Since then, it has taken the lead in Korea s steel industry, producing cold rolled steel, galvanized steel, Galvalume (GL) steel, prepainted steel, and highperformance steel. Its technological prowess and constant R&D have resulted in the introduction of a multitude of new, highquality products. Today, the company is primed to become a world leader in the field of surfacetreated, having recently completed the construction of new facilities and the Pickling Line and Tandem Cold Mill (PLTCM). With its belief in open and ethical management, it is contributing to the growth of the national economy while helping to create a more beautiful world. In the future, Union Steel will continue heightening its enterprise value through continuous management innovations that will turn it into a world s best steel company.
> About G.I > Applications About G.I Applications 04 05 Hot Dip Galvanized Steel Hotdipped galvanized steel sheets are processed by dipping coldrolled products into a hotdip galvanized pot and then plating them with zinc. The zinc s sacrificial anodes, result in excellent paintability and workability and extraordinary corrosion resistance. In 1972, Union Steel became the first Korean company to install a continuous galvanizing line; currently, we have four line in Korea. These products are widely used in home appliances and building interiors and exteriors. Home appliance Refrigerator, Washing machine, Air conditioner, Microwave oven, Heater, Audio,Automatic vending machine etc. Automobile Body, Door, Floor, Fender, Muffler, Fuel tank etc. Steel House Steel house, Roofing panel, Walling panel, Fence, Office building exterior, Deck plate, Light gage steel, Duct, Noise barrier, Cable tray, Garage door etc. etc. Base Metal for PCM, Pipe, Electric cable etc.
