Key products
Plain (Deformed) Rebar
This is a long steel bar with a circular cross-section and surface ribs designed to enhance bonding with concrete. These ribs improve the structural integrity of reinforced concrete by ensuring superior load transfer and increased strength. Primarily used in construction and civil engineering projects, this product plays a vital role in creating durable buildings and infrastructure. It is also one of the most widely utilized materials in modern construction.

Manufacturing process
Rebar manufacturing process
At Hyundai Steel’s rebar plant, semi-finished products are precisely heated in advanced natural gas furnaces to optimal temperatures. They then undergo a meticulous rolling process, including both rough and finishing stages, to produce rebar in a wide range of specifications tailored to industry needs.
Hynndai Steel's intergrated steelworks manufacture hot-rolled and cold-rolled coils, heavy plates, pipes, and lightweight automotive parts out of iron ore and coal. By melting lumps of raw materials, molten metal is generated in blast furnaces, after which it is purified in the steelmaking process and then goes on to the continuous casting process to make slabs that can also be hardened half-finished products. Those of slabs are thoroughly rolled at a high temperature (above 1,100℃) in order to make hot-rolled coils. After that, the cold-rolled coils are made by rolling the HRC (hot-rolled coils) at room temperature to process for final usage, which is mainly for lightweight automotive parts.

Hyundai Steel’s electric arc furnace uses steel scrap to manufacture sections, reinforcing bars, and railway rails that are used for buildings, bridges and railways. After melting the steel scrap to make molten metal, it is then smelted to eliminate impurities before proceeding to the continuous casting process to manufacture halffinished products, such as blooms and billets. These half-finished products can be rolled by reheating to increase their size as finished products, such as sections and reinforcing bars, in various sizes and thickness.
