Is it that surfaced 4x6 posts, for instance, are Doug Fir? Or are they Hem Fir also, compared to the green 6x posts? I've seen green treated 4x posts, which are not surfaced either, but I was wondering what the difference between the surfaced posts are to the unsurfaced ones.
One thought I had was that surfaced posts are doug fir, and so the treatment doesn't absorb into the post as much as the hem fir posts. But, I don't even know if the posts are different species. So anybody that would know this?

Typically, surfaced posts are 5 1/2" x whatever, or 3 1/2" x whatever. And normally those posts are treated with a red or brown color. Although I have seen green treated 4x posts before. Which led me to think that the actual treatment is different. But then a lumber yard owner told me that Doug Fir is harder than Hem Fir, and so the treatment goes deeper on the unsurfaced posts.

Anyway, I'm just looking for more clarification on all these points. I am confused by the options since I don't understand what they all mean, when compared to the rest of them.

.60 is for in - ground use, .40 is for ground contact and there is also .25 for above ground no contact.
