A business idea that began in a small, rented section in the back of a manufacturing facility has grown into a full-service machining and fabrication corporation, dedicated to prompt, courteous, and quality service. We currently inhabit a 15,000 square-foot facility. We service industries, such as railroad (commuter and freight), power, power transmission, roofing, food service equipment, agriculture, textile, electronics, forestry products, construction, facility repair and maintenance, healthcare, marine, and security.


Gainey Machine & Fab., LLC, is currently owned and operated by Donna and Michael Gainey, the son and daughter-in-law of the founders, Joseph and Joan Gainey.


Joseph started Gainey Tool and Machine Co. back in 1967 in Marietta, Georgia. In 1973, the business was relocated to Hartsville, South Carolina where it remains today. In 2005, his son, Michael, and daughter-in-law, Donna, purchased the business, incorporated and changed the name to Gainey Machine & Fab., LLC.


Michael has been employed here since 1984, with a brief leave of absence to attend Spartanburg Technical College and Florence-Darlington Technical College. His knowledge and experience, gained from years of hands-on training, have proven to be a tremendous asset to our company and our customers.


In 1993, Donna joined the company and has developed and put into place our tracking and quality control systems in order to better service our customers and ensure on-time quality products. Today, Donna is responsible for material acquisition, process control, personnel and all accounting services.


We have achieved our success by expounding on our greatest commodity – “Quality Service”.
