Cast Iron grating

The advantage of cast and ductile iron grates is their strength, coming directly from the manufacturing procedure, where they are poured as a single unit, not requiring secondary joins in the design.

Cast iron grates in Class B (light duty), Class C (medium duty) and Class D (heavy duty) of En124.

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.
