Joists, I have several hundred joists that are approximately 20 feet in length and 16 inches deep. These are red built I90 joists. The flanges on top and bottom are 3.5 inches across. TJI joists are 2.5 inches across. I90’s are stronger. They would work well for floors and even sheds or barn roofs. I am asking $2 a linear foot for these joists. Call or text me. These joists are used but in great shape.
