Can you use 1×6 for deck boards?

Width of material: We recommend only 1×4, 5/4×4 or narrower boards. Never use 1×6 or 5/4×6 material in close to ground applications.

The “nominal” cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions.
