At Matco, we specialize in conducting corrosion testing and failure analysis investigations. This requires not only a laboratory that features state of the art equipment, but an extensively trained multidisciplinary professional staff as well. The Corrosion Testing and Product Development Laboratory, located in Pittsburgh , Pennsylvania , has been in existence since 1993 and is one of the premier corrosion testing and inspection facilities in the Northeast.

Our recent field investigations have included major codenser failures in West Virginia, failure of paint/galvanizing coatings on galvanized structural members of a large stadium in Hawaii, analysis of failures of salt-water plumbing on a luxury yacht in Antigua, failures of cathodic protection systems in a submarine tunnel in Chesapeake Bay, failures of polyurea roofing systems in a university in south Florida, corrosion of lead-coated copper roofing in a government building in Illinois, and analysis of the incipient failure of concrete in the dome of the State Capitol building in Salt Lake City, Utah.

The investigation of corrosion failures can be very complex, and usually requires multidisciplinary testing and analysis to determine the root cause of failure. The end determination must be able to be made with a high degree of certainty to ensure that proper replacement materials are selected and that the most effective corrosion control methods are used. Experience is surely the most important ingredient to look for when choosing a materials firm to handle your corrosion control and failure analysis needs.
