Lincolnshire County Council and North East Lincolnshire Council have joined North Lincolnshire Council in signing up to the UK Steel Charter.
The charter is a UK Steel initiative that seeks to promote the use of quality British steel in construction projects.
Cllr Rob Waltham, leader of North Lincolnshire Council, said: “Scunthorpe has hundreds of years of steelmaking history and we make some of the highest quality steel in the world at our works.
“By signing up to this charter, our three councils are agreeing to take practical steps to maximise the opportunities for UK steel producers, including those in Greater Lincolnshire.
“Despite the challenging times, I’m sure that together with our colleagues in Lincolnshire and North East Lincolnshire, and with extensive support from the Government and the passionate workers at British Steel, we can keep steelmaking in North Lincolnshire.”
Cllr Martin Hill, leader of Lincolnshire County Council, said: “We’re proud to support our colleagues in North Lincolnshire and sign up to the UK Steel Charter.
“The manufacture of British steel products isn’t just important to Greater Lincolnshire – it also makes a significant contribution to the national economy, worth around £9.5bn a year.
“It’s vital we secure the future of the industry and work towards a brighter future for Scunthorpe’s steelworks and its workers.”
Cllr Philip Jackson, leader of North East Lincolnshire Council, added: “North East Lincolnshire is ready to play its part in strengthening the UK’s steel industry.
“Like our neighbouring councils, we’ll do our utmost to promote the use of UK-produced steel in construction and infrastructure projects, supporting highly paid, skilled manufacturing jobs and training opportunities in Greater Lincolnshire’s communities.”
