Metal Corner Tape: Flexible Strength for Flawless Drywall Corner Finishing
Metal corner tape is a high-performance finishing accessory designed for reinforcing and protecting drywall corners. It combines the strength of metal with the flexibility of paper or fiber backing—making it ideal for creating sharp, crack-resistant corners in both internal and external drywall applications.
Whether you're finishing a new room, repairing damaged corners, or achieving a clean architectural look, drywall corner reinforcement using metal corner tape ensures professional, long-lasting results.
What is Metal Corner Tape?
Metal corner tape is a composite drywall product made from two galvanized steel strips bonded to a paper or fiber tape. The steel provides strength and dent resistance, while the paper surface ensures smooth adhesion and finish with joint compound.
Unlike rigid corner beads, metal corner tape is flexible and can be folded to fit both 90° angles and custom off-angle corners. It is commonly used during the taping phase of drywall installation to reinforce outside corners and prevent cracks or chipping over time.
Key Features of Metal Corner Tape
- Strong Reinforcement: Galvanized steel strips resist dents, impacts, and cracking.
- Flexible Design: Easily bends to suit straight or off-angle corners.
- Smooth Finish: The paper-facing blends seamlessly with joint compound and paint.
- Rust-Resistant: Coated steel ensures long-lasting durability even in humid interiors.
- Easy Installation: Cuts with scissors and installs with standard drywall compound.
Major Uses of Metal Corner Tape
1. Drywall Corner Finishing
The primary use of paper-faced corner bead is to reinforce and finish drywall corners with precision. It’s applied over external corners to prevent damage from bumps, furniture, and wear.
2. Off-Angle Corner Reinforcement
Thanks to its flexible center crease, metal corner tape can be folded to match any angle—ideal for vaulted ceilings, staircases, and non-standard wall designs.
3. Repairing Damaged Corners
Used to repair cracked or broken corners on existing walls, restoring structure and a clean appearance without full rework.
4. Interior Renovation Projects
A preferred product for remodelers and contractors due to its lightweight, fast installation and reliable performance.
5. Commercial & Residential Drywall Systems
Equally effective in homes, offices, hospitals, schools, and high-traffic environments where durability is key.
