In the process of deck planning, an issue that is both very frequent and very significant is how thick the deck boards should be. The thickness of the deck boards is one of the main factors of the decks' strength, safety, permanence, and all-around performance. The right thickness is affected by the type of wood, the spacing of the joists, and the way the deck is going to be used.
Though there are still cases when decking planks are 1 inch to 1¼ inches thick, they are predominantly 5/4 decking, and it is the most used option for residential decks. This thickness is compatible with 16 inches on center joist spacing, which is common for many deck designs. Conversel,y if the joists are in 20 or 24 inch wider spacing, then thicker boards with the usual thickness of 1½ inch or more are recommended to avoid sagging and shifting over time.
Wood species is the other determining factor. Strong and hard, dense woods can often cover greater distances than soft and light woods without bending at all. Black Locust Lumber happens to be the one that really shines in this aspect. Black locust is a very tough hardwood with high bending strength; hence, it is the topmost choice for decking applications. Additionally, it is not only the rotting and ants that lead to decay of the wood, but also though it may rot less, it is still lower than the pine board's average life expectancy, and the pine board must be thicker. This is where Black Locust has an advantage. While at the same time coming down to standard thicknesses, it will still be able to offer great longevity.
Increased use of decks, commercial areas, or high-rise structures might all need the stronger support of thick boards, along with the capacity to carry the load that comes with them. Also, heavy-duty boards would be durable, less prone to warping, and still maintain that solid feel portable on top.
At the end of the day, how thick deck boards should be is one question that, if answered correctly, would give rise to safe and long-lasting decking.
