Material: Galvanized steel refers to steel plates that are coated with a layer of zinc to enhance their corrosion resistance. Common steel substrates include Q235 and Q345.
Application Fields: Galvanized steel is widely used in construction, automotive, household appliances, and machinery sectors. It is used to manufacture roof panels, wall panels, car bodies, appliance casings, and more, primarily to improve the corrosion resistance and lifespan of the steel.
Galvanized steel is a material with a zinc-coated surface, which can be treated through hot-dip galvanizing or electrogalvanizing. Hot-dip galvanizing involves immersing the steel plate in molten zinc, while electrogalvanizing deposits a zinc layer on the steel surface through an electrochemical reaction. Galvanized steel offers excellent corrosion resistance, strength, and toughness, making it suitable for use in various environmental conditions.
