During last a few years, steel companies have been suffered from economic recession, but the demands for galvanized steel sheets have been steadily increased from the industries. Responding to the market request, there have been significant efforts in galvanizing technologies and new product developments. In this paper, the recent progress of galvanizing and coil coating facilities, new product activities are described regarding automotive, appliance and construction markets in South Korea. As for automotive application, new products and process have been discussed such as AHSS developments, galvanizing on AHSS, HPF and TWIP steel, core equipments. To improve corrosion resistance especially for construction materials, Zn-55% Al coated steel sheets are popular, also Zn-Mg-Al coated steel sheets have been just developed with enhanced cut-edge protection. For electric appliances, various types of coated steel with high functional properties have been developed or developing such as black resin coating, UV-cured coating, decorative coating and so on. In addition, the prospects for future developments are discussed briefly.
