Basis Information
Detailed description of square cast iron manhole cover
Square cast iron manhole cover is a product used to cover underground pipe wells, mainly used in municipal engineering, road facilities, residential areas, industrial parks and other scenes. It not only protects underground facilities and prevents debris or rainwater from entering the pipes, but also provides pedestrian and vehicle traffic safety. The following is a detailed description of the square cast iron manhole cover:
1. Product Introduction
Square cast iron manhole covers are cast with high-quality cast iron materials (such as ductile iron or gray cast iron) and are square or rectangular in shape. The square design is particularly suitable for wells in fixed positions and is more adaptable than round manhole covers in some special scenarios, such as square wells or sites that require large spans.
2. Product Material
Depending on application requirements, square cast iron manhole covers are generally made of the following two materials:
Ductile Iron:
High strength, good toughness, and superior compressive resistance.
Strong corrosion resistance, suitable for long-term outdoor use.
It has good fatigue resistance and can withstand high traffic frequency and heavy loads.
Gray Iron:
It has good pressure bearing capacity and is suitable for light or medium load areas.
It has relatively low cost and better economy.

| 1000 × 1000 | 900 × 900 | 50 | E600 | 120 | Industrial zones, heavy vehicle areas |
A15: Suitable for pedestrian paths, parks, and non-traffic areas.
B125: Designed for sidewalks, residential paths, and non-motorized lanes.
C250: Suitable for medium traffic areas like parking lots and secondary roads.
D400: Ideal for urban main roads and motorized traffic areas.
E600: Designed to handle heavy-duty loads for industrial zones and logistics parks.
Manufacturing Process
Material Preparation: High-quality pig iron and scrap iron are melted together, with magnesium added to create a ductile iron alloy.
Casting: The molten iron is poured into molds to form the basic shape of the manhole cover. Sand casting is a common method due to its precision and efficiency.
Heat Treatment: The cast pieces are treated with heat to improve strength and flexibility.
Surface Coating: Anti-corrosive coatings are applied to ensure longevity in various environments.
Quality Control: Each cover undergoes rigorous testing for load-bearing capacity, tensile strength, and dimensional accuracy.
