Expanded Corner Bead
Share to：
Expanded Corner Bead is a perforated metal trim designed to create straight, durable outside corners in plaster and stucco wall systems. The expanded flanges embed securely into the base coat, providing a strong mechanical key and improved bonding along the edge. By reinforcing vulnerable corner areas, Expanded Corner Bead helps resist impact damage, chipping, and cracking while delivering sharp, clean lines for a professional finish. Compatible with interior and exterior applications, it simplifies corner alignment and contributes to long‑lasting, uniform stucco and plaster surfaces in residential and commercial projects.
