Shandong HENGZE New Material Co., Ltd. is a China galvanized steel coil supplier, provides
hot sale galvanized steel coil and
hot dip galvanized steel coil factory price. Let’s talk about what galvanized coil materials are.
a. Hot dip galvanized steel coil. A thin steel coil is immersed in a molten zinc bath to adhere a thin layer of zinc to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel coil;
b. Alloyed galvanized steel coils. This steel coil is also produced by hot dip, but immediately after it is discharged, it is heated to about 500
°C to form an alloy coating of zinc and iron. This galvanized coil has good adhesion and weldability of the coating;c. Electrogalvanized steel coils. The production of such a galvanized steel coil by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as the hot dip galvanized coil;
d. Single-sided plating and double-sided differential galvanized steel coils. Single-sided galvanized steel coil, that is, a product that is only galvanized on one side. It has better adaptability than double-sided galvanized coils in welding, painting, anti-rust treatment, processing, etc. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized coil coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized coil;
e. Alloy, composite galvanized steel coil. It is a steel coil made of zinc and other metals such as lead and zinc, or even composite plating. This steel coil has both excellent rust resistance and good coating properties. In addition to the above five types, there are also colored galvanized steel coils, printed galvanized steel coils, and polyvinyl chloride laminated galvanized steel coils. However, the most commonly used one is still hot dip galvanized coil. Galvanized steel coils can be further divided into galvanized steel coils for general use, roofing, building exterior panels, structural, tiled slabs, tensile and deep drawing.
