A successful northern company is looking to expand further on Teesside after winning work on a giant factory under construction at Teesworks.

Firth Steels has secured the deal to provide profiled steel for the £650million SeAH Wind monopile manufacturing facility at South Bank.

The company is manufacturing around 200,000sq metres of profiled steel which will form the roofing and wall covering on the half-mile-long building, which will be the world’s biggest monopile facility when complete and the first of its kind in the UK.

The external building envelope is being manufactured by Firth Steels at its state-of-the-art facility in West Yorkshire and the first sections have now put in place as the project achieves a further milestone.

Firth Steels, which has worked on major projects including Heathrow Terminal 5 and The Shard in London, is delivering around 15,000sq metres of steel each month.

The company has also recently completed work providing its Protex roof and wall systems on the newly built first unit on the £200million Business Park South at Teesside International Airport.

It is now looking for further expansion on Teesside in response to the rapid growth in construction at sites such as Teesworks.

James Firth, Firth Steels Managing Director, said: “Crowning our commitment to Teesworks, Firth Steels is honoured to play a pivotal role in the £650million SeAH Wind project, supplying a profiled steel building envelope for the world’s largest monopile facility. As our high-quality steel forms the building blocks of progress on Teesside, we stand ready to propel the wind revolution.

“This landmark deal not only expands our footprint but underscores our dedication to driving economic prosperity and innovation in Northern manufacturing.”

The 40m tall SeAH factory will annually produce up to 200 monopiles which form the foundations of offshore wind turbines. Hundreds are now working on the site – with 750 direct jobs in total and 1,500 forecast to come through the supply chain.

Teesworks Martin Corney CEO said: “The development of the SeAH Wind facility is now progressing at rapid pace and the high quality profiled steel provided by Firth Steels is another step forward in this process

“We are passionate about providing growth opportunities for successful businesses and it’s great to see firms looking to expand their operations on Teesside thanks to the huge projects under development at Teesworks.”

Tees Valley Mayor Ben Houchen said: “We have been clear that the regeneration of Teesworks is not just about providing new jobs on site but also in the supply chain which can benefit from supporting new developments.

“The work being carried out by Firth Steels is a fantastic example of how Teesworks is driving forward the economic prosperity of the north by providing opportunities for excellent businesses to secure new work and grow.”

South Korean manufacturer SeAH’s factory will comprise 1.13million sq ft of high-quality factory space to produce monopiles up to 120 metres in length, 15.5 metres in diameter and weighing 3,000 tonnes.

The monopiles will be transported directly from the factory to Teesworks’ new South Bank Quay before heading to the North Sea for installation using specialised pile driving equipment.

K2 Construction Management is the company with responsibility to deliver the SeAH Wind project.
