Product Description
Our ductile iron manhole covers and frames are engineered for strength, safety, and versatility, making them the ideal choice for municipal, industrial, and commercial applications. Cast from EN-GJS500-7 or EN-GJS600-3 ductile iron, these covers combine high load-bearing capacity with exceptional resistance to wear, corrosion, and deformation.
Available in multiple shapes and load classes (B125 to F900), each cover is paired with a precisely cast frame to ensure secure seating and long-term performance. Surface coatings such as bitumen or epoxy provide additional corrosion protection, while gaskets and locking options improve sealing and security.
Typical applications include sewer systems, roadways, utility access points, and water management infrastructure. All covers and frames are cast using advanced sand casting processes and tested according to EN124-2015 standards.
