Production process and characteristics of galvanized coils
Galvanized coil is a material made by covering the surface of steel plates with a zinc layer using an electroplating process. Its production process is relatively simple, mainly including surface treatment, drying, galvanizing and other steps. In this process, the zinc coating materials used can include pure zinc, cadmium zinc, aluminum zinc and other single or composite materials.
Galvanized coil materials have good anti-corrosion and anti-rust properties, as well as good processability and decorative properties. They are widely used in construction, home appliances and other fields.

About GNEE Team:
Since different customers require different thicknesses of galvanizing molds, how to accurately control the thickness of the zinc layer has become a major challenge for GNEE hot-dip galvanizing plants.
Different products have different galvanized film thicknesses. If there is too much galvanizing and exceeds the thickness required by the customer, zinc is one of the more expensive raw materials, which will cause cost waste; if the galvanized layer does not meet the product specifications, it will cause the customer to be unable to use it or have subsequent processing problems, leading to customer complaints about the quality. .
If the hot-dip galvanizing method can be explained in one sentence, it is to put the steel coil into a zinc bath and coat both sides of the steel coil with zinc liquid so that a thin layer of zinc can be attached to the surface of the steel plate to resist corrosion. However, in fact, to produce several tons of hot-dip galvanized steel coils, a series of complex processes are required, which successively enter the feeding area, annealing area, galvanizing area, tempering and leveling area, coating area, inspection area and Unloading area to complete hot dip galvanizing work.
