Strip Opening Cast Iron Clark Drain Gully Grate
Producte Introduction:
Ductile iron rectangular heavy-duty gutter grate is a high-strength drainage equipment made of ductile iron. It is widely used in drainage systems that need to withstand high-strength loads, such as municipal engineering, industrial parks, port terminals, and airport runways. Its main function is to cover the gutter or drainage channel to prevent debris and garbage from entering the drainage system, while ensuring the safe passage of vehicles, pedestrians and equipment.
This grate has the characteristics of strong load-bearing capacity, corrosion resistance and long life due to its rectangular design and ductile iron material. It is designed for heavy-load areas and high-flow drainage environments and is suitable for various complex scenarios.
| Dimensions (mm) | Opening Type | Load Class | Application Scope | |
|---|---|---|---|---|
| 500 × 300 | Linear Slots | A15 | Pedestrian paths, parks, greenbelts | |
| 600 × 400 | Mesh Openings | B125 | Non-motorized lanes, residential areas | |
| 700 × 500 | Linear Slots | C250 | Parking lots, urban secondary roads | |
| 800 × 500 | Mesh Openings | D400 | Motorized lanes, main roads | |
| 900 × 600 | Linear Slots | E600 | Industrial zones, ports, docks | |
| 1000 × 500 | Mesh Openings | F900 | Airport runways, heavy industrial zones |
Features:
High strength performance
Made of ductile iron, it has excellent compressive resistance and toughness. Its mechanical properties are close to steel and far superior to gray cast iron.
Particularly suitable for heavy vehicles and high-frequency traffic areas, such as trucks, forklifts, container transportation, etc.
Corrosion resistance
The surface has been treated with anti-corrosion (such as spraying asphalt, epoxy resin), and has good corrosion resistance in harsh environments such as moisture, acid and alkali, and is suitable for long-term outdoor use.
Excellent drainage performance
Scientifically designed opening layout (such as strip, grid, etc.) can effectively improve drainage efficiency and avoid rainwater accumulation.
It can quickly drain water in high-flow environments to prevent water overflow.
High safety
The surface has an anti-slip texture to prevent vehicles and pedestrians from slipping in slippery conditions.
Equipped with anti-theft design (such as special bolts or hinge connections) to prevent the grate from being stolen or displaced and ensure safety.
Rectangular design with strong adaptability
The rectangular shape is easy to seamlessly connect with the drainage ditch, adapting to a variety of scenarios and specifications.
Easy to install and maintain, it can be disassembled separately for cleaning ditches.
Strong load-bearing capacity
The load-bearing level meets international standards (such as EN124 standard). From light load (pedestrian area) to heavy load (industrial area, airport), you can choose the appropriate model according to your needs.
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
