are you asking me if im going to be using a construction grade lumber?
yes.
are you asking for what specific wood ill be using?
posts will be 4x6 Douglas Fir #1
base and top 4x4 Douglas Fir #1
heavy duty stand.... did that awnser your question?
I would recommend using LVL's and engineered beams not using 4x4's and 4x6.
They are far stronger and straight. Plus DF in 4x4 and 4x6 is going to be expensive, not sure why you would use #1 grade. That is pretty much select grade and wont ever see it... HTH. I know my wood.
