According to official Guinness World Records, the largest aluminum beverage can was manufactured by Vitalon Foods Co. Ltd and displayed at the Chiang Kai-Shek Memorial Hall Plaza in Taipei, Taiwan, in June 2002. With a height of 4.67 meters (15.32 feet) and a diameter of 2.32 meters (7.61 feet), the can was an enlarged version of the Vitalon “SUPER SUPAU” sports drink.
The colossus, capable of quenching the thirst of some 25,000 people (but only if equipped with a suitable straw ) weighed 4,400 kg (9,700 lb) when empty and had an official capacity of 8,460 liters. According to information gathered (and translated from a Chinese-language website), it took Vitalon five months to manufacture it from the most advanced high-tech aerospace aluminum alloys. The major difficulty in building such giants is that, after filling them with the beverage, the high pressure should not deform or expand them at all.
Therefore, the can body was manufactured from multilayer materials using high-tech aviation technology. I could not find any information about the profiles of the locking rollers, but I am afraid they could not use the standard R96F and S167 (Roberto Baroni).
