Our story begins in 1890, when Thomas “Whit” Whitaker Rosborough started running his own sawmill. Sixteen years later, Whit Rosborough formed the Caddo River Lumber Company in the aptly-named Rosboro, Arkansas. In 1939, his team migrated to Springfield, Oregon, and opened Rosboro’s first sawmill. Rosboro’s first glulam plant opened in 1963. It was the first in the industry to use several key innovations: ~ Radio frequency beam curing equipment to shorten the processing time, enabling Rosboro to offer glulam as a cost-effective alternative to other floor and roof framing options. ~A continuous pre-glued finger joint allows Rosboro to make long length lamination's. ~ Stress wave machine-graded lumber, which creates stronger and more consistent glulam. Since then, Rosboro has continued its commitment to “Building Better” by using comprehensive information technology services to help create a top-notch customer service experience.
