  In this article, we study thin shells of matter connecting charged black
string geometries with different values of the corresponding parameters. We
analyze the matter content and the mechanical stability of the shells
undergoing perturbations that preserve the cylindrical symmetry. Two different
global configurations are considered: an interior geometry connected to an
exterior one at the surface where the shell is placed, and two exterior
geometries connected by a wormhole throat located at the shell position.
