GWW vs URI Comparison

Founded in 1927, W.W. Grainger originally distributed various motors via a mail-order catalogue. Over the course of the 20th century, the firm expanded into new industrial product categories and launched its first digital catalogue in 1995. Today, the company organizes itself into two segments focused on different customer bases. Its larger segment, high-touch solutions, offers a vast array of maintenance, repair, and operations, or MRO, supplies and bespoke inventory management services to larger businesses. Its smaller segment, endless assortment, operates two online platforms, Zoro and MonotaRO, that offer comprehensive catalogues of MRO supplies to smaller businesses. Grainger has operations throughout the world but primarily generates sales within the US.

United Rentals is the world's largest equipment rental company. It principally operates in the United States and Canada, where it commands approximately 15% share in a highly fragmented market. It serves three end markets: general industrial, commercial construction, and residential construction. Like its peers, United Rentals historically has provided its customers with equipment that was intermittently used, such as aerial equipment and portable generators. As the company has grown organically and through hundreds of acquisitions since it went public in 1997, its catalog (fleet size of $21 billion) now includes a range of specialty equipment and other items that can be rented for indefinite periods. 2024 revenue totaled $15.3 billion.
