The prefinished STB 15 is part of the Superior Sandblasted Faux Wood Beam Line. Superior Building Supplies sandblasted beams have a beautifully elegant raised grain running throughout the beam. The Superior Sandblasted faux wood beams are molded from a carefully sculpted real wood beam. Because each beam is molded from real wood, there are no repeat patterns within it. 1000's of customers can't be wrong, Superior faux beams are a beautiful addition to any project. The STB 15 is 6 in. wide x 6 in. high x 19 ft. 3/8 in. long. These beams are light weight and can easily be installed with just 2 people. Every STB 15 faux wood beam is hand finished with an interior grade, multi-tone rich walnut stain. Our Superior Faux beams can be used outdoors. We recommend purchasing unfinished beams and painting or staining them in an exterior grade product. Don't see the size you want? Contact Home Depot today.
