This, the first of two short videos shows the edges of boilerplate being pressed to prepare the edges so there is no flattening at the seam – ready to be used on our bronx pyramid roll set.
The plate is 20 mm thick BS 1501 225 490B LT50 and is at the maximum capacity for these rolls:

Other grades of carbon steel plate used for pressure vessels include :
