Ductile iron manhole covers are a type of manhole cover used to cover underground facilities such as highways, streets, and squares. It is made of ductile iron material and has characteristics such as high strength, corrosion resistance, wear resistance, and good compressive performance. The surface of ductile iron manhole covers can be treated with anti slip treatment to prevent pedestrians or vehicles from slipping or slipping on rainy or slippery roads.
Ductile iron manhole covers usually consist of two parts: manhole covers and manhole seats. The manhole cover is the part covering the wellhead, while the manhole seat is the part fixed below the wellhead. The design of ductile iron manhole covers can be customized according to needs to meet different usage requirements. For example, different thicknesses and sizes can be selected based on different load requirements, or anti-theft devices can be added to improve the safety performance of manhole covers.
Ductile iron manhole covers are a high-quality and high-performance manhole cover product widely used in public places such as urban roads, airports, docks, and squares. It has good waterproof, dustproof, odor resistant and other characteristics, which can effectively protect the safety and reliability of underground facilities.
Ductile Iron Manhole Cover is made from spheroidal graphite Cast Iron by machining hand moulding, solid top, recessed,double triangular, single seal or double seal, square or rectangular or round,with or without hinge. Very good quality, smooth and free from sand holes, blow holes, distortion or any other defects. Loading capacity is 40 tons. The normal coating is black bitumen 30 microns thickness, also can make the epoxy coating according to the customer’s demand.
