General information about The 3-PC tinplate can

 

The tin coating is applied by continuous electro-deposition of tin on to thin steel strip, after which the tinplate is either sold in coil form or cut into sheets for the can manufacturer.

 

At the can manufacturers, the tinplate is slit into rectangular “body blanks” which are then rolled into a cylindrical shape and the contacting edges welded together at very high speeds. The ends of this cylinder are flanged, ready to receive the can ends.

 

Corrugations known as “beads” are often rolled into the cylinder walls for added strength.

 

The can end is applied forming the “open top can” which is then supplied to the food canning company.
