Product Description
This Heavy Duty Ductile Iron Manhole Cover is specifically engineered for high-traffic and heavy-load environments, including highways, shipping terminals, and industrial driveways. Made from high-strength ductile iron such as EN-GJS-500-7 or EN-GJS-600-3, it delivers long-term durability, superior impact resistance, and excellent load performance.
Our castings are manufactured using advanced resin sand or green sand molding technology to ensure uniformity and dimensional accuracy. A range of surface patterns and custom branding can be incorporated based on project specifications. Optional anti-theft locking mechanisms and sealing gaskets enhance safety and leak prevention in municipal and commercial utility installations.
