**Abstract**

Several lattice structures that can be thought as graphs are useful in the study of large networks. In this work, we study 15 topological graph indices from the class of Zagreb indices of some interesting lattice structures called snake graphs. We use vertex and edge partitions of these graphs and calculate their indices by means of these partitions.
