Material

Ductile Iron Construction

Our drainage grates are manufactured primarily from ductile iron, which is widely used for road and drainage infrastructure because of its combination of strength, toughness, and durability.

Ductile iron provides good resistance to impact and repeated loading, making it suitable for outdoor drainage applications exposed to pedestrians and vehicles.

Material Advantages

• High mechanical strength
• Good impact resistance
• Strong load-bearing capability
• Durable outdoor performance
• Suitable for repeated traffic loads
• Good structural stability
• Suitable for casting complex designs

Material grades and mechanical requirements can be specified according to customer drawings, applicable standards, and project requirements.

Technical Parameters

Product Features

Anti-Slip Surface

Raised surface patterns can improve traction and provide a more stable surface when exposed to rainwater or wet conditions.

Efficient Drainage

The grate opening design allows surface water to enter the drainage system while maintaining a practical surface for pedestrians and vehicles.

Stable Frame Support

The supporting frame provides a stable seating area for the grate and helps transfer loads to the surrounding drainage structure.

Hinged Connection

The hinged design keeps the grate connected to the frame during opening and maintenance, making inspection and cleaning more convenient.

Durable Ductile Iron

The ductile iron construction provides strength and durability for demanding outdoor and infrastructure applications.

Application Scenarios

Road Drainage

Used along urban roads and streets to collect rainwater and surface runoff.

Stormwater Systems

Suitable for stormwater collection points, drainage channels, and municipal water management systems.

Sidewalks & Pedestrian Areas

Suitable for sidewalks, plazas, pedestrian areas, and public spaces requiring surface drainage.

Parking Areas

Used in residential and commercial parking lots for surface water collection.

Municipal Infrastructure

Suitable for urban drainage systems, municipal roads, public facilities, and infrastructure projects.

Industrial Facilities

Can be used in factories, warehouses, logistics centers, industrial parks, and other areas requiring durable drainage solutions.

How to Choose the Right Drainage Grate?

When selecting a ductile iron drainage grate, consider:

Installation Location

Determine whether the grate will be installed in a pedestrian area, parking lot, road, industrial facility, or other vehicle-accessible location.

Size

Confirm the drainage opening and required frame dimensions.

Load Rating

Select the appropriate structural configuration according to expected pedestrian and vehicle loads.

Drainage Capacity

Consider the required water flow and drainage opening design.

Grate Type

Choose between:

• Round Stormwater Drainage Grate
• Square Single-Piece Drainage Grate
• Hinged Drainage Grate

Maintenance Requirements

For locations requiring frequent inspection and cleaning, a hinged drainage grate can provide more convenient access.
