The GRP Tile Valley Strip Trough 3m is a versatile, high-performance drainage component engineered to create a secure, weatherproof valley on standard interlocking tiled roofs. Manufactured from durable Glass Reinforced Polyester (GRP), it provides a strong, lightweight, and corrosion-resistant alternative to traditional lead or zinc valley linings.
 
Featuring a 3-meter length, this valley strip is designed with a profiled central V-channel and wide upstands that safely capture and discharge high volumes of rainwater directly into the gutter system. Its robust composite build offers exceptional resistance to UV radiation, heavy frost, and environmental pollutants, ensuring it will not split, crack, or degrade over time.
 
Engineered for straightforward installation, the GRP valley strip can be fixed directly to timber sarking boards or open rafter setups beneath standard tile courses. It provides a clean, professional, and maintenance-free finish that completely removes the need for wet mortar bedding, ensuring reliable long-term performance across residential and commercial roofing projects.
