Skateboard Decks are made by joining numerous plies of wood and fibers together using an industrial press. This process is necessary to ensure the glue or epoxy bonds effectively with the wood and fibers, resulting in a strong, durable skateboard deck. Mass production skateboard decks are often pressed up to twenty decks at a time, whereas premium and pro series decks are all individually pressed. Individually pressed decks are superior, stronger, and more durable. They are also more consistent and more reliable.
