With the vigorous development of construction, home appliances and automobile industry, China’s galvanized industry is facing unprecedented opportunities and huge market. Nearly 20 years of continuous hot-dip galvanized steel technology, equipment and the corresponding control means all have great development, helping the galvanized steel sheet meet the harsh requirements of car panels and appliance board, and thus has a great replacement of the potential with its electro-galvanized alloy steel with cheap, excellent corrosion resistance.
High surface quality, high strength and high deep drawability are the essential basic conditions of car panels, the surface quality of the coating is directly related to the surface roughness, the cleanliness, the chemical composition of the strip and its stamping formability. Meanwhile, CAMELSTEEL technical staff also shows that the hot-dip process, zinc liquid composition and hot-dip equipment are also an important factor of effecting the surface quality of the coating. High strength and high punching are closely related to the chemical composition, physical properties, heat treatment and hot-dip properties of hot-dip galvanized substrates.
