McClymonds Supply & Transit provides dry bulk trucking and supply services to the eastern half of the United States. The fleet includes triaxle (straight truck) dump, tractor-trailer dump, pneumatic bulk tank, roll-off triaxles and trailers, and heavy haul. The Company supplies dry bulk materials to commercial, residential, and highway construction companies, landscapers, industrial manufacturers and mills, and the oil and gas industry, among others.

The trucking operations are headquartered at the main terminal located in Portersville, PA, approximately 40 miles north of Pittsburgh, PA. McClymonds operates a full-service truck garage, body shop, weld shop and three owned and operated wreckers out of the Portersville terminal to maintain its fleet. A central dispatch operation, also located in Portersville, manages all trucking operations.

The Company maintains three aggregate, construction and landscape supply yards in the Pittsburgh region, which provide materials such as limestone, sand, and gravel, salt and mulch at primarily wholesale prices. Materials can be sold as one packaged rate to a job site through furnish and place deliveries.

McClymonds Supply & Transit provides other integrated transportation services, such as third-party logistics.
