Corner bead reinforces exterior stucco or plaster corners with durable, straight and rust free vinyl corners.
Vinyl corner beads are specially manufactured with striation and perforation along the flanges, which provide positive bonding of stucco to the product and substrates, which they are attached. These become part of the building structure and move along with the walls. However, these do not freely express their coefficient of expansion or contraction.
Corner beads are available in main versions : Sharp edge for fine corners, smooth edge for contemporaneous corners and bull-nose edge for soft corners.
The other version of corner beads can perform multiple functions such as angle constrained by narrow corner, walls with acute and obtuse angle and various curves to most of the construction radiuses.
