Engineering T-GRADE OSB Flooring began with our most valued advisor. You.

After talking with our builders, distributors and partners, Tolko invested time and resources into engineering its OSB APA Rated Sturd-I-Floor. We've upgraded our manufacturing processes and invested in technologies to improve the quality of all our panel products. The result: T-GRADE OSB.

Moisture resistant and edge sealed with Tolko’s recognizable blue proprietary edge seal, T-GRADE resists warping and stays true longer. T-GRADE panels are skip-sanded to provide a tight tongue-and-groove fit, and a smooth floor surface between panels.
