    Abstract. The article examines the influence of the choice of steel grade on the operation of elements of steel lattice structures of coatings using the example of a metal truss. A finite element simulation of a farm has been performed, the elements of which are obtained as a result of cutting an I-beam. The calculation series includes various grades of steel for load-bearing metal structures, as well as structural carbon and alloy steels. Additionally, the influence of welding wire grades on the allowable force in the weld was investigated. The calculations were performed in the ANSYS Workbench software package in a linearly elastic formulation with step loading (hinge fasteners, the load is a concentrated force in the node). It is established that the replacement of base steel with more durable grades leads to an increase in the maximum load. According to the criterion of maximum deformation, the permissible loads vary in a narrow range, which confirms the decisive role of stiffness and structural factors in the adopted scheme. For welded joints, it is shown that the choice of wire significantly affects the allowable force in the seam. The most cost-effective steel grades in comparison with the basic steel variant have been identified.
