Product Description
Our Water Supply Ductile Iron Manhole Covers are specially engineered to meet the hygiene, safety, and durability demands of municipal and industrial water supply systems. Manufactured from high-quality EN-GJS-500-7 ductile iron, they offer high strength, long service life, and leak-tight sealing.
The covers are typically finished with food-grade blue epoxy coating to ensure corrosion resistance and water quality safety. A neoprene gasket provides reliable water-tight sealing, effectively preventing infiltration or contamination.
Designed in accordance with EN124 and ISO 9001 standards, these covers are ideal for underground fresh water pipeline networks, water utility chambers, and meter boxes. Anti-slip surface textures and optional stainless steel locking mechanisms add to their reliability and security.
