G&L Manufacturing

G&L’s proprietary tubing technology has been well known in the tubing industry since 1982. Our founder, Robert Gilreath, laid the foundation for the company’s success by developing a quality culture and the basis for manufacturing precision tube making equipment, produced right here in Cookeville, Tennessee. The result, tubing produced with outstanding quality and consistency to industry-leading tolerances.

Over the following 37 years G&L has grown from the original 3 mills to 25 mills, expanded our cutting capabilities with production cutting equipment with inline deburr & wash systems and acquired another production facility in Denver, CO to better service our customers. In August 2019, G&L became a part of the O’Neal Industries family of companies. In doing so, we brought together two of the nation’s most respected privately-owned metal product suppliers in order to provide an even higher level of service and greater value than before.
