TL;DR
Corner bead is the rigid profile, galvanized metal, vinyl, or paper-faced composite, installed over drywall outside corners to produce a straight, impact-resistant edge once buried in joint compound. Metal gets nailed or crimped, vinyl often staples or glues on, and paper-faced versions embed in compound for the cleanest finish with the fewest edge cracks.
What it means
Corner bead is the rigid profile, galvanized metal, vinyl, or paper-faced composite, installed over drywall outside corners to produce a straight, impact-resistant edge once buried in joint compound. Metal gets nailed or crimped, vinyl often staples or glues on, and paper-faced versions embed in compound for the cleanest finish with the fewest edge cracks. Dented or cracked beads from furniture strikes are among the most common drywall repairs, and bullnose variants create the rounded edges popular in southwestern interiors.
