3/4" A36, low carbon, hot rolled plate should be approx. 30.6 lbs per square foot.

Edit: That is straight from Ryerson's stock book.

 

I'll call again.
Thanks!

I called and the guy talked me out of it; he said way cheaper to just get scrap plate.

 

Can tarp the box and fill it with water??

 

It won't stay frozen though; I already thought of that. Concrete in a wood frame would work, but then how do you get it out after? Forklift would be the only way.

 

yea go with the 2 500# chicks can take em out easier when you dont need them

 

They sell an air bladder that you fill with water. The water freezes and I think it weighs about 500 pounds or so.

Pretty sure Cabelas has them.

 

I used to use a chunk of concrete made to fit between the wheel wells on my 79 Silverado. Left the frame on it that sat over the wheel wells so that it would not slide. I made it so I could pick it up with a cherry picker. Worked like a charm, I wanna say it weighed close to 600ish pounds.

 

How about one of those water sacs they sell on some sites? Hell go cheap and use a water bed bladder. 7lbs a gallon you could probaly get away with a twin size.

 

hey you can always get you some larg long sand bags fill with mixed sand dirt and pet graval thats what i use the long bags if you pak them tight you can get them to wiegh like 100#s just get you a couple there safe and pretty easy to move

 

That plate would weigh around 120lbs, not sure how they got the 10lbs! A 4'x8' sheet of 3/4" is just under 1000lbs.
