FLORENCE — Florence-based Martin Supply is ranked No. 44 on Industrial Distribution magazine’s annual Big 50 List of North American Industrial Distributors.

This is Martin Supply’s fourth year in a row to make the Big 50 list.

Martin Supply, a subsidiary of Martin Inc. in Florence, provides custom-tailored solutions for maintenance, repair, operation and production supplies for industrial and construction customers.

The Big 50 is determined by a distributor’s most recent full-year, worldwide sales numbers generated by their North American operations.

Martin Supply reported 2021 annual sales of $156 million, an increase from the previous year due to two significant acquisitions that boosted their bottom line.

Martin Supply acquired Parker Industrial Safety of Avilla, Ind., in May 2021; and Martin Fastening Solutions, also a subsidiary of Martin Inc., acquired Capital Bolt & Screw headquartered in Jackson, Miss., in September 2021.

A printed version of Industrial Distribution will feature the Big 50 in the September/October 2022 edition.
