Our Story
Glenn and Linda Rexroth started small...very small. Linda took calls and dispatched their one concrete truck which Glenn drove for concrete deliveries.
Thirty-nine years later…Glenn and Linda's son, "JR" is now part of the management team, taking the company into its second generation of this hardworking family.
For many years Bruno, the family's beloved dog was the company mascot...coming to work with Glenn and Linda every day. While Bruno can never truly be replaced, a new dog, named Axle, helps Glenn, Linda, JR and the entire Tri-Boro Construction Supply team run the business now, from his distinguished place under the conference table.
The main plant, showroom and office complex is in Dallastown, PA, which spans several acres in southern York County, PA. The facility is prepared to deliver sand, stone and a vast assortment of building and safety supplies from its 100,000 sq. ft. warehouse over a wide area of Pennsylvania and Maryland. We also ship many items all over the world.
Our other showroom is in the northern PA, town of Carlisle, PA, and houses thousands of concrete tools, support equipment and safety merchandise. The 48,000 sq. ft. facility fabricates rebar for the entire Tri-Boro Supplies company and is prepared for immediate delivery to Pennsylvania's northern counties.
Tri-Boro Construction Supply is your single source stocking distributor.
Tri-Boro Construction Supply constantly trains personnel and upgrades equipment to assure that you receive the benefit of the latest technological advances in the industry.
