Ductile Iron

Ductile iron is key to the superior performance of PAM products. This engineered material is lighter and stronger than cast iron, the traditional choice for manhole covers, curb units and gratings. ductile iron conforms to the ASTM A536 standard, and offers a number of ergonomic and functional advantages not available from ordinary cast-iron alternatives:

• Elasticity
• Strength and durability
• Impact resistance
• Light weight
• Designability
• Predictably mechanical performance

One-Man Operable

• Easily operated by one person using standard tools.
• Hinged design lessens the risk of serious back and other injuries.

Reduced Infiltration

• Elastomer gasker rind decreases inflow of excess water.
• PAMTIGHT covers provide complete water tightness.

Anti-Theft

• Standard integral spring bar lock activates automatically upon closure.
• Optional locking systems available for additional security.

Increased Water Clearing Capacity

• Gratings feature large waterway areas.
• Design maximizes absorption in all flow conditions.

Loading

• All PAM units exceed AASHTO H20 heavy-duty loading standards.

Automatic Surge Release

• Hinged covers allow release of built-up pressure.
• Covers return to closed, traffic-safe position.

Odor Control

PAMTIGHT air- and watertight covers also prevent escape of unpleasant odors.
