High Toughness Decorative Ductile Iron Manhole Cover Spray Paint
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.

Product Features:
(1) High strength and durability
Square cast iron manhole covers are made of high-quality cast iron,
which has high compression and bending resistance and can withstand
the weight of vehicles and heavy equipment.
The strength of manhole covers made of ductile iron is close to
that of carbon steel, and they have good seismic resistance and a
service life of more than 20 years.
(2) Anti-slip design
The surface is usually designed with anti-slip patterns (such as
grids and radial patterns), which can effectively prevent slipping
even on rainy days and ensure the safety of pedestrians and
vehicles.
(3) Anti-theft and anti-falling
Square manhole covers can be equipped with safety locks or hinge
structures to prevent the manhole covers from being stolen or
shifted.
The hinged design can also prevent accidental falling when opening
the manhole cover, ensuring the safety of installation and
maintenance.
(4) Drainage performance
Some square cast iron manhole covers are designed with air vents or
drainage holes to prevent rainwater accumulation and reduce the
impact on road traffic.
(5) High dimensional accuracy
The square manhole cover is tightly matched with the base (manhole
frame) to prevent shaking or noise.
(6) Multiple load-bearing levels
Square cast iron manhole covers are divided into six load-bearing
levels according to the EN124 standard: A15, B125, C250, D400, E600
and F900, meeting various needs from pedestrian areas to heavy-load
areas.
