Shaping the rail industri - One curve at a time

With more than 80 years of experience and a global footprint spanning six countries, Sjolund has earned its reputation as the leading expert in bespoke metal bending for the rail industry. From high-speed trains and metros to infrastructure components, Sjolund supplies precision-bent steel and aluminium profiles that meet the highest demands for safety, quality, and performance.

From the earliest commuter trains to today’s high-speed marvels reaching over 400 km/h, Sjolund has provided the curved metal profiles that give these vehicles their strength, form, and aerodynamic precision. Whether it's curved window frames, door structures, or full-bodied train components, every profile that leaves Sjolund’s production facilities carries the mark of expert craftsmanship, technical precision, and an unyielding commitment to quality.

Rail bending specialists since 1992 

Sjolund began working with the rail sector in 1992, bringing with it decades of metal-bending experience. This deep-rooted expertise, combined with an agile, customer-focused approach, has enabled the company to become a preferred supplier for complex, large-scale rail projects across Europe, Asia, and the Americas.

High-speed trains. Commuter fleets. Light rail vehicles. Locomotives. Stations and infrastructure. Sjolund’s scope of delivery covers it all, and every project benefits from the same high standards of quality, precision, and consistency. Clients, including Siemens, Alstom, Bombardier, CRRC, and Hitachi rely on Sjolund not just for its technical capabilities, but also for its proactive collaboration and smooth project execution.

From Concept to Curved Perfection

What sets Sjolund apart is its ability to support projects from the earliest design phase through to final delivery. Using a tightly integrated project management system, the company collaborates closely with partners across all stages – from feasibility and prototyping to production and logistics.

Each profile is customised to exact specifications, based on material, geometry, and end-use requirements. Whether the challenge lies in high-speed structural safety, tight tolerances, or aesthetic finishes, Sjolund leverages state-of-the-art machinery and highly skilled technicians to get it right. The result? Bespoke, fully compliant metal bending solutions that perform under pressure – even at speeds exceeding 400 km/h.

Certified to Deliver – Worldwide

In the rail sector, safety and reliability are paramount. That’s why Sjolund operates with full transparency and certification across its global operations. With quality systems in place, such as ISO 9001:2015, EN 1090, ISO 14001, OHSAS 18001, and EN 15085 – and active exploration of IRIS certification – the company ensures traceability and performance in every step of the bending process.

Today, Sjolund operates from production and sales facilities in Denmark, Estonia, the UK, the US, China, and the UAE. No matter the project location or complexity, Sjolund’s team is ready to deliver world-class bending services with local support and global reach.

A Proven Track Record

Sjolund’s track record speaks for itself. From iconic European projects like the Velaro and Desiro platforms to metro systems in Venezuela and China, the company’s curved components help move millions of people safely and comfortably every day. The diversity of its project references – from Bombardier’s Aventra platform in the UK to CRRC’s high-speed trains in China – is a testament to its adaptability and engineering excellence.

Looking Ahead

As rail continues to evolve – becoming faster, greener and more connected – Sjolund remains committed to innovation, precision and partnership. Whether supporting next-generation rolling stock or ambitious infrastructure builds, the company continues to bend boundaries for a better, more sustainable transport future.
