What Makes Crescent Foundry Manhole Cover Solutions Worldwide Famous?

The credit for the superior  quality castings could be given to the Ductile Iron  material used in manufacturing of manhole cover solutions.  Manhole Covers, Gratings and Frames are made from Ductile Iron which receives crucial mineral additives prior to the casting process. The end material thus produced is highly durable and strongly resistant.

  • Ductile iron used to cast manhole covers and gratings has a unique strength to weight ratio, design and cost effectiveness and can withstand the load of fast moving and increasingly heavy traffic at ease
  • These ductile iron Airport Manhole Covers are aesthetically appealing with elegant checker designs
  • These ductile manhole covers come with hinge type design in order to avoid theft
  • Ductile iron manhole covers reduce the chances of accidents as the sturdy material has a high resistance to impact and offers a great anti-skid grip
  • The manufacturer of Airport Manhole Covers uses ductile iron for its relatively lighter weight that provides ease of handling and maintenance during service.

Catch Basin Covers

Catch basins serve as the backbone in a landscape drainage system. They are available in various sizes and materials; these are boxes placed in the ground near areas of standing water to help facilitate proper water drainage and avoid the risk of  property damage. Catch Basin Covers or hooded inlets prevent floating materials and trash from entering the storm drain system. The inclined screen mounted in front of catch basin inlet strains trash that enters the catch basin from getting into the storm sewer system.
