What is better vinyl or metal corner bead?
Vinyl beads are inarguably superior to metal beads in two important ways: vinyl is dent-resistant and rust-proof. In contrast, vinyl beads excel in damp, moisture-prone areas. They are impervious to rust and water damage, so they will stand the test of time without damaging or discoloring the finished wall.
