These are poplar beams that vary in size, but the most common are 6x6 & 8x8. Most are solid, in good shape and can be used for other projects. These are mortise and tenon beams that are 100+ years old. Strong enough to build with, but soft enough to work with. I also have oak beams for sale. All are a linear ft. Buy more, save more.
