U.S. LUMBER, one of the largest, privately held distributors of specialty building materials, can proudly point to the millwork segment as a cornerstone of our business. Founded in 1988 by Lawrence Newton, we have expanded beyond our Birmingham, Alabama roots to serve our customers across North America and Canada. Over time, we have consistently enhanced our product and service offerings while remaining committed to maintaining the highest standard of trust with our customers and suppliers. Both U.S. LUMBER and Alexandria Moulding are positioned to effectively address every need in the market for moulding products.
U.S. LUMBER is a “values” based organization, governed by a culture of respect, honoring people first, and operating according to a true moral compass aimed at doing what is right. U.S. LUMBER diligently extends that circle to each of our employees, our customers, our suppliers and everyone that we encounter in the business.
Specialty Building Products (SBP) operates through six brands in the United States and Canada, including U.S. LUMBER. Individually, each brand has a rich history of its own and is well-known within the local community it serves. Together, as one company, we are better prepared to meet the growing demands of the building industry with an unmatched depth and breadth of inventory, in-person support, and robust selling systems. When you see “an SBP brand”, you can expect the same personalized experience you know and trust, with the strong commitment and support of the fastest-growing building materials supplier in North America.
