Metal Corner Tape (5CM * 30M)

Also known as metal corner bead or corner guard, the corner tape is a construction material used to reinforce and protect the corners of walls during drywall installation. It's typically made of metal (aluminum or galvanized steel) and is designed to provide a straight, durable edge that helps prevent damage to the corners from impacts or settling. Metal corner tape is applied to corners before drywall mud (joint compound) is applied over it to create a smooth finish. This helps achieve crisp corners that are resistant to cracks and dents over time.
