About Rubb, Inc.
Rubb, Inc., doing business as Rubb Building Systems, is a self-certified small disadvantaged business and for-profit manufacturer of goods headquartered in Sanford, Maine. The company specializes in fabric-covered, tension membrane structures and buildings designed for military, defense, and industrial applications. Since its registration in the System for Award Management in 2002, Rubb has established itself as a trusted federal contractor and grant recipient, primarily serving the Department of Defense and related agencies through the provision of specialized building systems, temporary shelter solutions, and maintenance services.
Through prime federal contract awards, Rubb has delivered a diverse portfolio of goods and services valued at over $1 million across multiple defense agencies. The company has manufactured and installed storage buildings, aircraft shelters, and munitions storage facilities for the U.S. Air Force, Air Forces Europe and Africa, and the Air National Guard, with notable projects including a $144,615 munitions storage building at Buchel Air Base in Germany and a $176,125 building upgrade for the Air Force completed in January 2026. Rubb has supplied propeller tents and related fabric structures to Naval Sea Systems Command under two substantial purchase orders totaling over $221,000, and has performed repair and maintenance services on Navy tents valued at $79,905. The company has also provided inspection services for fabric-covered tension membrane structures to the Air National Guard, including aircraft shelter inspections and bi-annual facility inspections under contracts ranging from approximately $5,600 to $18,200. Additional work includes cinch strap and pocket tube replacements and roof repair services, with one Navy roof repair contract designated as a Total Small Business set-aside. Rubb has also served as a subcontractor to major defense prime contractors including Lockheed Martin Corporation, Fluor Idaho LLC, and Battelle Memorial Institute, providing fabric structures, maintenance shops, and materials to support Department of Defense and National Reconaissance Force activities. The majority of these contracts were awarded without set-aside designations, reflecting the specialized nature of Rubb's capabilities.
Through federal grant awards, Rubb has received a $128,500 Project Grant from the United States Department of Agriculture's Rural Business Cooperative Services under the Rural Energy for America Program, awarded in April 2025 with a completion date of April 2027. This grant supports Rubb's development of renewable energy systems, representing a strategic expansion of the company's business capabilities beyond its traditional defense sector focus into sustainable energy infrastructure. The grant demonstrates federal recognition of Rubb's potential to contribute to rural economic development and clean energy initiatives while leveraging its manufacturing and construction expertise.
