Angle Bead (Corner Bead) - Professional Introduction

An angle bead, also known as a a corner bead, is a crucial plastering and drywall accessory used to form, reinforce, and protect external corners on walls and ceilings. It is a fundamental component in modern construction, ensuring a clean, straight, and durable finish.

Key Features & Structure:

· Material: Typically made from galvanized steel, stainless steel, or durable PVC.

· Design: Features an L-shaped cross-section, with perforated wings on each side. The external corner is a sharp, precise 90-degree angle.

· Function: The wings are embedded into the plaster, skim coat, or joint compound, while the solid external spine acts as a guide and a protective arris.

Primary Functions & Benefits:

1. Creates a Perfect, Sharp Corner: It provides a straight, true 90-degree edge that is difficult to achieve freehand, resulting in a professional-looking finish.

2. Reinforces and Protects: The bead acts as an impact-resistant shield for the otherwise vulnerable plaster corner, preventing chipping, cracking, and other damage from accidental impacts.

3. Guides Application: It serves as a visual and physical guide for the applicator, allowing for easy and consistent application of plaster or joint compound on both sides of the corner.

4. Long-Lasting Durability: Made from corrosion-resistant materials, it ensures the integrity of the corner remains intact for the lifetime of the wall system.
