Hot dipped galvanized steel coil has strong corrosion resistance. It can prevent the surface of steel plate from corrosion and prolong its service life.
Moreover, the galvanized coil looks clean, more beautiful and adds decoration. Hot dip galvanized steel coil is an effective metal anti-corrosion method, which is mainly used in metal structures and facilities of various industries. Immerse the derusted steel parts into molten zinc solution at about 500°C，so that the surface of the steel parts is attached with zinc layer, thus achieving the purpose of anti-corrosion. Hot dip galvanizing process flow:
pickling finished products, washing with water, adding plating aid solution,drying, hanging plating, cooling, medicating, cleaning, polishing and hot dip galvanizing.
Z275 refers to a specific coating weight of galvanized steel. It indicates that the steel has been hot-dip galvanized with a total coating weight of 275 grams per square meter.
