ABSTRACT:
A corner bead for drywall construction has a galvanized steel core strip which is formed with a central portion, side flanges, and shoulders joining the central portion and side flanges. The front face of the core strip is covered with a paper layer having an outer protective coating thereon overlying the central portion adjoining said shoulders. A paper reinforcing layer covers the back of the core strip in one embodiment to minimize the thickness of the core strip.
