The continuous galvanizing cold rolled coil is a thin steel plate with a thickness not greater than 6 mm, usually less than 3 mm, but due to the wide width, it needs to be rolled with a large rolling mill.
The width of the coiled steel strip is not more than 0.2 meters; the rolling mill used is small. Of course, the price of the galvanized steel coil is more expensive than the strip steel when the same material and the same thickness are used.
After continuous galvanizing cold rolled coil passes through the zinc bath, galvanizing will be performed on the surface of the continuous steel strip (coil). The coil runs at about 600 feet per minute.
When the coil leaves the zinc bath, it takes away an extra layer of molten zinc. Use high-pressure air (air knife) to remove excess zinc to form the desired thickness.
