A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use:

Chains are a critical component in many industries, providing strength and flexibility while withstanding tension. From power transmission to decoration, different types of links provide unique characteristics suited for various purposes—from the small-scale jewelry chain to giant industrial designs that drive complex operations. For all their diversity though, they share one common feature: an assembly of multiple connected pieces creating something greater than its parts alone could achieve!
