1. Hot-Dip Galvanized Steel Product Characteristics

Product	Coating Layer Structure	Characteristics	Major Usage
Zero Spangled (Minimized Spangle)		While molten zinc solidifies on the surface of the steel sheet, normal zinc crystalization is suppressed creating fine crystals. The surface is flat and has a fine appearance after painting. Paintability is superior to regular spangle products.	Furniture, office appliances, inner &outer panels of home appliances, substrates for painting, automobile inner plates, pipes, construction materials

Galvannealed		By a thermal diffusion process, steel sheet and zinc react to produce Zn-Fe alloy coating layer. Weldability and paintability is superior to galvanized steel sheets. Iron in the alloy layer enhances corrosion resistance after painting.	Inner&outer panels of home appliances and automobiles
