Sheet Metal Thickness

[NickGTPP]

Hi All -

Does anyone happen to know the body panel sheet metal thickness? I know it’s thin (non-structural, weight savings, etc.). I assume it’s .065 or .070mm?

Any insight would be greatly appreciated.

Cheers

Here’s what IncMe up with using my digital calipers on the passenger side front fender.​

This is super helpful, thank you for the fast response! Looks like .068mm. I think the fender is aluminum. May I ask, if you have time, can you check the rear quarter or roof? Thanks again for the help!!

Rear 1/4 panel directly above the wheel is 0.138, but that’s a rough estimate because the inner lip is rolled. I would guess subtracting 0.020 from that measurement would be closer to what it actually is.

Unfortunately, I can’t see a way to properly measure the roof.

The .068 appears to be in inches instead of millimeters. It's pretty close to 14 gauge. The mm measurement would be approximately 1.75mm. Wouldn't surprise me if it's 1.5mm sheetmetal plus the paint thickness, but that's just a guess.

Thanks again for checking, very much appreciated!

Good catch, I see that now. I assume it’s a higher gauge since the fenders on the S550 are aluminum. I’ve been researching advanced steels and the manufacturing process. Essentially how we are able to make panels thinner due to advancements in steels, elasticity, and body panels no longer being structural on most modern cars. I assume the sheet metal panels on the S550 are thinner, .065, 0.70, .075mm. Somewhere in that range. I know the panels on my S550 are thin but “oil can” (elastic back to original shape) in certain areas if too much pressure is applied. Also found the majority of GM cars are .065mm. However, I can’t seem to find the specific tech data for Ford. Maybe it’s because no one except me actually cares about the stuff.. lol.

.065” not .065 mm.

.065 mm is, for illustration’s sake the thickness of onion skin.

Apologies that was a typo! My mistake. I meant .65, .70, .75mm not .065, etc. .75mm = .029”

Just for a fun reference point, the walls on the Lunar Excursion Module (the ship that landed on the moon) were only 0.012" thick! It was essentially an aluminum balloon.

Just to be clear .068" = 5.597474e-20 parsecs
