Kyeong Nam Steel was founded in 1990 as Samhyun Steel Industry and renamed to its current name in 1995, operating as a KOSDAQ-listed steel processing company.
The company's business model is that of a 'POSCO processing center,' receiving cold-rolled steel coils from POSCO, then shearing, cutting, and processing them for resale to automotive, home appliance, and construction end markets.
According to available sources, its major customers reportedly include ZF Sachs Korea, Koryo Welding, LG Electronics, Hyundai Mobis, and Renault Korea.
The company's production base is located in Changwon, near LG Electronics affiliate suppliers and GM Korea and Renault Korea production lines, which is cited as contributing to regional demand stability.
Its product lineup centers on cold-rolled and hot-rolled steel processed goods, and because it lacks its own steelmaking facilities and relies on POSCO for raw material, the spread between input and processed product prices is a key driver of earnings.
Given this business structure, profitability depends more on utilization rates, sales volume management, and cost competitiveness than on large capital investment.
While similar cold-rolled processing and distribution firms exist as competitors, proximity to Changwon-area automotive and appliance parts makers is cited as a relative strength. Governance entered a more stable phase in December 2025 when second-generation owner CEO Choi Seok-woo became the largest shareholder.
