In the process of confirming materials and formability of the final products, conducting annealing to pass through melted zinc vessel and then trying to zinc plating. The plating adhesion quantity is adjusted to the customers requirement(60~720g/m2)
Introduction to the Galvanized Steel in Kibo Steel Co., In Galvanized Steel, heating Cold Rolled Coils (F / H) in a continuous hot-dip galvanized (CGL) and obtaining a predetermined material and then passing through melted zinc vessel. Not only in engineering and construction but also in many industries including automobile and electrical equipment, the use are gradually expanding.
Manufacture Process
Clean
Electrolylic Cleaning
Removing the residue rolling oil of the strip by electrolytic cleaning and fireworks for improving plating adhesion
An/Pl
Annealing / Plating
Alloying
Alloying
For the improvement of welding properties that is a weak point of GI, forming alloy layer of Zn-Fe by heating strip in the furnace at about 550℃
Main Usage
REGULAR
REGULAR SPANGLE (SR재)
On the surface of molten zinc, normally coagulated at room temperature to have the texture and luster of zinc
Main Usage: construction materials,Pipe, appliances inner plate, chassis etc.
MINI
MINI SPANGLE (SM)
During the molten zinc is coagulated on the plate surface, retarding zinc crystalline formation to form fine grain and the surface is uniform and has a beautiful appearance compared to the SR having corrosion resistance and good painting capacity
Main Usage: furniture, appliances inner and outer plate, interior, automobile inner plate
GALVA
GALVA (GA)
as the product that heats the coil suffering N-molted zinc plating in Gavaneal Furnace and forms Zn-Fe alloy layer, having a superior weldabilty and painting capacity relative to SR and SM
Main Usage: appliances, automobile inner and outer plate, painting
