Corner Bead 90 deg or L Shaped

A corner bead is a protective and finishing profile used in drywall and plaster applications. It is installed along the external corners of walls to:

• Protect corners from impact and wear.

• Create clean, straight, and sharp corner lines.

• Provide a smooth surface for painting or finishing.

Corner beads can be made from metal (galvanized steel, aluminum), PVC, or paper-faced metal depending on the application. They are typically installed by nailing, screwing, or embedding in joint compound.

Standard Lengths

Corner beads come in different lengths to match the height of walls and reduce the number of joints needed. Common lengths include:

1. 8-foot (8') Corner Bead

   • Ideal for standard 8' ceilings.

   • Minimal seams, easy to handle.

   • Often used in residential homes.

2. 9-foot (9') Corner Bead

   • Designed for 9' walls.

   • Reduces joints in rooms with higher ceilings.

   • Provides a clean, continuous corner finish.

3. 10-foot (10') Corner Bead

   • Used for taller walls or commercial spaces.

   • Helps minimize taping and mudding joints.

   • Can reduce labor time on high walls.

4. 12-foot (12') Corner Bead

   • Best for high ceilings or long continuous walls.

   • Reduces seams to almost zero in most rooms.

   • Often used in large commercial or industrial applications.
