Steel Dynamics UK
About us
Steel Dynamics UK is one of the country's leading stainless steel stockholders and processors, supplying stainless, duplex, super duplex and lean duplex into complex and demanding supply chains across the UK and beyond. Over 3,000 tonnes of material is held at our Blackburn facility, in thicknesses from 0.5mm to 150mm and across the grade range engineers actually specify — including 304, 316, 2205, super duplex and specialist grades held as standard rather than ordered in.
Processing is what sets us apart. Every plate is processed in-house on advanced equipment, with fibre laser and waterjet cutting at the core of our capability.
Our fibre laser cells deliver fast, high-precision cutting on thinner and mid-range plate, producing clean edges with tight tolerances and minimal downstream finishing. Our waterjet capability handles thicker material and demanding grades without introducing a heat-affected zone — critical for duplex, super duplex and any application where the metallurgy must be preserved through processing. Both technologies are supported by high-definition plasma cutting, plate sawing, folding, CNC machining, bevelling and permanent marking, along with testing and inspection.
Our facility processes stainless steel only. No carbon steel runs alongside it, no shared cutting beds, no mixed handling. That single-metal environment eliminates the cross-contamination that causes stainless to fail prematurely in service — a quality requirement, not a marketing claim, and one of the reasons customers in regulated sectors trust our material to arrive as specified.
Steel Dynamics UK supplies into nuclear, aerospace and defence, energy, hydrogen, critical infrastructure and general fabrication. We were the world's first metal service centre to achieve ISO 19443 accreditation, are a founding member of the Sizewell C supply chain consortium, and operate a fully certified quality management system supporting third-party inspection, hold points and full traceability from mill to delivery. Every plate we supply is fully traceable back to its European mill of origin.
By combining broad stock availability, advanced in-house processing on a stainless-only floor, and a quality system built around the most regulated sectors in industry, Steel Dynamics UK gives customers greater control over quality, lead times and specification compliance — from enquiry through to delivery on our own fleet.
We look forward to meeting fellow metals professionals at UK Metals Expo. Visit our stand to discuss stock, processing capacity, grade selection or the quality standards behind your next project.
Products & services
Press Braking
Press braking of stainless steel is a highly efficient and versatile method of metal fabrication, capable of producing strong, corrosion-resistant, and aesthetically pleasing parts. Do you need sheet metal folded up to 4 metres in length? No problem! With 3 CNC press brake machines, including the powerhouse Bystronic Xpert Pro 320, boasting up to 320 tonnes of force, we're equipped to handle projects of any complexity.
Plate Sawing
The KastoBloc U5 is a state-of-the-art plate saw designed for cutting large stainless steel sheets and plates with high precision and speed. It's a horizontal band saw that excels in delivering consistent results on thick materials. The KastoBloc U5 is built to handle large stainless steel plates, cutting through substantial thicknesses while maintaining exceptional accuracy. Its robust design and powerful motor ensure that even the toughest materials are cut efficiently. The hydraulic, electronically monitored blade tension and the pivoting operating panel guarantee the necessary accuracy on all straight cuts with a cutting length from 6M to 2M – offering that essential precision with fine and controlled cuts from billets, plates, rectangular or flat material.
Stainless Steel
We only stock premium quality materials from the most leading and reputable European mills. Rest assured, all plate materials are fully certified and come with full traceability reports and mill test certificates, available as standard. Our extensive stock range boasts over 6,000 tonnes of various Stainless Steel grades in thicknesses ranging from 0.5mm – 150mm, and we are confident in supplying and meeting the requirements for a wide array of industries.
Waterjet Cutting
We are home to the UK’s largest 14M x 4M waterjet cutting machine. We can carry out waterjet cutting on Stainless Steel grades up to 200mm in thickness, offering the highest precision and cutting of complex shapes and contours - with minimal tolerances. One of the most significant advantages of waterjet cutting, especially for stainless steel, is that it is a cold cutting process. This means no heat is generated during cutting, which is crucial when working with stainless steel to preserve its mechanical properties and finish. With waterjet cutting, the integrity of the stainless steel remains intact, and there is no risk of thermal distortion.
Fibre Laser Cutting
Fibre laser cutting is a highly advanced method of cutting materials using a focused, high-powered laser beam generated by an optical fibre. In contrast to traditional CO₂ lasers, which rely on a gas-filled resonator to generate the laser beam, fibre lasers utilize solid-state technology where light is amplified through an optical fibre. This technology results in a more efficient and powerful laser with a much higher intensity, which makes it ideal for cutting metals like stainless steel with exceptional precision.
