The NRG External Bead 3.5mm X 3m is the industry standard for creating perfectly straight, impact-resistant external corners on rendered wall systems. Manufactured from high-impact, UV-stabilized PVC, this bead is designed to withstand the harsh Australian climate. Unlike traditional metal beads, the NRG External Bead will never rust or corrode, preventing “bleeding” through the render and ensuring the long-term aesthetic of your facade.
