Which decking material is most prone to moisture retention?

Metal deck
Concrete deck
Wood plank deck
OSB deck

The correct answer is: OSB deck

OSB (Oriented Strand Board) is a type of decking material that is most prone to moisture retention when compared to the other options listed. This is because OSB is more porous than other decking materials like metal, concrete, or wood plank. Due to its composition of wood flakes and resin, OSB absorbs and retains moisture easily, which can lead to deterioration and compromise its structural integrity over time. It is important to take adequate measures to protect OSB decks from moisture exposure to ensure their longevity and performance.
