    Cold rolled steel coil is directly rolled into a certain thickness by rollers at normal temperature and rolled into a whole coil by a winder. Compared with hot rolled coil, cold rolled coil has bright surface and high smoothness, but it will produce more internal stress, so it is often annealed after cold rolling.

    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℃, 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.
