Frequently Asked Questions

Q: What does the D400 load class signify in metal manhole covers?

D400 denotes a load class suitable for areas where road traffic may occur, such as carriageways of roads, hard shoulders, and parking areas, supporting heavy-duty vehicular loads.

Q: How does the GRP sealing plate improve the manhole cover?

The 7mm reinforced Glass Reinforced Plastic (GRP) plate provides a gas-tight and water-tight barrier, preventing pollutants or water from entering the access opening.

Q: Can the cover be removed without the hinge?

Yes, the design allows the cover to be removed without disassembling the hinge, providing flexibility for maintenance and replacement.

Q: Is the locking system resistant to corrosion?

Absolutely. The closing system and key are manufactured from high-grade stainless steel to ensure durability in harsh outdoor environments.

Q: What is the purpose of the EPDM gasket in this system?

The continuous EPDM O-ring increases stability, eliminates rocking during traffic flow, and significantly reduces operational noise.

Q: Does this product offer OEM customization for different sizes?

Yes, we provide comprehensive OEM services for the metal products industry, allowing for custom dimensions and material specifications to meet specific project needs.
