- AISC Certified Simple Bridges
- WBE Certified
At Di Highway Sign & Structure, every fabricated product is thoroughly inspected for quality, prior to being shipped. We employ four AWS Certified Welding Inspectors in our QC Department. In addition to weld inspection, they are involved in management of the Quality System from project planning through certification. Our Quality Control Policy is to ensure that all fabricated products comply with the quality requirements, as prescribed by the customer through plans and specifications; and also to standards and quality control procedures as required by Di Highway, and International, Federal, State, and Local agencies. Di Highway is currently certified by the AISC for meeting the quality system requirements of "Certified Bridge Fabrication Simple." When QA (third-party) inspection is required by a specific contract, Di Highway will bring in a State inspector or a representative from an outside inspection agency to work with our Quality Control Department.
