    Default Weight of Pressure Treated Lumber

    Does anyone know the approximate weight per foot of 8x8 pressure treated SYP piling/timber? I'm guessing around 20lbs/ft but cant seem to find a reference anywhere.

    Southern yellow pine can vary between 31.8 lb/cf to 38 lb/cf. Add in the weight of the treatment and adjust for the true size of the 8x8. That will give you an estimate of the weight.

    For example, if the 8x8 was CCA treated to marine spec, you would add another 2.5 lb/cf to the weight. I think a nominal 8x8 is actually 7.5x7.5. If so, that means you'd adjust the total cubic nominal footage by .84 and then multiply the total actual cubic volume of the 8x8 by the total of the treatment weight and the density.

    Thanks Darren. Is that cubic foot or board foot?

    That is cubic foot but a board foot is also cubic measure but is nominal rather than actual.
