Square Ductile Iron Manhole Cover

A square ductile iron manhole cover is a type of cover that is used to cover manholes in roads, sidewalks, and other areas. It is made of ductile iron, which is a type of iron that is more flexible and durable than traditional cast iron. The square shape of the cover allows it to fit tightly over a square manhole opening, providing a secure seal that prevents debris and other materials from entering the manhole. Ductile iron manhole covers are also resistant to corrosion and wear, making them a popular choice for use in areas with heavy traffic or harsh environmental conditions. They are often used in municipal and industrial applications, such as sewer systems, water treatment plants, and utility tunnels. item value Place of Origin hebei Brand Name xingbai Model Nu…
