steel coil

Galvanized steel coil is a type of metal coil that has a layer of zinc coated on the surface of the steel plate through hotdip galvanizing or electroplating process. The main purpose is to provide excellent corrosion resistance performance, which is widely used in construction, automotive, household appliances and other industries.Background Galvanized steel coil is an extremely important basic material in modern industry. It is made of cold-rolled or hot-rolled steel coil as the substrate, which has surface treatment and then plated with a layer of zinc metal. This layer of zinc not only isolates the direct contact between steel and air and moisture but also corrodes itself prefially through the "sacrificial anode" electrochemical principle to protect the internal steel, thus greatly extending the service life of the material. At present, the mainstream production is continuous hot-dip galvanizing, that is, the coiled steel plates are continuously immersed in molten zinc to form a uniform and strongly adherent zinc layer. In to ordinary galvanized coils, there are also derivative products such as alloyed galvanized and coated galvanized to meet different scene needs. Core features and advantagesExtremely strong corrosion resistance: the zinc layer effectively prevents oxidation and rust, especially suitable for humid, outdoor environments. Good processing performance: It has excellent ductility, welability and formability, suitable for stamping, bending and other processing methods. Aesthetic and durable: The surface is smooth and bright, with both decorative and practical properties and it does not easily change color over long-term use.
