We love a good supply chain story. Crozier Welding, founded in 1980, started by servicing coal mining operations. Eventually, the company, located in Coshocton County, transitioned from coal to welding pipelines for the oil and gas industry. Today the focus of the company is on welding pressure vessels (holding tanks) for the shale industry. The company is moving and expanding, thanks to an abundance of work coming from the M-U.
