Combining vertical integration and innovative processes, 7 Steel UK champions sustainable, circular steel production
Acquired in 2025 by Sev.en Global Investments, 7 Steel UK is the nation’s leading producer of low-carbon, circular steel, transforming UK-sourced scrap into high-quality steel products. The group consists of three main divisions: manufacturing, service, and recycling.
From its cutting-edge facility in Cardiff, 7 Steel UK has the capacity to produce up to 1.2 million tonnes of crude steel annually, supporting major infrastructure, energy and construction projects across the UK and Ireland. At the heart of the company’s operations is its electric arc furnace; the cleanest and most energy-efficient steel production technology available, delivering up to 80 per cent lower CO₂ emissions compared to traditional blast furnace methods.
7 Steel UK offers a diverse range of high-performance steel products, engineered to meet the highest standards of quality, reliability and sustainability, and remains committed to shaping a low-carbon future, one recycled tonne at a time. 
Championing circularity
“We are the domestic producer of long steel here in the UK,” begins Laura Thomas, Commercial Director. “The electric arc furnace we currently use was built in 2006, and the business itself originated as a Spanish company that took over existing operations, modernised them, and established a strong presence here. We’ve now been operating in the UK for over 20 years, celebrating that milestone in 2023, and throughout that time, our focus has consistently been on producing a naturally low-carbon material. That aspect of our work has only become more relevant as sustainability takes centre stage.
“We’re proud to be the UK’s only domestic producer of reinforcing bar, with a strong market position supported by 98 per cent UK-sourced feedstock. Circularity and strengthening the UK manufacturing and construction sectors are at the heart of what we do. Our two mills produce a full range of long products: merchant bar flats and angles, plain rounds, channels, reinforcing bar, spooler coil, and wire rod for both mesh and drawing applications. Our customers fabricate these into finished products for a wide range of applications and major infrastructure projects. We’re deeply committed to being part of key UK projects and to supporting the wider national infrastructure. Everything we do is driven by our customers, by sustainability, and by the need to future-proof our industry.”
Low-carbon steel making
Indeed, 7 Steel UK takes the principles of the circular economy as a working philosophy. Its activities are developed according to these principles and steel is one of the most recyclable and recycled materials in the world.
“The main change since our acquisition has really been our rebrand from our previous identity to 7 Steel UK,” Laura shares. “The new owners are a family-run investment company based in Prague, and they bring a fresh perspective, strong investment backing, and a real focus on innovation and sustainable growth. While day-to-day operations haven’t changed dramatically, we now have renewed energy and opportunities to develop and future-proof the business. We’ve maintained close links with our Nordic counterparts, and under Sev.en we’re strengthening our brand, our market position, and our alignment with forward-looking, sustainable industries.”
A major step forward for the company is its hydrogen-ready furnace project, which was already in development before the new ownership and has now been fully supported by Sev.en. “That’s a significant investment for our future,” Laura elaborates, “with installation expected by the end of 2027 and into 2028. Alongside this, we’ll be upgrading our rolling mill, which will expand our product range and drive further decarbonisation once hydrogen becomes fully available.
“It’s an exciting time because Sev.en is encouraging us to bring forward ideas, opening the door to innovation, continuous improvement, and new business development. Another key priority is strengthening our supply chain resilience, particularly around scrap, which is our main raw material. We’re enhancing our upstream operations in scrap collection to secure a more stable, sustainable supply, while still working closely with our trusted partners.
“At the same time, we’re continuing to support our existing markets and customers while exploring opportunities to develop new products and possibly expand our reach where it makes sense. Ultimately, we’re driven by our customers’ needs, by sustainability, and by ensuring we’re ready for the future of low-carbon steelmaking.”
Committed and consistent
As the Head of Sustainability and Public Affairs, Gabriella Nizam leads a team that contributes to 7 Steel UK’s sustainable production and low carbon recycled steel manufacturing. “The purpose of installing our shredder was twofold,” Gabriella explains. “We wanted to improve the quality of scrap going into the melt shop and to make the process more energy efficient. By aggregating and sorting scrap into more uniform shapes and sizes, we can melt it more effectively, consuming less electricity and reducing our carbon footprint. The shredder allows us to process a wider range of scrap types and ensure that what enters the furnace is of higher, more consistent quality.
“What really sets 7 Steel UK apart is that we’re a vertically integrated steel company. We’re heavily reliant on scrap as our primary feedstock, around 30 per cent of which currently comes from our own scrap yards, but we have plans to grow that share over time. It’s not about reaching 100 per cent, but about improving control, quality, and circularity. We’re increasingly working with customers ahead of demolition projects to identify scrap that can be recycled through our own facilities, melted, and ultimately returned to market as new steel. That approach strengthens our supply chain resilience and supports a circular economy model. More than just producing steel, we’re providing a service, creating closed-loop systems that enhance traceability, sustainability, and the retention of value within the UK steel industry.”
Looking to the future, Laura shares 7 Steel UK’s plans to continue to be a strong and reliable supplier in what is undoubtedly a challenging market. “Demand is tough, and the construction sector is going through a difficult phase, but our focus remains on supporting our customers day-to-day and delivering what they need,” she affirms. “We’re also strengthening our vertical integration across the business, ensuring that both our upstream and downstream operations are aligned. Most importantly, we want our customers and partners to know that 7 Steel UK is here for the long term: committed, consistent, and fully invested in the UK market.”
Service-oriented approach
In terms of the company’s environmental focus, Gabriella shares 7 Steel UK’s approach. “Our focus goes beyond decarbonisation, though that remains a focus through process optimisation, efficiency improvements, and eventually fuel switching, like the hydrogen-ready furnace we’re building. On an industrial scale, hydrogen availability is still a challenge, so the immediate benefits also include expanded product opportunities for the market. Beyond decarbonisation, we’re considering broader environmental and social factors, such as biodiversity, water management, and our role as a responsible business both internally with employees and externally with stakeholders.
“We’re recalibrating our approach considering UK policy uncertainty, electricity price pressures, trade exposure, and the need to support domestic production. Our goal is to future-proof 7 Steel UK while driving demand for low-carbon, circular steel. We aim to be recognised as the UK leader in low-carbon, circular steel, supporting major infrastructure projects like HS2 and Crossrail, and aligning with government strategies on industrial growth and clean energy. Our vertically integrated, service-oriented approach ensures we can meet the needs of the domestic market sustainably and efficiently.
“It’s really about refining what we do and demonstrating the value of steel beyond low carbon credentials,” Gabriella concludes. “Electric arc furnace technology gives us an advantage, but the bigger picture is national resilience, strong supply chains, jobs, and local economic value. With clear government policy, the UK can build a thriving, sustainable domestic steel industry.”
