100% Transparent Cost Breakdown
We open the books. You pay the factory directly. We charge a fixed fee to ensure your steel structure meets Eurocodes/AISC standards before shipping.
The Hidden Cost of 'Cheap' Sourcing
- Local inspector rejects non-compliant steel
- Material downgrade causes structural failure
- Delayed schedules due to poor factory management
Our transparent engineering fee is not an extra cost—it is an insurance policy against catastrophic project failures.
Don't Trust Promises. Trust the Evidence Chain
What you see before the ship leaves port
We don’t just pass drawings to the factory. Our engineering team reviews your CAD/Revit models to eliminate structural flaws, wind/snow load miscalculations, and ensure strict AISC/Eurocode compatibility before production begins.
Every beam comes with a verifiable Mill Test Certificate (MTC). You receive the exact steel grade you paid for, complete with chemical composition and physical yield strength data—fully compliant with CBAM requirements.
No surprises on your job site. We conduct critical-node pre-assemblies and dimensional tolerance checks in our facility. If it doesn’t fit perfectly here, it doesn’t get shipped.
