Histeel is a steel pipe manufacturer established in 2003 through a spin-off from Hanil Steel and re-listed on the KOSPI the same year.
The company operates its headquarters and ERW/SAW pipe production lines in Dangjin, South Chungcheong Province, and a dedicated large-diameter square pipe plant in Haman, South Gyeongsang Province, while holding HISTEEL PIPE&TUBE INC, a US sales subsidiary, and Hi-Power, a heat-treatment subsidiary.
Its product lineup spans small- and mid-diameter pipes through 60-inch-class heavy-walled large-diameter pipe, serving line pipe for oil and gas transport, oil country tubular goods (OCTG), shipbuilding and industrial pipe, and seismic-resistant square pipe for construction and civil engineering, giving it a broad spread of end markets.
The Haman plant, operating since 2022, is Korea's only dedicated facility for the seismic large square pipe 'Hi-Column,' holding domestic KS D 3864 certification as well as Japan's BCR and BCP certifications that underpin its entry into the Japanese construction market.
Its customer base includes domestic and overseas construction firms, steel structure fabricators, shipbuilders, and plant operators, with exports reaching roughly 30 countries.
In the domestic pipe industry, the company competes with SeAH Steel, Husteel, and Nexteel, while US tariff policy and anti-dumping rulings remain key variables determining competitiveness in that market.
More recently, the company has been raising the share of higher value-added products such as high-manganese steel pipe and corrosion-resistant, high-strength grades to reduce exposure to raw material price swings and defend margins.
