Square Protrusion Cast Iron Gully Grate For Waterflow C250 Gully
Grating
Producte Introduction:
The cast iron convex manhole cover square overflow well is an
important equipment used in municipal drainage systems, mainly used
for overflow control in rainwater or sewage systems. It is made of
sturdy and durable cast iron material, with a raised manhole cover
to prevent water backflow and overflow. The structure is usually
square and suitable for covering and protecting the overflow well
opening.
This product is widely used in urban drainage systems, industrial
parks, residential areas and other places where drainage facilities
are required. Its main function is to quickly discharge excess
rainwater or sewage, prevent water accumulation, and protect the
equipment and system in the well.

Product Characteristics:
Material advantages
Cast iron material: Made of high-strength cast iron (such as
ductile iron or gray cast iron), it has excellent bearing capacity,
pressure resistance and impact resistance.
Strong corrosion resistance: The surface is specially treated (such
as spraying asphalt or epoxy coating) to prevent the manhole cover
from rusting in a humid or corrosive environment.
Raised design
The raised design on the surface of the manhole cover can
effectively prevent water backflow, especially in extreme weather
conditions such as heavy rain, to ensure that the water flows
smoothly into the overflow well.
The raised part can also prevent mud and large particles from
entering the drainage system, reducing the risk of blockage.
Square design
The square manhole cover design makes it more secure to cover the
wellhead and is suitable for installation needs in various
scenarios.
The corner design of the square manhole cover facilitates equipment
installation and maintenance, and improves the overall convenience
of operation.
Anti-slip and safety
The surface usually has anti-slip texture, especially in rainy or
slippery environments, which can effectively prevent pedestrians
from slipping and vehicles from skidding.
Equipped with a safety lock or hinge design to prevent the manhole
cover from being stolen or accidentally moved, ensuring the safety
of pedestrians and vehicles.
Strong load-bearing capacity
According to different usage scenarios, the load-bearing capacity
is divided into multiple levels (in accordance with international
standards such as EN124), suitable for use from pedestrian areas to
heavy vehicle areas.
Customized Service:
Size and specification: Non-standard sizes can be manufactured
according to customer needs.
Surface treatment: Different coating options are available (such as
asphalt paint, epoxy resin, hot-dip galvanizing).
Personalized logo: Supports customized company logo, municipal
number or project name.
Intelligent upgrade: Can integrate intelligent devices such as
water level monitors and pressure sensors for modern drainage
management.
Cast iron convex manhole cover square overflow well is an
indispensable and important part of modern municipal and industrial
drainage systems. Its durability and high performance make it an
ideal choice for complex drainage needs. For more detailed
