Trygg tire chains are manufactured from alloyed steel which contain chrome, manganese, nickel and boron, and in some cases nickel and titanium. The chains are hardened to perfection.

All tire chains are constructed from two layers of steel. The outer layer is carbon-rich for wear resistance and the core is manganese/chrome alloy for increased toughness.

All studs and lugs are over-sized and made of boron alloyed steel to ensure the maximum core hardness.
