Dongkuk Steel, First Production of New Shape for Premium Heavy Plate Brand 'DK-LP Plate'

[Asia Economy Reporter Hwang Yoon-joo] Dongkuk Steel has produced initial batches of two new shapes of its premium heterogeneous thickness heavy plate brand, 'DK-LP Plate.'

'DK-LP Plate' is Dongkuk Steel's premium heavy plate brand that allows the application of varying thicknesses within a single plate through precise strength control during rolling. This eliminates the need for additional processing, welding, or inspection during structural fabrication, enabling cost reduction, shorter lead times, and enhanced safety.

The newly developed shapes include the '3step type' model, which implements three different thicknesses in one plate, and the 'Symmetry type,' which applies a symmetrical structural heavy plate in reverse. Following a request from shipbuilding clients for additional shapes of the DK-LP Plate 2step type model, which was commercialized successfully in January, Dongkuk Steel developed and produced these new shapes.

Dongkuk Steel plans to advance product quality and optimize production methods through further consultations with shipbuilding clients and aims to proceed with full-scale commercialization this year. Additionally, the company intends to continuously expand the DK-LP Plate product lineup to meet customer demand for customized heavy plates.

In 2018, Dongkuk Steel signed a comprehensive technology agreement with JFE Steel and introduced Korea's first heavy plate 'heterogeneous thickness rolling technology.' Since then, through ongoing technical exchanges and marketing activities with shipbuilders and other customers, the company has continuously strengthened its technological competitiveness in the heavy plate sector.
