Big Drain for Main Roads
Main roads may need to handle more rainwater than side streets, so they require drainage covers with larger openings. These Cast Iron Gully Covers are designed for this application. The clear opening measures 600×600 mm. Ductile iron provides a strong body, with an asphalt paint coating on the surface. The tall frame provides space for drainage and is suitable for vehicle road rainwater drainage.

Wide Opening, Tall Frame
The frame outline measures 755×755 mm, and the frame height is 100 mm. This model does not include a locking system. Its D400 load rating provides heavy-load capacity for vehicle road applications. The tall frame and large opening are suitable for areas with high rainwater flow on main roads. Custom logos are available upon request.
