\n What is Galvanized Steel<\/span>\n

Zinc-coated Steel for Reliable Corrosion Protection<\/h2>\n\n

\n Galvanized steel is produced by coating steel with a protective zinc\n layer through a hot-dip galvanizing process. The zinc layer helps\n protect the steel substrate from rust and oxidation.\n <\/p>\n\n

\n It is widely used in construction, roofing, structural parts,\n ventilation systems, industrial components and general fabrication.\n <\/p>\n\n

    \n
  • Strong corrosion resistance<\/li>\n
  • Good forming and processing performance<\/li>\n
  • Multiple spangle and surface options<\/li>\n
  • Suitable for indoor and outdoor applications<\/li>\n
  • Reliable material for construction supply<\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n

    Process Overview<\/div>\n\n
    \n

    Continuous Line Workflow<\/h3>\n\n

    \n The hot-dip galvanizing line integrates strip preparation, annealing, zinc coating, cooling and finishing into one continuous production workflow.\n <\/p>\n\n

    Full process steps<\/div>\n\n
    \n
    \n
    01<\/div>\n
    \n

    Uncoiler No.1 \/ No.2<\/h4>\n

    Steel coils are loaded and uncoiled to provide a continuous strip feed for the production line.<\/p>\n <\/div>\n <\/div>\n

    \n
    02<\/div>\n
    \n

    Welder<\/h4>\n

    The tail of one coil is welded to the head of the next coil to maintain continuous production.<\/p>\n <\/div>\n <\/div>\n

    \n
    03<\/div>\n
    \n

    Entry Looper<\/h4>\n

    The entry looper stores strip length temporarily, allowing welding and coil changes without stopping the line.<\/p>\n <\/div>\n <\/div>\n

    \n
    04<\/div>\n
    \n

    Pre-treatment<\/h4>\n

    The strip surface is cleaned and prepared to remove oil, dust and oxides before heat treatment.<\/p>\n <\/div>\n <\/div>\n

    \n
    05<\/div>\n
    \n

    Annealing Furnace<\/h4>\n

    The steel strip is heated under controlled conditions to improve mechanical properties and coating adhesion.<\/p>\n <\/div>\n <\/div>\n

    \n
    06<\/div>\n
    \n

    Zinc Pot<\/h4>\n

    The strip passes through the molten zinc bath to form a protective zinc coating on the steel surface.<\/p>\n <\/div>\n <\/div>\n

    \n
    07<\/div>\n
    \n

    Air Knife<\/h4>\n

    Air knives remove excess molten zinc and precisely control the final coating thickness.<\/p>\n <\/div>\n <\/div>\n

    \n
    08<\/div>\n
    \n

    Cooling Tower<\/h4>\n

    The coated strip is cooled in a controlled process to stabilize the zinc layer and surface quality.<\/p>\n <\/div>\n <\/div>\n

    \n
    09<\/div>\n
    \n

    Water Quench Tank<\/h4>\n

    The strip is further cooled through water quenching to reach the required process temperature.<\/p>\n <\/div>\n <\/div>\n

    \n
    10<\/div>\n
    \n

    Skin Pass<\/h4>\n

    A light rolling process improves surface flatness, mechanical stability and appearance.<\/p>\n <\/div>\n <\/div>\n

    \n
    11<\/div>\n
    \n

    Tension Leveler<\/h4>\n

    Tension leveling corrects strip shape and reduces waves, edge defects and residual deformation.<\/p>\n <\/div>\n <\/div>\n

    \n
    12<\/div>\n
    \n

    Passivation Coater<\/h4>\n

    A passivation layer is applied to improve corrosion resistance, storage performance and surface protection.<\/p>\n <\/div>\n <\/div>\n

    \n
    13<\/div>\n
    \n

    Exit Looper<\/h4>\n

    The exit looper stabilizes downstream speed and supports smooth transition before recoiling.<\/p>\n <\/div>\n <\/div>\n

    \n
    14<\/div>\n
    \n

    Recoiler<\/h4>\n

    The finished coated strip is recoiled into a final steel coil for packaging, storage and shipment.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n
