Mondo Knows Facts

Ribs and beads let tin cans use thinner steel

Rolled grooves act as stiffeners so the wall resists crushing without weight A smooth cylinder of very thin steel buckles easily, but pressing circumferential beads into the body turns the wall into a series of shallow arches that resist inward pressure. That allows lighter cans and less metal per unit, which matters when billions are made each year. Larger food cans carry deeper beads because the vacuum inside pulls the walls inward. It sits in Mondo's everyday life collection, one of 200 facts that each trace back to the reference below.
