What sizes of lumber are typically treated and approved for ground contact?
Breaking Down the Lumber Label
0.60 is the lumber’s retention rate, or the amount of preservative used to treat the wood. The higher the retention rate, the lower the biodeterioration rate. UC4B is the Use Category. UC4B lumber is suitable for ground contact and contact with freshwater.
Which is better #1 or #2 pressure-treated lumber?
Typically wood that is two or more inches thick is graded only for strength, denoted by #1, #2 and so on. And because stronger lumber has fewer and smaller knots, it’s typically more attractive. So the general rule of thumb for lumber grades is this: the lower the number, the more strength and better appearance.
