Metal drywall beads and trims are traditional reinforcement and finishing products used in gypsum wallboard construction. Metal beads and trims provide crisp, clean and straight protection for drywall corners. The most common metal trim is drywall corner bead. Corner bead is applied to 90 degree exposed outside gypsum corners to provide a strong, durable, straight, crisp finished corner. Metal beads and trims are nailed, screwed, stapled or clinched in place and finished with joint compound. They are low cost easily applied and provide high-quality, long lasting professional finishes. Hot-dipped galvanized corner bead is a highly durable metal corner reinforcement that offers superior corrosion protection. This bead is ideal for humid, moisture-prone conditions and high-traffic areas subject to more than normal abuse.
