North Korea's heavy industry relies heavily on durable metal structures. Due to the region's diverse topography and high humidity levels, the use of cor ten steel plate has become critical for structures exposed to extreme weather cycles, reducing the need for frequent painting and maintenance.
The local manufacturing sector is characterized by a strong emphasis on self-reliance and heavy-duty industrialization. This creates a consistent demand for mild low alloy steel, which provides the necessary balance between strength and weldability for bridge construction and factory frameworks.
Currently, the industry is facing a transition toward higher efficiency materials. While traditional low carbon steels remain a staple for general fabrication, there is a growing shift toward specialized alloys that can withstand the salty coastal air of the East Sea and West Sea regions.
