Prior to the metal casting process, key mineral additives are added to ductile iron to produce an extremely resistant and durable metal. The molecular structure of ductile iron gives it exceptional extra strength and resistance to shock loads, with the same structure as carbon steel, but without the corrosion. On today’s roads, manhole covers and gratings are required to carry increasingly heavier and faster moving traffic, but in order to keep roads open and avoid accidents and theft, these manhole covers and gratings are subject to additional requirements in terms of speed and ease of maintenance service. Ductile iron is rapidly replacing traditional grey cast iron manhole covers, gratings and frames due to its unique strength to weight ratio, design, weight and cost effectiveness.

ADVANTAGES OF 'DUCTILE IRON' MANHOLE COVERS, FRAMES & GRATINGS:

High Strength, results in More Life and Durability

Available with Elegant Checkers Design, offers Good Anti- skid Grip and Nice Appearance.

Due to it's Hinge type Design, Chances of Theft are Less.

Suitable for Heavy Traffic Loading and at High speed.

Chances of Accidents are almost Reduced, as it Does Not Break Suddenly.

Due to High Strength, 'Ductile Iron' Minimises the Risk of Failure during normal uses and offers Resistance to Impact.

Ductile Iron's High Strength to Weight ratio allows the manufacturers to relatively manufacture Light Weight Castings, offering up to 50% Weight Savings over Grey Iron Castings, subsequently Saving in Cost Per Piece.

Lightweight Castings offer Cost Benefits, from Transportation to Installation, providing Ease of Handling and Maintenance during service.
