Treated wood vs. untreated wood

[billy]

Can anyone provide reliable information as to the strength comparison of treated vs. untreated wood used during cribbing ops.? Provide your sources of information please-no generalities.

Billy,

I have worked in the retail lumber business for ten years.

Most lumber is now CCA treated southern yellow pine. CCA = copper chromated arsenic.
Before that was PENTA = penta-chlora-phenol. Before that was CRESOTE. The spelling may not be exact, but none of this is nice stuff. That is why the bugs and fungus stay away from it.

The species and grade of the lumber is what you want to compare (apple to apples). Treatment makes it wetter and heavier.

Consult <www.hickson.com/specification.html>.
They are one of the biggest players in the treated lumber game. Their site gives a lot of information on standards and specifications about moisture content, weight, grade, & species. It also refers to
other industrial testing standards.

Billy,

I don't know what happened to the site address on the last reply. I'll send it again. www.hickson.com/specification.html (http://www.hickson.com/specification.html)

Yeah, I know it is wood. Is it kiln dried (SPF: spruce, pine, fir), southern yellow pine, douglas fir, treated southern yellow pine that is kiln dried after the treatment process, or a hard wood species? What are the grade, density, and strength ratings?
All kiln dried lumber is not created equal.
