I have a proposal from a dock builder that calls for a HDG steel (galvanized) lift. He telles me galvanized will last longer in salt water. Opinions please.
 
If you are talking about a lift dock like you would have behind your house, I disagree with him. I'd go with the aluminum both because of durability and because of weight.

If you ever have to change a cable or pully that question will answer itself. :)

My galvanized lift started to rust a lot after about 5 or 7 years. at 12 it needs to be replaced because it look terrible. It still works fine though.
 
The dock contractor tells me that aluminum due to galvanic action will corrode away, has anyone had that experiance? The lift will be in salt water in Florida behind our house.

Nope. I'm in salt water in Florida as well. Galvanic has not been a problem at all. Lift was built 9 years ago and still looks good as new.

How about Cypress? Wood last longer than either AL or Steel/galvanized.
 
I have a neighbor whose galvanized lift recently broke in half and dropped his boat while other aluminums of the same vintage are still looking and working well. I would think that'd be 'nuff said. I'm in the Gulf.
