces start with hot or cold rolled unannealed (hardened) steel coils. Hot dip galvanizing technology is quite common and is widely used in construction, machine building and other industries. Large steel mills and re-rolling\/coating plants use this technology.<\/p>\n\n\n\n

Electrolytic galvanizing<\/h3><\/div>\n\n\n\n

Electrolytic galvanizing<\/a> (Electrogalvanization) is an electrochemical process in which a layer of zinc is applied in an acidic or alkaline electrolyte. The main idea of \u200b\u200bthe technology is to use oxidation and reduction reactions during which electrons move through an electron transport chain while zinc ions in the electrolyte flow from the anode to the cathode. Such coatings are usually suitable for thin gauge materials; the coating thickness is usually 5-12 microns and can be precisely adapted to the product shape.<\/p>\n\n\n\n

Compared with hot-dip galvanized coatings, electrolytic zinc coatings are more plastic due to the absence of an intermediate brittle layer. The main application areas of such products include automotive, transportation and machinery manufacturing, among others.<\/p>\n\n\n\n
