When you say heavy, what thickness?

3mm, 6 mm, 10 mm or more?

I've seen curves being put into 70 mm plate, thats another story

I have worked in tank storage all my adult life, construction, repair and inspection so have had a fair bit of involvement with plate forming but in a sinlge plane (up to 44mm)

I might be able to piut you in touch with companies who do this sort of thing.

What size ar you looking at?

sorry should have said its 12mm plate probably as big as we can get away with, but say around 1.5x3m for now...

Concrete mould with lots of drainage channels -place in disposable pool full of water - plate on top - explosives on top of that - raincoat - BANG - lots of warm rain - plate formed

Needs one pool per plate

Steel yachts have been made this way.

Here it is

Try Barnshaws, they seem to bend/roll most things, have used them to roll 50mm plate to approx 500mm dia.
