metal thickness

whats the best thickness of metal used for doing a permanent bed cover? like capping off the top of the bed?

i have used 14 guage to do a bed floor, but i think for that i would probably do a 12 guage. I ain't sure about inch thickness of that, but i think i would go with 12...

i was thinking 14, but want to know what everyone else uses. I want it sturdy.

well i went out to the shop and found soem scrap from one i did and i used 12. i ain't got a clue in inches what thickness it is, but it says 12 guage on it.

check mine out I used 16 gauge on my bed and it worked great! hit me up if you have any questions

I would make a support underneath made out of some 1" box tubing and then get your ass come cleko pins and set it in place and weld it solidly with spot welds to the support frame.

It would be best with a frame made from box tubing or angle, with some triangulation. Then you could use a lot thinner material like the rest of the vehicle, like 20 gauge or so. That much 12 or 14 gauge is going to be fairly heavy. The standard thickness for 12 gauge is .109 and 14 gauge is .078

11 gauge is .125 or 1/8"...so 12 would be like 3/32 or 7/64 i guess...pretty heavy shit if you ask me...plan on usin it for a dance floor at shows or what?...i'd use some 16 gauge and frame the top of the bed rails in 1" square tube then weld the shett to the framing

i used 1" round stock 1/4 inch wall thickness with 10 gauge sheet steal for my floor and walls. but im way overboard and im always hauling sum bike or wheeler. need it sturdy.

thats savage.
if i was cappin a bed i'd probably build a frame across the rails to set it on, and then go with some 16ga or 18ga
