Product Description
Product Name: Heavy Duty Ductile Iron Casting Manhole Cover/Sewer Lid
Category: Manhole Cover
Manhole covers are covers used to cover deep wells on roads or in homes to prevent people or objects from falling. According to materials, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc.
Manhole covers have diverse materials and types. For example, cast iron manhole covers are divided into ductile iron manhole covers and gray cast iron manhole covers. The compressive capacity of ductile iron manhole covers is stronger than that of gray cast iron manhole covers. The new anti-settlement manhole cover is made of ductile iron. Through the self-contracting well structure and the design of the bottom adjustment ring, it can effectively avoid rainwater corrosion and rust and reduce noise generation.
