Heavy Steel StructuresThat Require PrecisionCertified to EXC4 standards
Custom welded and machined steel components up to 12 m and 25 tonnes, with 0.05 mm precision over 10 m. Certified to EN 1090-2 EXC4. Trusted by Airbus, Bosch Rexroth, and Continental.
Trusted by global leaders in aerospace, rail, and heavy industry.
The Challenge: Heavy Structures That Demand Precision
Engineering teams struggle to find manufacturing partners who can deliver both large-scale capacity and extreme precision in a single, integrated process.
Most suppliers either handle large structures but can’t achieve tight tolerances, or offer precision machining but can’t handle heavy components. The result? Managing 4-5 different suppliers, coordination nightmares, schedule delays, and finger-pointing when problems occur.
For critical aerospace, railway, and industrial projects, there’s no room for error.
