PU edging screen combines high-quality polyurethane material with a high-strength metal screen. Its edging design not only enhances the sealing and fixing effect of the screen but also effectively prevents material damage to the screen. It extends its service life, and improves the overall stability of the screen, ensuring a more efficient and reliable screening process. It is an ideal choice for high-strength screening environments.
