Steel Stockholders & Steel Suppliers

Steel Stockholders & Steel Plate Suppliers

For over 75 years, SM Thompson has been a trusted steel stockholder and steel plate supplier, serving customers across Middlesbrough, the North East and throughout the UK. We stock a wide range of high-quality steel plate and combine our extensive inventory with advanced in-house processing, providing a complete solution from raw material to finished component.

Unlike many steel suppliers, we don't just supply steel—we process it. Our in-house capabilities include laser cutting, plasma cutting, flame cutting, plate rolling, section rolling, press braking, drilling, tapping and chamfering, helping customers reduce lead times, simplify their supply chain and receive steel ready for fabrication or assembly.

Whether you require a single plate, a bespoke profile or a full production run, our experienced team is committed to delivering quality, reliability and exceptional customer service.
