DRD Draw-Redraw lines have been built by AH since 1982 starting with the typical tomato paste cans in Italy. Throughout the years we developed the "tab safe" bottom which prevents ezo ends from unintended opening when stacking the cans. This performant bottom also allows downgauging to 0.16 mm using DR-plate.
The patented side wall bead can allows further downgauging to 0.14 mm saving > 100,000 $ per line and year. The beads which have been meant to be covered by paper labels turned out to become a marketing feature. Even readable bar code could be printed on, using direct printing.
The DRD-rule can diameter > height which is demonstrated with the 83 x 86 mm "Bonduelle" can is no longer valid when other aspects such as contamination by internal laquers (BADGE) and welding seam repair issues come into play. This led to the development of high cans made from laminated steel.
