In this publication, the authors present the results of their own research into the loading of a commercial concrete component that forms part of the load-bearing structure of an openwork wall. The finite element method was used for the analysis. Based on the numerical model developed and the boundary conditions adopted, maximum stresses of 204 MPa and displacements of 9 mm were obtained. The simulation model adopted enabled the identification of critical areas of the product, which were confirmed by laboratory tests. The results obtained from the simulation were validated using a tensile testing machine with the 15x15 procedure implemented. Based on the tests carried out, a casting mould design was developed, which was used to manufacture the products in question. The tests utilised components made of C30 concrete, which had been cured for 28 days in the open air. The laboratory tests confirmed the presence of critical areas prone to cracking, as indicated in the simulation studies. Ultimately, it was concluded that the selected material and the product’s geometry meet the operational requirements.
