What you see before the ship leaves port
BoltSprout engineering team auditing Revit/CAD models for structural flaws and AISC code alignment.

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.
