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

Durable Color-coated Steel for Modern Construction<\/h2>\n\n

\n PPGI (Pre-painted Galvanized Iron) is produced by coating galvanized\n steel with high-quality paint systems through continuous roller coating\n and baking processes.\n <\/p>\n\n

\n It combines excellent corrosion resistance, attractive appearance,\n lightweight structure and long-term durability, making it ideal\n for industrial and commercial applications.\n <\/p>\n\n

    \n
  • Excellent corrosion resistance<\/li>\n
  • Lightweight and easy processing<\/li>\n
  • RAL color customization support<\/li>\n
  • Long service life<\/li>\n
  • Suitable for roofing and cladding<\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n \n

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

    Continuous Color Coating Workflow<\/h3>\n\n

    \n The PPGI line integrates substrate preparation, chemical treatment, primer coating, finish coating, curing, cooling and recoiling into one continuous production workflow.\n <\/p>\n\n

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

    Uncoiler<\/h4>\n

    Steel coil is loaded and uncoiled to provide a continuous strip feed for the color coating 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 keep the line running continuously.<\/p>\n <\/div>\n <\/div>\n

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

    Entry Looper<\/h4>\n

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

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

    Degreasing<\/h4>\n

    Oil, dust and surface residues are removed from the steel strip before pretreatment and coating.<\/p>\n <\/div>\n <\/div>\n

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

    Pretreatment<\/h4>\n

    Chemical pretreatment improves paint adhesion, corrosion resistance and long-term coating performance.<\/p>\n <\/div>\n <\/div>\n

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

    Primer Coating<\/h4>\n

    Primer coating is applied to build a stable base layer and improve bonding with the finish coating.<\/p>\n <\/div>\n <\/div>\n

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

    Primer Baking Oven<\/h4>\n

    The primer layer is baked and cured under controlled temperature to form a durable base coating.<\/p>\n <\/div>\n <\/div>\n

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

    Primer Cooling<\/h4>\n

    The strip is cooled after primer baking to stabilize the coating before the finish coating stage.<\/p>\n <\/div>\n <\/div>\n

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

    Finish Coating<\/h4>\n

    The finish paint layer is applied according to the required color, gloss, texture and coating system.<\/p>\n <\/div>\n <\/div>\n

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

    Finish Baking Oven<\/h4>\n

    The finish coating is baked and cured to achieve required adhesion, durability and surface performance.<\/p>\n <\/div>\n <\/div>\n

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

    Finish Cooling<\/h4>\n

    The coated strip is cooled after finish baking to stabilize the paint film and surface quality.<\/p>\n <\/div>\n <\/div>\n

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

    Exit Looper<\/h4>\n

    The exit looper balances downstream speed and supports smooth continuous recoiling.<\/p>\n <\/div>\n <\/div>\n

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

    Recoiler<\/h4>\n

    The finished pre-painted steel strip is recoiled into PPGI coils for packaging, storage and shipment.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n
