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

Aluminum-zinc Coated Steel for Long-term Protection<\/h2>\n\n

\n Galvalume steel is coated with an aluminum-zinc alloy layer. The coating\n combines the barrier protection of aluminum with the sacrificial protection\n of zinc, helping improve durability in demanding environments.\n <\/p>\n\n

\n It is widely used for roofing, wall cladding, industrial buildings,\n appliances and applications that require stable corrosion resistance\n and heat resistance.\n <\/p>\n\n

    \n
  • Excellent long-term corrosion resistance<\/li>\n
  • Better heat resistance than standard galvanized steel<\/li>\n
  • Stable surface performance for roofing systems<\/li>\n
  • Suitable for outdoor and high-demand environments<\/li>\n
  • AFP, chromated, oiled and dry surface options<\/li>\n <\/ul>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n

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

    Aluminum-zinc Coating Workflow<\/h3>\n\n

    \n The galvalume line integrates strip preparation, annealing, aluminum-zinc alloy coating, cooling, surface treatment and recoiling into one continuous 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 stable strip feed for continuous galvalume production.<\/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 production 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, supporting coil change and welding 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 annealing and coating.<\/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

    Al-Zn Coating Pot<\/h4>\n

    The strip passes through the molten aluminum-zinc alloy bath to form a durable galvalume coating layer.<\/p>\n <\/div>\n <\/div>\n

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

    Air Knife<\/h4>\n

    Air knives remove excess molten coating and precisely control the final aluminum-zinc 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 aluminum-zinc alloy 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 strip flatness, surface appearance and dimensional stability.<\/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

    Surface Treatment<\/h4>\n

    AFP, chromated, oiled or dry treatment can be applied to improve storage, handling and surface performance.<\/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 galvalume strip is recoiled into steel coils for packaging, storage and shipment.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n
