The GRP Dryfix Slate Valley Trough 3m (GDFVTUB105) is a specialized, mortarless valley system engineered specifically for slated pitched roofs. Manufactured from high-grade Glass Reinforced Polyester (GRP), it provides a lightweight, exceptionally durable, and completely weatherproof drainage channel where two roof slopes meet at an internal angle.
 
Featuring a 3-meter length with a dedicated profile optimized for slate thickness and lap dimensions, this valley trough incorporates specialized side upstands and water-check channels that prevent wind-driven rain from penetrating the roof space. Its robust composite construction delivers complete immunity to rust, rotting, and UV degradation, avoiding the high costs and theft risks associated with traditional lead valleys.
 
Designed for fast, secure under-batten fixing without the need for wet mortar beds, the GDFVTUB105 accommodates building movement and thermal expansion effortlessly. It offers professional roofers and contractors a clean, maintenance-free, and fully regulation-compliant solution for managing heavy rainwater runoff in valleys on both residential and commercial slate installations.

Available in standard Lead Grey. Dimensions 3000mm x 400mm, central upstand height : 105mm.
