Why Choose ductile iron grating?
THE product are commonly used in road drainage projects where the grating needs to support traffic loads and collect surface water from roads, parking areas, and municipal drainage systems.
Compared with light-duty drainage grates, a D400 ductile iron gully grating is more suitable for areas where higher load capacity, stable frame installation, and durable outdoor performance are required. The combination of ductile iron material, open slot drainage design, and grating-frame structure makes this product a practical choice for infrastructure projects.

FAQ
What is a road drainage grate?
A D400 gully grating is a drainage grating designed for areas where higher load capacity is required, such as roads, parking areas, and municipal drainage systems. It is commonly used for surface water collection and stormwater drainage.
Where can D400 ductile iron gully gratings be used?
They can be used in urban roads, parking lots, sidewalks, stormwater drainage channels, commercial areas, and municipal infrastructure projects.
What is the difference between a gully grating and a manhole cover?
A gully grating is designed with open slots to collect surface water, while a manhole cover is usually used to close access points for sewer, drainage, or utility systems.
How do I choose the right gully grating for road drainage?
When choosing a gully grating for road drainage, buyers should consider the required load class, grating dimensions, frame design, drainage capacity, installation location, and project drawings. For roads and parking areas, D400 ductile iron gully gratings are commonly used where higher load capacity is required.
Can road gully gratings be removed for maintenance?
Yes. Many road gully grating designs allow removal for cleaning, inspection, and stormwater drainage maintenance. The removal method depends on the grating design, frame structure, product weight, installation condition, and site access.
For heavy-duty road drainage applications, removal should be handled by trained maintenance teams using suitable lifting tools and the correct site safety procedures. The grating should be removed in accordance with the project maintenance requirements and the approved lifting method.
Before ordering a ductile iron gully grating, buyers should confirm the grating’s weight, lifting access, frame design, maintenance frequency, and site safety requirements. If frequent cleaning or inspection is required, this information should be shared before quotation or production so a suitable grating and frame design can be recommended.
Can the size and frame design be customized?
Yes. Hongke can customize the size, frame design, slot pattern, coating, marking, logo, and packaging according to drawings and project requirements.
Is this product also called a cast iron gully grating?
Some buyers may use the term cast iron gully grating when searching for drainage grates. This product is made from ductile iron, which provides better strength and durability for road drainage applications.
