Cables

PosCable (POSCO wire for Cable): Strong and artistic

In a suspension or cable-stayed bridge, cables transfer load applied to the superstructure to the main towers to support the bridge. For this application, POSCO’s steel wires are extensively used.They are made by twisting wires made of POSCO’s wire rods. This way they can be extremely strong: One strand of steel thinner than a straw can bear the weight of a 4.5-ton truck. The cables are highly resistant to rust when they are used over the sea, enabling the bridge to stay durable and long-lasting.
