I don't have my references with me right now, but they refer to the species of the wood. I believe S-P-F stands for Southern Pine (I'm not sure what the "F" stands for). Different species have different values for the allowable stresses and differing values of "E". If you can get your hands on a copy of the National Design Specification it should clear things up. Also take note of what else is stamped on the wood. The method of grading (visual or machine) as well as moisture content will effect the allowable stresses. So will load duration, the direction of loading, etc. There are far more variables used in wood design than steel. Hope that helps!

I have an idea but cannot find this discussed in the references I have. Thanks.
