Different types of corner beads are designed for specific applications, environments, and performance needs. Understanding the various types of corner beads and their uses helps builders, contractors, and homeowners choose the right solution for durable, crack-free, and professional finishes.
Why Choosing the Right Type of Corner Bead Matters
Each corner bead type offers unique advantages in terms of strength, moisture resistance, flexibility, and finish quality. Using the correct type ensures better edge protection, reduced cracking, and long-term durability, especially in high-traffic, humid, or stress-prone areas.
