Rosboro manufactures glulam beams and engineered wood products for structural framing, headers, columns, and exposed architectural applications. Builders, contractors, architects, and homeowners can source Rosboro engineered wood products through Golden State Lumber and Showroom for floor systems, roof systems, beams, headers, and structural framing across Northern California.
Rosboro started as a lumber mill over 100 years ago, and since 1963, has remained a leader through innovation. Unlike most traditional glulam manufacturers, Rosboro utilizes an advanced production process that allows us to produce full-width, architectural appearance beams at high volumes and consistent quality. Our unique capabilities enable us to provide the construction industry with the most cost-effective structural framing solutions in the market.
