1” Grooved Edge Board - available in 8' *, 12', 16' and 20' lengths.
1” Square Edge Board - available in 8' *, 16' and 20' length.
Square edge boards are designed for surface fastening. Use for stair treads and picture framing.
* Please Note: The 8' boards are a Shipping-Optimized Version, designed for safe loading and unloading from tailgate delivery trucks — ideal for long-distance deliveries beyond DeckMart’s local delivery radius. This option offers a significantly more cost-effective alternative to flatbed truck deliveries. Boards are sold in pairs only.
Important: Once an order for 8' boards is processed, it cannot be returned, and payments are non-refundable, as the boards undergo a cutting process and are no longer in their original manufacturer's condition.
Fascia Boards are available in 12' lengths.
Riser boards create the back portion of stairs. They are installed at a 90° angle to the stair itself.
Fascia boards are trim boards used to finish the sides of a deck.
