Driving Factors

The need for massive amounts of steel rebar to maintain the structural integrity and longevity of South Korea's infrastructure is being driven by the country's rapid urbanization and ongoing increase in infrastructure development projects, such as bridges, highways, and public transportation systems. Additionally, the increasing demand for building structures that can withstand earthquakes is providing a positive outlook for the market. Steel rebar is frequently used in disaster-resilient construction because it provides the best strength and can tolerate seismic forces. Accordingly, a growing number of builders and developers are utilizing environmentally friendly building techniques, such as using steel rebar because of its recyclable nature and energy-efficient manufacturing process. In addition, ongoing developments in the technology used to manufacture steel rebar are producing rebar types that are both corrosion-resistant and extremely strong. These developments meet the changing demands of the construction industry by providing better performance and durability.

Restraining Factors

Chinese exporters who provide cheaper steel products are posing a greater threat to South Korean steelmakers. Especially in Southeast Asia, the Middle East, and Latin America, this flood of low-cost imports has put pressure on domestic prices and market share. The competitive environment is still difficult to navigate despite efforts to stand out through quality and legal measures.

Market Segmentation

The South Korea Steel Rebar Market share is classified into product type and process.

• The deformed segment held a significant share in 2024 and is expected to grow at a significant CAGR during the forecast period.

The South Korea steel rebar market is segmented by product type into deformed and mild. Among these, the deformed segment held a significant share in 2024 and is expected to grow at a significant CAGR during the forecast period. This kind of rebar has surface protrusions like lugs or ribs that improve its mechanical anchoring and cement bond with concrete. Because of these characteristics, deformed rebar is perfect for high-stress applications, such as building bridges, tunnels, high-rise structures, and other vital infrastructure projects. The preference for deformed rebar is further fueled by South Korea's growing need for strong, earthquake-resistant structures.

• The electric arc furnace segment held a significant share in 2024 and is expected to grow at a significant CAGR during the forecast period.

The South Korea steel rebar market is segmented by process into basic oxygen steelmaking and electric arc furnace. Among these, the electric arc furnace segment held a significant share in 2024 and is expected to grow at a significant CAGR during the forecast period. EAF is more popular than basic oxygen steelmaking because it uses less energy, can recycle scrap metal, and produces fewer carbon emissions. Major steel producers use the technique extensively to satisfy regulatory requirements and sustainability goals.
