About
Cast iron and ductile iron manhole covers and gratings are essential components used in infrastructure systems for access to underground utilities such as sewer lines, stormwater drainage systems, and utility tunnels. They are designed to cover openings in the ground, providing secure access points for maintenance, inspection, and repair activities.
Here's a breakdown of each component
:
Manhole Covers: These are heavy-duty lids that sit flush with the surface of the ground and cover access points to manholes or utility vaults. Manhole covers are typically circular or square in shape and are made of either cast iron or ductile iron to withstand heavy loads, traffic, and environmental conditions. They often feature raised patterns or embossments on their surface to enhance traction and prevent slipping.
Gratings: Gratings are similar to manhole covers but are typically used to cover larger openings such as trench drains, catch basins, or culverts. They consist of a framework with openings or gaps to allow water to flow through while preventing the passage of large debris or objects. Like manhole covers, gratings are made of cast iron or ductile iron for durability and strength.
