D Type 3m Long Univ Valley Trough

Ideally suited for installation on roofs with pitches ranging from 17.5° to 55°, the Harcon Corodrain HD30 Standard D-Type Universal Valley Trough is a narrow valley trough intended for specific use with single lap tiles in limited scenarios. It has been crafted for compatibility with interlocking tiles as well as both natural and made-made slates, making it an endlessly versatile solution. Manufactured from GRP, a top-quality unfilled polyester resin with glass fibre reinforcement, it comes in a grey/blue colour. This standard HD-type valley includes a 35mm sanded strip designed to enhance mortar adhesion and can account for a maximum 15° variation between two rafter pitches. With durability akin to lead and a minimum lifespan of 30 years, its enhanced resistance to unintended harm makes it a reliable choice. It also comes with higher cost-savings compared to lead. The installation process is quick and seamless, and this robust alternative to lead is resistant to UV light and acid rain, with a smooth surface that deters the growth of moss, lichen and debris accumulation.
