Our Process
Successful fabrication projects rely on careful planning, qualified procedures, and rigorous quality controls. From RFQ through final delivery our process is designed to ensure consistency, traceability, and confidence throughout production.
01
During the RFQ stage, we review welding specifications, fabrication complexity, quality requirements, and potential challenges to identify the best path forward.
02
Fabrication strategies, welding procedures, certifications, and production requirements are established. For complex projects, cross-functional pre-job briefings align teams before production begins.
03
Routers guide every step of production—from material prep and fit-up to welding, cleaning, machining, testing, and finishing—ensuring consistency and traceability throughout fabrication.
04
Testing, inspections, documentation, packaging, and final verification are completed before shipment to ensure quality, compliance, and customer confidence.
Fabricated. Qualified. Delivered.
