It's a far superior alternative to bare metal. Made with strong paper tape laminated to a strong, corrosion-resistant metal form, Sheetrock® paper faced metal bead ensures excellent adhesion of joint compounds, textures and paints for a strong, smooth finish. Its tape-on profiles provide superior resistance to edge cracking and chipping for corners that stay beautiful even through structural settling and everyday wear and tear. In addition, the unique, patented green paper tape nose coating resists scuffing and fuzzing from knives and sanding during installation.
