Aluminum over treated wood problem


Two years ago we had a porch built. The post were built of treated lumber and wrapped in aluminum. Of coarse the post have now pitted and
and holes have appeared. The contrator has removed the aluminum and painted the post and plans on replacing the aluminum within the next day or so. My question is, there is already staining bleeding through the
new paint. Will this cause a problem with the new aluminum? If so , how should it be approached? Thanks.

Why in the world would he put more alumium back on!
Read the box of coil stock in big letters it says not to install on pressure treated wood.
Just painting it will do nothing to protect it. It's still going to corrode where the nails go in.
They make a bunch of differant wrap around post covers out of PVC and fiberglass that should have been used.

Aluminum over treated wood problem


Part of the problem is me. I wanted, and still do, 6 or 8 inch square post, that I would not have to paint. I questioned the aluminum over treated wood when it was first installed and was told that I would not have a problem. I had researched and thought I knew what I was talking about, but erred and listened to my contractor. When you speak of wraps, are they the thin paper/plastic type wrap they use to cover outer walls on new construction or is there a certain product that wraps that I should be researching? Thanks

I guess I have to wonder why they put sheet metal over treated lumber in the first place...

I don't know. I checked out the comapny and it had a reputable reputation. Just got off the phone with head honcho and he said he would talk to his installer and see what he thought. Said they had never, ever had this problem.

If he's never seen it then he has not been in business long.
I see it all the time around gargage doors.

Looking into the post wraps that Joe suggested. Now finding the wrap in a color other than white or tan is an issue. I do not want to have to paint the post and since it just a few posts, it would be rather expensive to have them special made in a cream. Going to the box stores today and see what they can do.

Aluminum over treated wood problem


what you have is a case of dissimilar metals. preservative treated wood typically has copper. by nature you'll have a galvanic reaction which will cause the metal to deteriorate.

go with something like pvc or vinyl. there are many wrap options available.

good luck!
