Thread: What thickess sheet metal

Tweet

What thickness or gauge sheet metal do you all use on vehicles where you have to cut out places and weld in new metal that are rusted out

Do different places on a vehicle require different gauges ?

has abit to do with car or truck box or not most of the time car frames are not very thick i use .125. cross overs are abit thicker some times

Patches should be the same gauge as the parent metal, whatever that is.

yep same gauge most GM frames and others are less then 125 . so .i go a hair thicker if i am welding and dressing / blending so 1/8to 3/16 is fine if your working it some

Door panel patch is 1/8 sheet metal.

? what on a tank ?? most of the time i use 18 gauge . gm frames are not much thicker then .090 from 60s up to 80s

I use 20 ga. for sheet metal repairs, and as Pat said usually 1/8" or 10 ga. on frames.

Did you maybe mean "18" instead of "1/8"? Like R Pope said, you generally make the patch as close to the parent metal as you can, within a gauge size or two.

where or why i was thinking it said frame repair first post ??? .it.s not here
any were? but any ways on frames that about right on body sheet metal i started using 18 gauge abit thicker but on older cars it works for me better as i like to work the metal out close as i can

Well, Pat, Studebaker frames were made out of steel not much thicker than a fender! They had a tendency to rust right away, I helped a buddy swap the frame on a Shovelnose back in the '60's.

Hi Guys, I am new to this forum, but not to sheetmetal work, I own a metal repair shop I call The Old Tinman, I specialize in body repairs. For english wheel work and patch panels 18 gauge seems to be all I use these days. It seems to work on almost every application for cars 1960 and older. 20 gauge on the newer stuff.

yep you guys in cal do tin work... you call it custom work .... us guys that been at it in the rust belt it called rust repair on a cold winter night here in michigan you can hear the rust eatting the lowers off your car parked out side. sounds like granddad eatting a tin ear of corn
