Dae Dong Steel began as a steel distribution business in 1973, was designated a distributor of POSCO hot-rolled products in 1975, and listed on KOSDAQ in 2002.
Building on its status as a POSCO-designated hot-rolled distributor, the company operates facilities in Pohang and Incheon that include five Coil Service Center lines, producing primary steel materials and surface-treated steel.
The Pohang plant, located near POSCO's own facility, reduces logistics costs, while the Incheon plant lowers import transport costs, together underpinning the company's cost competitiveness.
Its product portfolio spans hot-rolled sheet, plate, checkered plate and skelp used in construction materials, pressure vessels, automotive parts, steel pipe, line pipe and corrosion-resistant steel sheet, supplied for shipbuilding, general structural and welded structural applications.
The company also provides steel-cutting processing services, adding value beyond simple distribution. Competitively, POSCO's hot-rolled distributorship network includes roughly eight regionally divided companies, including Dae Dong Steel, resulting in constant price and volume competition.
Dae Dong Steel itself does not manufacture steel pipe directly; rather, it mainly produces and supplies hot-rolled coil, the primary raw material for steel pipe, which places it in the raw-material supply chain whenever gas pipeline or energy pipe projects draw attention.
Given this business structure, earnings are directly exposed to the cycle of downstream demand industries such as construction, shipbuilding and automotive, as well as to POSCO's raw material pricing policy.
