About the Products

Steel cord

Steel cord is a product that requires strict process control such as adhesion with rubber, strength, and fatigue resistance. It is a product often used for belts and carcasses of tires that enhances the tensile strength of tires, withstands impact from the surface of the road, functions as the framework of tires, and supports against the load imposed from the exterior.

Hyosung Advanced Materials’ steel cord is expanding its product range to high-strength products in line with the increase of electric vehicles. Also responding to customers' needs for eco-friendly products, recycled steel cord products are being developed and in the process of customer evaluation. In addition, the company is striving for technological advances in product development and production technologies.
Bead wire

Bead wire secures the carcass which withholds the internal pressure of the tire from the vehicle’s weight. It fastens the tire in place to the rim and is crucial in maneuvering drives, brakes, and steering torque to the road surface.

Hyosung Advanced Materials' Bead wire is produced in varied lengths and wire diameters and personalized accordingly to the customers’ needs.

Eco-friendly recycled Bead wire products have been developed to cater to eco-conscious needs of customers, providing immediate services to customers' specific requirements.
