Varieties and uses of hot-dip galvanized steel

Common hot-dip galvanized steel varieties include galvanized steel sheet and steel strip, galvanized steel wire and steel wire mesh, galvanized steel pipe, galvanized steel and structural parts, galvanized pipe fittings (malleable cast iron pipe fittings), galvanized parts, fasteners, For galvanized device products, common coatings include pure zinc coating, zinc aluminum alloy coating (zinc aluminum rare earth, zinc aluminum magnesium, zinc aluminum lead), zinc nickel alloy coating, aluminum zinc alloy coating (aluminum zinc silicon), etc. Galvanized products are widely used in construction, communications, electric power, transportation, energy, automobiles, light industry (home appliances), agriculture, animal husbandry and fishery, petrochemical and other industries. Its main uses are as follows: (1) Light industry and home appliance industry: air conditioners , TVs, washing machines, refrigerators, microwave ovens, water heaters and other household appliances shells and bottom plates, computer bottom plates and shells, civil chimneys, kitchen utensils, buckets, containers, etc. (2) Electric power and communication industry: electric power transmission tower, communication tower, cable armor tape, galvanized low carbon steel wire for communication, galvanized steel wire for steel core aluminum stranded wire, hanger, galvanized steel for suspension and fastening Stranded wire. Pole cross arm, pull wire and fasteners, various cable trays.

 (3) Construction industry: various industrial and civil buildings use light steel keel, building layer panels, corrugated boards, roof grilles, galvanized pipes for ventilation, water supply and drainage. (4) Automobile industry: automobile body, door, bottom plate, inner plate, etc. (5) Transportation industry: highway guardrails, highway isolation nets, road and highway light poles, various indicator signs, and galvanized structural parts for bridges. (6) Metallurgical and chemical industries: galvanized pipes, structural frames, and various containers for conveying various low-pressure fluids. (7) Agriculture: sprinkler irrigation pipes, light steel keels for plastic greenhouses, granaries, storage and transportation containers, farm tools, and galvanized iron wires for binding. (8) Fishery and animal husbandry: steel wire ropes for fishery and net fences for animal husbandry. The development of continuous hot-dip galvanized steel sheets in China began in the 1970s. In 1979, my country WISCO introduced the first modern continuous hot-dip galvanizing production line and color coated steel plate production line from abroad, marking the beginning of modern steel strip galvanizing technology in my country.
