Blanks or boards of proper thickness are split and then run diagonally through a bandsaw to produce 2 tapered shapes from each blank. Avaliable in Premium Grade (100% edge grain) or Number 1 Grade (Up to 20% flat grain allowed in each bundle).

Certi-Sawn® Tapersawn Shakes
These shakes are sawn on both sides. Premium and Number 1 grades are the most common. Premium Grade is 100% edge grain, 100% clear, and 100% heartwood. Number 1 Grade allows up to 20% flat grain in each bundle. Number 2 and 3 grades are also available.
