For applications where strength and hardness are a must, our carbon steels have you covered. Available in low, medium and high-carbon options, our carbon steel wire rod is used by a wide array of sectors including bedding and seating, construction, and offshore, to meet their exacting requirements.
We understand that end applications will influence your steel selections and the specific mechanical and surface properties required for downstream processing. That's why our carbon steel wire rod is designed for a wide range of uses, each increasing in strength and hardness as the carbon content increases.
Our low carbon steel range is used in applications such as concrete reinforcement and fencing where longevity and durability are key.
Some of our high carbon grades are tailored to customer specific requirements to be used in more niche applications such as bedding and seating, and also for the production of cables and ropes for the oil & gas and renewables sectors.
Our team of technical experts provides dedicated support from point of enquiry and grade selection, through to after sales service. Our short-cycle rolling programme also allows us to be responsive and to deliver the steel you need just in time to meet your production schedules.
