Maybe He is making cylinders. He's got part of it almost ready.

He does bring up a really good point here

Cut off a chunk set on 2 4X4 pieces of cribbing at each end convex side up and run it over with a pickup truck. I'll bet it will flatten it out enough to wrestle it into submission

I'm going to have some fun!

I have a few ideas like driving over it while on a bed of sand. But what I really can't wait to try is pulling it through my tractor loader bucket set-up.

I'm going to fasten two 2x4's to the end of a long bord about two feet apart. The 2x4's will be placed under the loader bucket, the other end of the long board will be under the rear tires of the tractor to secure it. I will place the steel sheet on top of the 2x4's and lower the bucket. I will then pull the sheet out with my truck.

I've, worked with plate rolls in a fab shop years ago you are on the right track. But, I believe you are going to find 2x4's are not going to spring the sheet enough in the opposite direction to flatten them out. Try 4x4's you will find that sheet is going to spring back a bunch just my 2 cents

Wow! Just Wow! I don't like to be negative but I don't think you have any idea how much trapped energy and "spring" there is in that coil. I can't imagine being able to get it straight enough to be useful for anything...

Don't buy it. That is my only advise.

1. You don't have the equipment to safely handle it.
2. You don't need to loose life or limb over some steel.

My take on this is he isn't going try to unroll this SOB in one shot (If that is the plan I need some popcorn ) I believe 2 to 8 Ft. sections can be dealt with in somewhat unconventional methods. The biggest variable is how much do you have to spring it in the opposite direction to overcome springback . It will vary with every batch of steel irregardless of designation A36 Etc. and country of origin. Crap steel with lamination's from Asscrackistan is going to behave way different from steel from a quality rolling mill in Canada or Germany. I worked in the Fab shop as a burner,fitter,press brake operator and reluctant plate roll operator. Cheap shit steel was the bane of our assistance.

I think the real question is what are you planning on using this metal for?

My experience with any bent metal is that trying to straighten it requires a steady and continuous bending force applied over its entire length. A series of controller point loads will straighten it to some extent but it will not be properly flat. Think of ‘bump bending’ a curve, you do not get a true curve, but a series of straights joined by a sharp bend.

I don’t think you are going to be able to get this material flat without passing it through rollers, which will need to be quite large diameter and securely supported.

As I said at the start, it all depends on what you are planning on using the steel for.

Good luck.

Rob
