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" bottoms which prevents ezo ends from unintended opening when stacking the cans. This performant bottom also allows downgauging to 0.16mm using DR-plate.
The patented side wall bead can allows further downgauging to 0.14mm saving > 100,000 $ per line and year. The beads which have been ment to be covered by paper labels turned out to become a marketing feature using direct printing with even readable bar code.
The DRD-rule can diameter > height which is demonstrated with the 83 x 86mm "Bonduelle" can is no longer valid when other aspects such as contamination by internal laquers (BADGE) and welding seam repair issues come into play.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.
