Square Protrusion Cast Iron Gully Grate For Waterflow
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 technical specifications or quotes, please contact professional manufacturers or suppliers.
