Set your next project up for success with construction and building supplies from Tri-Boro Construction Supplies. From abrasives to windows, we carry a wide range of products inside our large warehouse. Company founders, Glenn and Linda Rexroth, started small-very small. Linda took care of all the calls, while Glenn drove for concrete deliveries. 41 years later, Glenn and Linda's son is part of the management team, taking this hardworking family company into its second generation. Our main plant, showroom, and office complex are in Dallastown, Pennsylvania, spanning several acres in southern York County. From its 100,000 sq. ft. warehouse, the facility is prepared to deliver sand, stone, and a vast assortment of building and safety supplies over a widespread area of Pennsylvania and Maryland. Many items are also shipped worldwide. Another showroom is in the northern Pennsylvania town of Carlisle and holds thousands of concrete tools, support equipment, and safety merchandise. This 48,000 sq. ft. facility fabricates rebar for the entire company and is prepared for immediate delivery to Pennsylvania's northern counties. For many years, Bruno, the family's beloved dog, was the company mascot and came to work with Glenn and Linda every day. While Bruno can never truly be replaced, a new dog, Lola, helps Glenn, Linda, JR, and the entire Tri-Boro Construction Supplies team run the business from her distinguished place under the conference table.
