What are the uses of galvanized steel coil
Galvanized steel coil: immerse the steel sheet into the molten zinc bath to make its surface adhere to a layer of zinc steel sheet. At present, the continuous galvanizing process is mainly used, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but after it is out of the groove, it is immediately heated to about 500 ℃ to form an alloy coating of zinc and iron. This kind of galvanized coil has good coating adhesion and weldability.
What are the uses of galvanized roll
However, there are also many defects in the galvanized roll, mainly including: falling off, scratching, passivation spots, zinc particles, thick edges, air knife stripes, air knife scratches, steel exposure, inclusions, mechanical damage, poor steel base performance, wavy edges, scooping, improper size, stamping, improper thickness of zinc layer, roller printing, etc.
Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grids, etc; Light industry uses it to manufacture household appliance shells, civil chimneys, kitchen utensils, etc. the automotive industry is mainly used to manufacture corrosion-resistant parts of cars, etc; Agriculture, animal husbandry and fishery are mainly used as tools for grain storage and transportation, frozen processing of meat and aquatic products, etc; Commerce is mainly used as storage and transportation of materials, packaging appliances, etc.
