Spacing is also important to consider. If you wet boards with a moisture content above 19%, little to no spacing is needed, as the boards will shrink as they dry. However, if you dried your boards or are using KDAT, leave 3/16 in. spacing between boards to allow for expansion and contraction.
The wood itself won't expand in length when it gets wet or hot but it will swell slightly in thickness and width when the truck floor is exposed to moisture. A 1/8" gap edge to edge between deck boards is generally recommended for center frame and outside frame trailers.
Having a decent gap is good for the longevity of a deck as too small of a gap allows debris to get trapped in between the boards, the debris will trap moisture longer leading to rot.
You MUST treat the ends and any cuts with 3-4 coats of preservative AND be sure there's a gap between the boards ! ANY 'standing ' water will eventually rot a board. 3rd. clean the trailer top and bottom !,keep deck tilted,in the sun and wind. If it's dirty and under trees, moisture invites mold and bugs and rot...
It is always wise to use pressure treated boards when flooring a trailer. Any material that you would brush on the surface would not penetrate very far into the wood. Might help some if you would surface treat it two or three times each year.
Without gaps, this movement can cause the boards to warp, bend, or even crack. The gaps give the boards enough room to move without causing damage. Moreover, gaps help with drainage. Water can pool on the surface of the deck if there are no gaps, leading to slips and potential water damage over time.
The recommended gap between decking boards typically ranges from 1/8 inch to 1/4 inch (about 3 to 6 mm). This gap allows for proper drainage and airflow, which helps prevent moisture buildup and promotes longevity.
Plywood floors are stiffer than OSB floors by a factor of approximately 10%. As a result, OSB floors are more likely to: squeak due to floor movement; cause hard floor surfaces to crack (such as tile); and.
TREATED LUMBER FLOORING Pressure treated Pine flooring is the most commonly used wood flooring material in trailers. The abundant supply of Pine wood in the south coupled with its sturdy nature make for a solid basic flooring choice.
The more structure and support you have on the bottom, the thinner you can go. 0.045″ would be the thinnest we recommend. If you don't have a strong support on the bottom or you have beams, then you should go thicker. The most popular thicknesses would be 0.188″ (3/16″) or 0.125″ (1/8″), and even 0.25 (1/4″).
