Galvanized coil is a cold-rolled or hot-rolled steel coil whose surface has been treated by a hot-dip galvanizing process and has excellent corrosion resistance. By immersing a clean steel plate in molten zinc, a uniform and dense zinc layer is attached to the surface of the steel plate, thereby effectively isolating direct contact with air, moisture and other corrosive factors, and significantly extending the service life of the steel.
Material and production process
Base material: ordinary carbon structural steel, the main components are iron and carbon, and also contain a small amount of silicon, manganese, sulfur, phosphorus and other elements.
Production process: It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the plating tank with molten zinc, so that a layer of zinc adheres to the surface of the steel plate. For alloyed galvanized steel plates, they will be heated to about 500℃ immediately after leaving the tank to form an alloy film of zinc and iron.
Types and specifications
Substrate types: cold-rolled coils, hot-rolled pickled coils, etc.
Galvanized layer types: normal zinc flower coating, small zinc flower coating, zinc-iron alloy coating, etc.
Coating weight: According to demand, the coating weight has different classifications, such as Z60, Z100, Z180, etc. The specific weight needs to be determined by negotiation between the supply and demand parties.
Application field
Galvanized coils are widely used in many fields due to their excellent performance:
Construction field: used for parts in building structures, such as beams, columns, purlins, etc., as well as building roofs, walls and other parts to protect building materials from corrosion.
Automotive industry: used to manufacture parts such as automobile bodies, doors, hoods, etc., to extend the service life of automobile parts.
Home appliance field: manufacturing home appliances such as refrigerators, washing machines, air conditioners, etc., to protect the product surface and extend the service life.
Food processing: used to manufacture conveyor belts, shelves, cargo boxes, etc. of conveyor systems to ensure food quality and hygiene.
Agricultural field: manufacturing agricultural machinery and equipment, greenhouse brackets, etc., with strong corrosion resistance and long service life.
Other fields: such as shipbuilding, furniture manufacturing, oil field equipment, communication equipment and other fields, galvanized coils also play an important role.
