The aim of this research paper is to study the ultimate and service behaviour of ferro-cement roof slab panels and the comparative study of panels via using welded square mesh and expanded mesh. The test results of four different panels of 20 mm thick having number of layers varying one to four presented. The parameters of study include: the effect of the percentage of wire mesh reinforcement by volume and the structural shape of the panels on the ultimate flexural strength, first crack load, crack spacing and load-deformation behaviour. The results indicate that the use of monolithic shallow edge ferro-cement beams with the panels considerably improves the service and ultimate behaviour of the panels, irrespective of the number of steel layers used.
