In this paper, we give some results on the preservation of orderings between the components under the formation of coherent systems with different structure. We consider the stochastic and failure rate orderings to compare two coherent structures formed from two sets of components, in both cases, when components are independent and either identically distributed or not necessarily identically distributed. As a consequence, we obtain some results given by other authors and we get new stochastic comparisons of systems with different k-out-of-n structure.
