A corrosion resistent protective plastic overlay is intimately engaged with the chime of a fibre drum and extends from an inner edge portion thermally bonded to the drum lining over the bead and into the exterior chime groove. The overlay is fusion bonded to the chime throughout the full extent of the surface-to-surface engagement therebetween.
