Hi. everyone;


Just a short note to all HI's out there that I have received a bulletin from Simpson Strong Tie Company, that explains the corrosive affect on their product since the pressure treatment was changed a few years ago to eliminate the arsenic in the wood. It appears that the new process of pressure treatment, has caused the strong ties connectors to corrode at the rate of two and one half times faster than the projected life of the connectors.
More information can be obtained by viewing the article.

Hope this helps, cause now we have something else to inspect.

Thanks Marcel. This was posyed a while back but is always a good refresher.


CCA vs ACQ

ACQ will make a tapcon turn orange in less than 30 days.

Really nasty chemical, but the EPA wants it.

For newer treated wood installations (likely ACQ treated lumber), look at the fasteners closely … should be stainless steel or heavy coat hot-dip galvanized fasteners.


Here is a more general reference that includes a link to that Technical Bulletin ... http://www.strongtie.com/productuse/corrosion.html?source=hpnav

Here is also a link to the types of fasteners recommended with ACQ lumber for the various fastener manufacturer's ... http://www.treatedwood.com/fastener.pdf

Nice to see that, considering Maine is ten years behind everyone else, that some of you inspectors are on top of it.




Who knows what the future will bring with all these new products!

There have been numerous articles and other general information in the JLC magazine about the problems with the newer pressure treated lumber.

I heard recently,from a local Architect that there is already a new recipe if you would call it, to the pressure treatment formula to address this problem.


Has anyone heard anything about that?


Thanks

I have been all over the web trying to put together a paper on PWF and have not found anything on a new formula. Could you ask the architect for a reference I am very interested?

Larry, as soon as I see the Architect again I will ask him, and what ever I found out, I will respond.


The Architect is the the designer of my bosses house that I am building right now. Construction cost without the 42 acres is about $1.5 to 2 million . I guess now I know who is making the money. ha. ha…

Hi guys


From what I have been able to glean from the web Borate treated wood can only be used above ground and is not to be used in soil contact. So it appears we are back to acq as the alternative to cca. CCA is turning out to be another boondogle on par with asbestos and lead paint. I bet before long we will have cca abatement “specialists” out there charging outragious fees to take the stuff down and dispose of it. Any takers?

Hey Larry, you might be on to something here.

Figure out a way to solve the problem with all the outstanding issues with corrision of existing joist hangers that have been intalled in the past decade, and we might hit it rich.
Now that the problem has been advertized on the table for everyone to see, I would think that someone would have concluded a way to protect previous installations. Dosen't this sound like asbestos?

Maybe this will open up another trade that pays more than HI. business.

Corrosion mitigation Contractor available for your expert resolve on corroding joist hangers. Ha Ha..

This might be considered slander if it weren’t so well documented and proven in court (you really don’t have a leg to stand on Derreck). If you’d like to know how this guy went out of his way to scam senior citizens in Phoenix just visit the links below… or Google him yourself. He was one of two major partners who knowingly marketed illegal investment “opportunities” in Senior World and the Arizona Republic. I can’t understand why any company would hire such a shameless thief as a manager… :shock:
