Building a shed, workbench, or backyard project? Save big with our off-grade OSB – great for non-structural uses where looks don’t matter, but strength does.
On-grade OSB meets specific performance and quality standards set by industry associations like the APA, making it suitable for structural applications in construction. Off-grade OSB, also known as "reject" or "economy" grade, fails to meet these standards due to imperfections and is sold for non-structural and industrial uses at a lower cost.
✔️ 4x8 sheets of 15/32", 7/16", or 1/2" OSB
✔️ Tough, affordable, and easy to work with
✔️ Ideal for sheds, walls, flooring, and more
DIY-friendly. Budget-approved. Stock up while it lasts!
