Quality Assurance

Quality Assurance is the essence of producing defect free products. All stages of our work – from estimating and engineering to purchasing, shop planning, production, final assembly, coatings, and shipping – are monitored by our trained personnel and guided by our Quality Management System (QMS).

EDCO’s QC Department is led by an AWS Certified Weld Inspector with over 20 years of experience, and supported by QC Inspectors, NDT Inspectors as well as Final Inspection personnel with decades of “hands on” experience. EDCO’s Quality Management System is independently audited annually to ensure we produce the very best in quality. Routine audits are held by American Institute of Steel Construction (AISC), Washington State Department of Transportation (WSDOT) and the Lockheed Martin Corporation.
