    My Dad gave me a heavy galvanized boat trailer with 15 inch wheels. It was used to haul a 19 foot glass ski boat. As you know, the crossbeams are "V" shaped to accomodate the boat's hull. I'd like to cut the crossbeams out and replace them to gain ground clearance and convert to utility trailer. Is galvanized C channel available for the crossbeams and what rod should be used for arc welding? Is this a worthwhile project are just another "money pit" ?

    You can't weld galvanized metal without removing the zinc coating. Just use regular steel channels and weld them in and paint it with a zinc-rich primer followed by a good rustproof paint. Oh, be careful when welding/cutting galvanized, the fumes are nasty.

    Now that I've got your "go ahead," I'll pick up some some steel channel from the salvage yards. Thanks, Kim

    as Grassmechanic said, you have to remove teh zinc coating. i used a grinder last time i welded zinc coated material, the only problem is that when you grind it away it doesn't change colors, so its hard to tell when you're through the zinc, when you start welding you'll know for sure, if its spattering then there is still zinc on it.

    Yes! Be very careful when welding/cutting anything galvanized!!!! The fumes will get into your lungs and crystallize. These fumes are very toxic. I wouldn't weld it unless I had a mask on and was outside.
