For a fixed set X, an arbitrary \textit{weight structure} d∈[0,∞]X×X can be interpreted as a distance assignment between pairs of points on X. Restrictions (i.e. \textit{metric axioms}) on the behaviour of any such d naturally arise, such as separation, triangle inequality and symmetry. We present an order-theoretic investigation of various collections of weight structures, as naturally occurring subsets of [0,∞]X×X satisfying certain metric axioms. Furthermore, we exploit the categorical notion of adjunctions when investigating connections between the above collections of weight structures. As a corollary, we present several lattice-embeddability theorems on a well-known collection of weight structures on X.
