Hot dip (or hot) galvanizing is the technology to dip the pretreated original plate of carbon steel into meltedliquefied zinc to obtain a protective zinc coating.
Hot dip aluminum zinc silicon steel plate -Galvalume(Referred to GL steel plate), is steel plate to hot-dip coat aluminum (Al 55%),zinc (Zn 43.5%), silicon (Si 1.5%) alloy on the surface of the steel plate. Itis a steel matrix composite, has excellent corrosion resistance. Hot aluminumzinc alloy steel plate performs outstanding in atmospheric corrosion resistance,thermal oxidation resistance of the aluminized steel plate and electrochemicalprotection of the galvanized steel plate.
We provide two kinds of technologiesof hot dip galvanizing (galvalume) lines: "United States Steel Corp"and independently researched and developed “JJRS-Sendzimir” .

The hot - dip (aluminum) galvanizing line is a set of equipments that plating a layer of zinc or aluminum alloy on the strip while in high temperature. The production line was composed of uncoiler, welder, storage tank, degreasing section equipments, continuous annealing furnace, zinc pot, air knife, skin pass, tension leveler, oiler, shear, recoiler and other equipments. Equipped with steel chemical cleaning or high efficiency electrolytic cleaning section, optional cleaning mode combining horizontal spray with vertical immersion spray, and unique electrolytic cleaning and ejecting mixing technology, which achieve higher current efficiency and avoid secondary oil pollution of plate out of slot , liquid surface directive overflow to ensure that the electrolyte surface rarely burst air bubble, and high safety of system service.
