Established in 1996, Keystone Building Products has been supplying materials to the manufactured and modular housing industries for nearly three decades. With locations in Selinsgrove, Pennsylvania, and Salisbury, North Carolina, the company serves a broad region east of the Mississippi River, including areas as far west as Indiana and as far south as Georgia and Tennessee.
Keystone offers a range of products tailored to factory-built housing, including siding, doors, windows, shingles, kitchen cabinetry, aluminum products, and various accessory items. Approximately 99% of the company's sales are directed toward the manufactured housing sector.
In recent developments, Keystone introduced a new product line—High Rock Doors, a proprietary exterior door unit. Currently in its early stages, this line is gradually expanding as the company refines the product and scales its operations.
While acknowledging challenges such as increasing tariffs and material costs, Keystone continues to focus on service and product reliability. The company emphasizes the importance of net cost over acquisition cost, aiming to provide consistent support and dependable inventory management to its customers.
