Semi-finished products

Our integrated steelmaking site at Scunthorpe produces a variety of semi-finished products to suit our customers’ rolling requirements for long, structural or general engineering products.

Our steel is produced through the basic oxygen steelmaking (BOS) process, and can then be refined as appropriate in a ladle arc furnace and vacuum degasser facilities.

These processes control the steel temperatures and chemistries extremely tightly, ensuring our wide range of steel grades meet the most demanding customer requirements.

Our slabs, blooms and billets are continuously cast in sequences and the steel is fully shrouded between the ladle and the tundish and for slabs and blooms, between tundish and mould. Hood cooling may also be used for slabs and blooms to remove hydrogen, depending on the hydrogen content and specification required. On completion, our billets are identified to cast level, while blooms and slabs are uniquely-identified to ensure traceability.

British Steel is accredited to both ISO 9001:2015 for our quality management system and ISO 14001:2015 for our environmental management system. Our steelmaking and casting processes also hold ABS, BV, CCS, DNV, LRS and RINA shipbuilding accreditations.

In addition to verifying the chemical composition and segregation of our steel, we have well-equipped laboratories onsite where other tests can be conducted as required.
