I’m building a porch that has a large span (24 feet) between posts. The span is so large that a steel I-beam is required. I plan on attaching a pressure-treated 2×6 to the top of the I-beam to provide a nailing surface for the joist hangers.
Here’s my question: The new PT wood is reported to be quite corrosive to steel. Do I need to put a barrier of some kind between the 2×6 nailer and the I-beam? If so, what kind of barrier would you suggest?
Thanks!
Jon

Two layers of ice and water shield.
Apply to the metal beam, and wrap down the sides a bit.

Thanks!

Or he could go with a stainless steel I beam.
Well heck, why stop there ? Why not an epoxy coated titanium i beam ?Or even better yet, gold plate the i beam...;o)The I&W is the standard solution here, and pretty cheap, for such a good solution.

I like that stainless steel idea, but I think you guys missed the obvious solution...... Teak! Actually, teak and stainless would look really sharp together.
Oh, wait, I'm NOT insanely rich. I guess I'll go with the I&WS."Listen, strange women lying in ponds distributing swords is no basis for a system of government."Jon
why are you using pt wood?
interior application where there is no miosture no need for it
It's a combination deck/screen porch, so this beam will see weather. I should have been more clear in my original post.
