Z275 Galvanized Steel Coil with big spangle

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.

The surface oxidation resistance of galvanized steel coil is strong, which can strengthen the anti-corrosion penetration ability of parts.

1. Low processing cost.
2. It is durable.
3. The durability of the coating is reliable.
4. The coating has strong toughness.
5. Every part of the plated parts can be plated with zinc, which can be fully protected even in depressions, sharp corners and hidden places.
6. The galvanizing process is faster than other coating construction methods, and the time required for painting on the construction site after installation can be avoided.
7. In general, the cost of hot dip zinc is lower than that of applying other protective coatings.
8. The inspection is simple and convenient: the hot dip zinc layer can be tested visually and by a simple nondestructive coating thickness table.
