Teesside Steelworks

The Teesside Steelworks was a large steelworks that formed a continuous stretch along the south bank of the River Tees from the towns of Middlesbrough to Redcar in North Yorkshire, England. At its height there were 91 blast furnaces within a 10-mile radius of the area. By the early 1990s, when No.4 furnace at Cleveland Iron closed there was only one left on Teesside. Opened in 1979 and located near the mouth of the River Tees, the Redcar blast furnace was the second largest in Europe. The majority of the steelworks, including the Redcar blast furnace, Redcar and South Bank coke ovens and the BOS plant at Lackenby closed in 2015. The Teesside Beam Mill and some support services still operate at the Lackenby part of the site. On 1 October 2022, the Basic Oxygen Steelmaking (BOS) Plant at Lackenby was demolished in one of the largest single explosive demolition operations in the country in 75 years.
