A common thing on truck chassis is rust, And that's something you do not want! I always wondered why isn't truck chassis Galvanised......It would be something that wont rust and its stronger than aluminum. I think this galvanised truck chassie idea could be something that the gm pickups could use in their next generation along with aluminum exterior. By putting a truck on a galvanised chassis and with aluminum panels this would result in a corrosion resistant truck basically, the only thing would rust would be some components.
Anyone think this could be a good idea to result in a whole better truck for the customers????
If anyone could tell my why isn't this idea taken yet?

Aluminum corrodes though. We traded a Chrysler 300 in on our present car and they would not take it in with the corroded wheels. It was 6 years old and had less than 22k miles on it and the oem wheels were junk. I hunted up a set of nearly new oem take-offs to make the deal.

With as long as galvanizing has been around, I would think the automakers have looked into it, and for one reason or another they rejected it. Dipping an entire frame would be a lot more costly for sure, that's the biggest reason I can see. I personally don't like galvanizing, but I'm looking at it from an restorer's point of view, mainly the extensive galvanization used in the body of the 66 Mustang I restored, and repairing/welding that galvanized steel was not pleasant (which still wasn't rust free might I add).

Galvanized steel weighs a bunch more than aluminum, and fuel economy improvements are looming.

Not sure why it hasn't been used in the past, but I do know welding galvanized steel releases harmful stuff into the air.

You'd think they could just powder coat the frames or do a better job of powder coating the frames.
This. GM need to start powdercoating their frames. Their pickups are already expensive enough to justify this.

Does GM really have a rust problem with their frames? And I'm not talking about a little surface rust.

No more so than Ford or Chrysler. They all rust.

The issue only appears in areas where the protective wax peels or is rubbed off. Its all just surface rust. Its a matter of appearance and people get all worked up about it.
