Galvanized steel coil, thin steel sheets that are dipped into a molten zinc bath so that a layer of zinc adheres to their surface. Currently it is mainly produced by the continuous galvanizing process, whereby rolls of steel sheet are continuously dipped into a bath of molten zinc to make a galvanized steel sheet; alloyed galvanized steel sheet. This steel is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to around 500°C to produce an alloy of zinc and iron.
Transportation: Auto Panel; Carriage Panel;
plastic film + water proof paper + steel plate+ packing steel strip
13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
The cost of hot-dip galvanizing is lower than that of other coatings also with high quality.
The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Every part of the plated piece can be galvanized, and is fully protected even in depressions, sharp corners, and hidden places.
Save Time and Energy
Galvanizing process is faster than other coating methods.
Gi coil with good paint adhesion and weldability
Galvanized steel coil is widely used in ship, automobile, Bridges, buildings, machinery, pressure vessels and other manufacturing industries.
