Abstract
A chain comprises interconnected links with each link comprising opposed C-shaped ends joined by joining limb portions. Each C-shaped end includes a central crown with shoulders on either side of the crown, and by the present invention the section modulus about an axis perpendicular to the plane of the link of a cross-section at a shoulder is greater than the corresponding section modulus of a cross-section at the crown, and preferably additionally said section modulus of the section at the shoulder is greater than a corresponding section modulus of a cross-section at the associated joining limb portion.
