what lumber should be used on a flatbed

I'm obligated to remind you that your state is right next door to the
world nut capitol... Kalifornia.

I agree with everything in your post with the exception of this statement.

Arkansas isn't really close enough to be considered "right next door" to Kalifornia.

Mistaking AR for AZ isn't nutty but nuts do grow everywhere.

Just because your state outlawed it doesn't mean it's illegal everywhere else.

I'm In Pennsylvania and I can still buy old fashioned (and effective) CCA treated lumber.

I'm not sure how available it is elsewhere, but it would be wise to check

I'm in Arkansas, and its an EPA thing. CCA-treated lumber has been banned from all residential use (In the whole US) since 2003. I thought it was a ban on all use, thats my mistake. A total ban is probably not far off.

Building codes from using it in home building aside

I just bought several CCA treated 6x6 timbers
as "sleepers" to bolt the steel frame for a pallet rack to.

It's possible that the stuff I bought was "old stock",


CCA Chromated Copper Arsenate
On 1 January 2004 the Environmental Protection Agency (EPA) in a voluntary agreement with industry began restricting the use of CCA in treated timber in residential and commercial construction, with the exception of shakes and shingles, permanent wood foundations, and certain commercial applications.

in CCA the Copper is a fungicide, the Arsenic an insecticide and the chromium is
a fixative to make it less water soluble.

The newer stuff isn't as effective and if you need to bolt it or screw it together
you need to use heavily galvanized or stainless steel fasteners becuse the new
stuff is more corrosive.

Personally I'd rather use Locust, I just wouldn't want to cut down any of my locust trees

If you look at all the old flat bed trlrs they used 1 1/2 inch white oak. Has strength and longevity. Up here in Mn. you still see a lot of trlrs still using it.
Just my .02 cents worth
