Galvanized steel strip is also called hot-dip zinc or hot-dipped galvanizing. It is an effective way of metal anti-corrosion, mainly used in the industries of metal structure facilities. De-rusted steel is dipped in to 500 °C zinc liquid and coated with zinc which provides corrosion protection.
Production process: pickling-washing-adding zinc liquid-stoving-galvanized-cooling-passivation-flattening-finishing. Galvanizing has a history of 140 years since it is used in industry by Frenchman in 1836. The large-scale development of galvanizing is in the last 30 years with the development of cold-strip steel.
Galvanized steel based on cold rolled steel strip has excellent machining performance and high stamping. It is beautiful with smooth surface, accurate size,flat panel and well-distributed spangle and stored for a long time after passivation and oiling. It is the good base metal for PPGI after surface treatment.
1.Galvanized strip steel is commonly used to make steel tube and pipe, such as plastic pipe, water conduit , heating pipe, gas pipe; Can also be used in construction, light industry, automobile, agriculture and animal husbandry, fishery and commercial industries.
2.Construction industry is mainly used in the manufacture of anti-corrosion of industrial and civil architecture roofing panels, roof grille, etc.; Light industries with its manufacturing home appliance shell, civil chimney, kitchen utensils, such as corrosion resistant parts of auto industry is mainly used in manufacturing cars, etc.; Animal husbandry, fishery mainly used for food storage, meat and aquatic products frozen processing equipment, etc.; Business mainly used as material storage and transportation, packaging equipment, etc.
