Hot Rolled Steel
Manufacturing High-Quality Hot Rolled Steel Sheets with Latest Technology Hot rolled steel refers to steel sheets that have been thinned up to 6 mm by heating, pressing, and extending semi-finished steel slabs made by processing molten metal from blast furnaces. HYUNDAI STEEL possesses a production capacity of 8.5 million tons a year to manufacture high quality hot rolled steel plates through its integrated production system with latest equipment. Hot rolled products are widely used in different industries including automotive, structures and steel pipes for construction.

Product Classification/Uses

  • Automobile
    Steel sheets that are used for automotive bodies are high in strength and resistant to fatigue, which can increase overall safety and lifespan of cars. The product is highly processable that it can be easily shaped to a car design which is increasingly diversified and also has the properties appropriate for lightweight automotive bodies. It is mostly used for car frames, wheels and exteriors.
