Default 3,400 lbs. Coil Sheet Steel

I am planning to buy this coil next week and am a bit concerned about releasing the energy when it comes time to cut off a piece.

The the coil is about four feet wide and the thickness looks to be a bit under 1/8". It is currently held with about five steel bands. As mentioned it weighs 3,400 lbs. I estimate the sheet is about 180 feet long.

I have a few ideas how to handle this but I have never worked with coiled sheet before, I don't know exactly what to expect. How would you fellows handle this?

popcorn and a front row seat in the bleachers

A come a long around the middle then start cutting straps in a controlled pattern from outside towards the center.
As you cut the straps you should be able to judge how much strain is on them and treat the trap as safely as possible.

MAybe 2 pieces of all thread, and 2 bars (one on the inside bore of the roll)
and one outside.

apply this clamp, and then cut the banding.

Slowly undoo the all thread to open up the gap between the clamp bars.

Start to pull out what material you need, shoving the clamp back into the
unrolled material.

You almost have it there! Your idea is missing another set of clamps!

With two clamps as you describe one could be left tight while the other is removed. They could alternate positions until the desired amount is removed. With this method there will always be one clamp in place. I like it!

My idea was to make a few stitch welds across the edges of the rolls, perhaps four or five on each side. I would then use a cut-off wheel to cut a layer of sheet on each side as needed.

Yes, I like your idea of 2 clamps, and then don't do the tack welding.

I think it would be safer in the back row!

I like Doug's idea of a "clamp" that you loosen and slide to expose just enough metal to cut. Would also keep it from rolling away

How about two chains and binders or get inside before cutting the bands

I just used a come-a-long and nylon lift strap on mine...
once the metal straps were cut and I slowly released the tension a click at a time it didn't spring out very much...

problem was after the tension was released it was a total PITA to roll off the sheet by my self due to the weight of the roll
I had built a rack with a pipe that went through the center to use it to roll the spool but didn't help was just too much weight so I flip a little off at a time and have to pull it back through to get the lengths I needed

my spool is 20 ga. galvalume and very springy when rolled in the spool...
the spool was 40 inches wide and a little over a 20 inches thick in coil now I'm down to half that and still can not spin it with two people....
I need to make a spool rack that fits in side with center bearings in order to roll it off by my self.

What on earth are you going to do with that stuff once you get the straps off? A roll of 1/8" thick material is not going to flatten out easily. Ever seen the machines they use for straightening coiled material? They're big and they make a lot of noise when the material is passing through...
