fire-rated metal corner bead

A fire-rated metal corner bead is a specially designed drywall finishing accessory that not only reinforces corners but also meets fire-resistance requirements in commercial and residential construction. It’s typically used in fire-rated wall assemblies to maintain the integrity of fire barriers and rated partitions.

Key Features

1. Non-Combustible Material

   • Made from galvanized steel or stainless steel—does not burn, melt, or emit toxic fumes during a fire.

2. Code-Compliant

   • Meets ASTM E119, UL, or local fire safety code requirements when used as part of tested wall assemblies.

3. Durability Under Heat

   • Maintains structural form and does not warp or deteriorate at high temperatures.

4. Reinforced Protection

   • Prevents cracking and damage at corners, preserving the fire-rated drywall’s performance.

5. Smooth Finishing Compatibility

   • Easily integrates with fire-rated drywall, Type X gypsum boards, and fire caulking systems.

 Common Applications

• Commercial fire-rated drywall assemblies

• Fire-resistive corridors, stairwells, and elevator shafts

• High-rise residential and office buildings

• Hospitals, schools, and public facilities with strict fire codes

• Industrial buildings requiring non-combustible finishes

Installation Tips

• Use with fire-rated joint compound or firestop caulking to maintain UL-rated assembly integrity.

• Always verify compatibility with the full tested fire-rated wall system (e.g., UL-listed wall type).

• Fasten using fire-approved screws or anchors.
