corner bead trim angle 30x30mm drywall system installation
Corner beads give drywall installations a precision finish. A corner bead allows outside corners where two materials meet each other to be seamlessly joined without having to repeatedly cut and fill in the gap between them. Not only do corner beads provide a quality finish, they also improve the durability of your drywall. There are a multitude of options depending on the type of finish a project requires.
Metal Corner Beads
Metal corner beads are one of the more regularly used corner beads. Made from galvanized steel, they are rust resistant and provide a pointed corner for a clean finish. Metal corner beads can be installed in a variety of ways, including being nailed or screwed in, stapled or attached with an adhesive.
With slight modifications, they can be molded to curved arches. However, this flexibility also leaves them vulnerable to twisting during installation. The finish of a metal bead can also affect how well they can be mudded in. Certain finishes will perform better than others, which is why some suppliers will add a gypsum laminating paper to the outer face, assisting the finishing product to adhere to the bead.
