Ohio Material Inspections

McCreath Laboratories has a long history of servicing the industry in Ohio.  At one time McCreath had locations in Cleveland and Youngstown, OH.  Today, the main office is outside Youngstown with satellite locations in Toledo and Sandusky, OH.   The staff working out of the Youngstown office are equipped to travel anywhere McCreath does not have an office.  They cover from Quebec City, Canada to Decatur, AL and everywhere in between.  With mobile crushing capability, the staff will take from the site only what is necessary to send to the lab for analysis.  The main services provided by this office are:

Our other two locations are very specialized.  We are on-site at Sandusky Coal Dock on behalf of our partner, Sampling Associates International, providing sampling services to customers shipping through the dock.

Our Toledo location specializes in petroleum coke but can provide services for other commodities as well.  The staff works closely with Midwest Terminal, Toledo, to sample inbound and outbound petroleum coke for our customers.  The Toledo staff provides sampling and screen tests on a routine basis and can also provide pile survey services.
