Metal Corner bead Size

Standard Metal Corner Bead Sizes

The most common dimensions for metal corner beads are:

• Flange Width: Typically 1-1/4 inches on each side. This size offers a balance between strength and ease of finishing.

• Length Options: Standard lengths include 8 ft, 9 ft, 10 ft, and 12 ft, catering to various wall heights and construction needs.

For instance, Grip-Rite offers metal corner beads in these standard sizes, ensuring compatibility with most drywall applications. 

Specialized Variants

Beyond standard sizes, there are specialized metal corner beads designed for specific applications:

• Bullnose Corner Beads: These feature a rounded profile, typically with a 3/4-inch radius, providing a softer aesthetic compared to traditional sharp corners. They are available in lengths of 8 ft, 9 ft, and 10 ft. 

• Expanded Flange Beads: Some metal corner beads come with expanded flanges, enhancing the bonding surface for joint compounds and ensuring a more secure attachment to the drywall.
