Quality Assurance

No two projects are alike. For this reason, MarShield designs a quality system that matches the specific procedure required to produce a quality nuclear lead pour. MarShield works together with our clients to ensure a system of quality controls that meets theirs, or their client’s specified requirements.

MarShield creates various documents to ensure that all steps of the pouring procedure are followed. This ensures that the sub-elements of the job meet the necessary requirements in order to produce an acceptable part. Our quality assurance staff analyzes all of the documentation for variances and, when necessary may implement corrective procedures during the manufacturing stages to guarantee all requirements have been met.

Our quality management system is certified to both ISO 9001:2008 and CAN3 – Z299.2:85.
