The value of possible production is D8 - D58, 6-12 in length and the yearly production reaches at 2 million tons. The Korea Steel, Inc. produces not only for those deformed bars that are used in the general construction but also produces the high tension deformed bars that are used in the atomic power plant, building to perform its role as the cornerstone of the national development. SECTION STEEL For it has simple structural organization and high intensity, the angle that is used in the assembly types and general iron structures is ever increasing its demands in the entire fields of domestic industry. FORGED STEEL Equipped with the large scale of forged steel facility such as 2,500 tons oil pressure press and so forth, it produces large-size forged steel products of fine quality in the 100,000 tons yearly. It is used as a partial material of shipbuilding, general industrial machinery, and generator plant and so forth, and it is recognized for its excellent quality by product export along with the approval of various classification association (GL, BV, DNV, KR, LR, NK). STEEL PIPE From the cutting of hot coil to the set, welding, to coating processing, the steel plate that produced by the straight pipe processing is being produced with variety of sizes for 150,000 tons per year. From the steel plate for general pipe, to steel plate for structure, to the steel plate for special pipe, it has produced an excellent performance not only in the family use but also the industrial pipe works. Further, through the perfect inspection, satisfactory products are produced and supplied. ROUND BAR Round bar is used not only the concrete supplementary functions in the construction, but also in the overall industry like industrial machine parts. It is equipped with the system that can produce and supply only the proper products that are fitted to the needs of customers.
