Composite D400 Gully Pot Grating 360 x 510mm 40 Ton

Gully Pot Grating

The Composite D400 Gully Pot Grating provides a high-strength drainage solution for civil engineering and infrastructure projects. This D400 rated component withstands heavy vehicular traffic in demanding environments. It fits standard gully pots used in municipal and industrial surface water management systems.

Built for the Job

Site supervisors and civil contractors select this drainage cover for areas requiring high load-bearing capacity without the weight of traditional iron. It serves as a primary intake point for surface runoff in parking lots, commercial loading bays, and secondary roads. The fiber-reinforced polymer construction ensures the unit remains stable under constant vibration from passing vehicles. Because the material has no resale value as scrap, it effectively eliminates the risk of theft on public sites. This helps facility managers maintain safety standards without frequent replacement costs.

• Installation in commercial parking zones and industrial estate access roads.

• Replacement of stolen or damaged cast iron gratings in high-theft areas.

• New builds requiring corrosion-resistant surface water drainage.

Product Highlights

On-Site & Workshop Notes

• Always bed the frame in a high-strength M4 mortar or resin-based bedding compound.

• Ensure the grating sits flush with the surrounding asphalt or concrete to prevent trip hazards.

• Clean the seating area regularly to prevent debris buildup that might cause the lid to rock.

• The lightweight nature of this material allows for easier manual handling compared to iron units.
