CCA lumber information.

CCA treated lumber is still manufactured and sold for certain industrial and marine applications, including agricultural posts and poles, and some builders prefer CCA lumber for poles and posts. However, a considerable amount of AC2 lumber is being used, including posts and dimension lumber (2x4, 2x6, etc). You can almost guarantee that any pressure treated lumber that you buy from a lumber yard today is not the CCA lumber that weve all been familiar with for so many years.


I have special ordered CCA lumber from Menards..They don't have any in stock. I called Lowes and they said CCA is outlawed, False news in Indiana.

Some states may ban CCA.
Lawmakers Ban CCA-Treated Lumber. Lawmakers in Maine have approved a ban on the sale of arsenic-treated wood. Despite strong opposition from the lumber industry, Gov.

I have CCA decks built 30 years ago and are still in good shape.
I'm lucky to get 11 years out of AC2 decking lumber.
I've found trapping moisture will shorten the life of AC2 deck boards.
 
Sounds like you could have a field day walking around this place.
They have Pine Fir Cypress and Oak in sizes up to 16 by 16 inches and Pilings up to 70 feet in length.
They offer ACQ CCA and Creosote treated wood.

All that because people ignored advise and instructions and used the CCA lumber for raised beds in their gardens and poisoned themselves. The treated wood they make today is pretty good if it's actually pressure treated. I've purchased Yellawood and when cut you can see the chemical had only soaked in about 1/8' I suspect they just put the wood in open tanks to give it the green color. I use Lifewood brand treated and think it's close to the CCA wood they used to make.
 
Ironic you bring this up after I was looking a large pile today wondering what I should do with it. 2x6 from 6' to 12' and a few 4x4x10. I'm too old and prone to fall climbing on a pile pf lumber. Do you think asking someone to stack it on trailer for half the lumber is reasonable?
The 2x8 floor I put in my open trailer in 81 is still solid and it hasn't spent a day beneathe cover.
 
yup, i learned the hard way. bought 47 6x6x8'treated posts from menards to rebuild fence around barnyard to keep aminals and manure in. i core drilled an 8inch hole in the cement and went in with a 6inch post auger to drill the holes out. then pushed the posts in with loader bucket.ended up breaking one post pushing it in, when looking at it i found that the green treatment only went in about eighth inch. i was suprised. so i took the peice to menards and complained about the treatment was only what looked like a surface treatment. they didnt know, so they sent it in for inspection.they then told me it was good because it was heart wood?
 
Actually all you need is the surface to be treated. The center of a board can go untreated as long as you dont cut the board in smaller pieces than what you bought. If the outside of the board doesnt rot there is no way for the center of the board to rot.

The problem with treated lumber today is the chemical doesnt last very long. It only last for years where as CCA last for decades.

Look at roundup. It kills everything in site. But weeks later new plants are coming up because the chemical to kill them is gone. Same with treated lumber. The chemical wears off and now the fungus can live and eat the wood.
 
George,

Partial truth here, and it is OLD NEWS you have posted about multiple times before.

Maine, [u:e85923bf54]and many other states[/u:e85923bf54], banned use of CCA lumber [u:e85923bf54]for residential uses[/u:e85923bf54] in 2003. That is the same time frame as when the United States EPA banned it for residential use. As a provision in the Maine rule making, Maine lumber yards were allowed to sell, for residential use, CCA lumber they had in stock until April of 2004.

CCA treated lumber was and still is available for some commercial uses. Yes, it may need to be special ordered. Why would a lumber yard stock it unless they were serving an active commercial market that was using/needed CCA to meet a spec?

Yes I have posted this in the past, yet people are still having
issues with trailer decks and want to know how to preserve their
decks. Apparently they haven't read my posts.

So some haven't gotten the message.
Replace decks with CCA, it's available in some states.
If you have problems, go to Menards in a state that allows CCA,



I'm just trying to help those that only read YT when they have
problems..

yes only sapwood absorbs the treatment well--the AWPA specs call for test sample cores to be taken at a certain depth of the sapwood
also the amount of treatment is very important---we always specified cca 1.0 on dimension lumber and 2.5 on pilings in salt water as we have wood borers in the water--any cuts or bruises on the timber had to be coated 3 times with preservative---since it has been banned in NYS ACA is used mostly now
 
They haven't read your past posts, and they're no more likely to read this one.

The original deck boards on trailers don't come CCA pressure treated, and nobody is going to tear the deck off a brand new trailer to put on CCA boards. They will have problems whether you proclaimed the blessings of the almighty CCA treated boards from the highest mountains, or not.
