Pressure-Treated Wood For Bunks and Aluminum Boat

[aaarneson]

I just bought some Pressure Treated 2x4's this morning for replacing my bunks on my trailer. I then started reading on the internet that I could face some corrosion problems. If I carpet the 2x4's will this still cause corrosion problems? What if I resin coat them? Or should I just go buy regular 2x4's?

Thanks

I doubt it will be a problem-is the boat painted?
if carpeted, no problem.
Or paint the bunks.
The pressure treated chemical won't be an issue anyway once it dries.

No....The boat is not painted.

The PT lumber industry advises against using aluminum in contact with any variety of PT lumber.

Carpet will not stop the leaching of the chemicals out of the lumber every time you dunk your boat. Unless your confident that the moisture barrier of rubber or plastic backing of the carpet will not develope a leak.

You could get a vinyl siding contractor to make you some vinyl trim shaped like a channel to fit over the bunk wood. Then carpet over that.

What is you trailer made of? Now there are more metals for the new stuff to corrode. Although if it is galvanized it would be okay, supposedly.

Take the PT wood back. The copper used to treat the wood will leach thru the carpet. I have a 1436 jon boat and used cedar for the bunks. Plain 2x4's and thompson water sealer will work well.

I was able to take it back....I just got regular 2x4's cut to length I need and I am going to resin coat them since that is what I have. Then I will wrap in carpet.

Thanks everyone for the help.

I wouldn't resin coat the bunks that may trap water in the wood. There only 2x4s they won't last for ever but they don't cost much.

I have never heard that before....Many people resin coat there plywood they put in there boats with great success...Why would this be any different? Not trying to be smart....Just curious. Also, I am not worried about the cost...more concerned about having to do this more often than I have to.

Having just rebunked my trailer, I recommend going with SS carriage bolts vs. the lag screws that it came with. The screws were constantly working loose and eventually chewed up the wood, hence the rebunking.

It took a little more time to rebuild the bunks with the carriage bolts (I put them through the bunks, carpeted over them, then bolted to the brackets) but the bunks are much stronger and the nylock nuts won't be working loose all the time.

With any wood that you coat with resin if there is any water intrusion the wood will have a hard time drying out. For bunks I myself wouldn't worry too much them. Although I used cedar so they should last longer than standard 2x4's.
If cost is not an issue try to find cypress that will last a very long time
