This work reports the results of measurements of the topography of 79 rough surfaces. The materials were stainless steel, mild steel, aluminium and copper. The surfaces of the specimens were blasted with particles of different materials at a range of pressures. It was found that profile heights were generally Gaussian. Simple correlations between measured parameters were developed. Analysis was also conducted of the effect of different cut off lengths. It was confirmed that roughness parameters are not intrinsic properties of the surface, but depend on the cutoff length
