Frame rail gauge
I haven't really measured mine but it "eyeball" looks like 3/16" (0.187). Steel of that thickness is usually not expressed in gauge sizes. FYI 7 gauge is 0.179" thick and is the thickest "sheet metal" gauge I have listings for in my Steel books. I could go measure my frame sometime if you are really interested. The thickness can vary due to metal forming operations also. You can also measure your own frame.

The frame thickness is one of the difference in F100/150/250/350.

Frame rail gauge
hey there....
i used standard 4 inch by 4 inch angle steel. the steel itself was
scrap that was discarded by mason's on a building site. it purpose is
for door headers and such in a masonry constructed building. its about 1/8 thick,,, welded up real nice.
good luck dude

it's amazing... 14ga, comes in about 4 different thicknesses,
must be different mills. but you'd think that they'd keep a tollerence of a few thou.

They all should be in the same neighborhood.
The different alloys, thicknesses, finishes, and processing, make Engineers and Purchasing Agents have nightmares :-(
