Company History

Established in 1978 to produce wire die springs, Special Springs became in just a few years the first global company in the sector to offer 3 different standards: ISO 10243, JIS B5012 and US Oval Wire. Nitrogen gas spring production began in the late 1980s as a natural complement to our wire springs. Special Springs Italy currently operates facilities assigned specifically to wire springs and nitrogen cylinders, with a total production area of more than 100,000 sq ft.
