Excellent quality for municipal projects
We ordered these double lid grates for a city renewal project. The ductile iron quality is top-notch, and the bitumen coating provides great corrosion resistance. Delivery was faster than expected.

Solid construction, heavy duty
These covers are very heavy and robust, perfect for our industrial driveway. The hinged double lid makes maintenance access much easier. Only minor issue was the shipping cost due to weight.

Perfect fit and finish
Ordered standard sizes and they fit perfectly into our pre-cast concrete channels. The anti-theft locking mechanism gives us peace of mind in public areas.
Q: Is the bitumen coating sufficient for coastal areas with high salinity?
A: While bitumen offers good protection, for highly corrosive coastal environments, we recommend upgrading to hot-dip galvanized treatment for extended longevity.
Q: What is the lead time for a container load of mixed sizes?
A: For a full container load with mixed specifications, the typical production and preparation time is 10 to 12 days after order confirmation.
Q: Do these grates come with the hinges and locking pins included?
A: Yes, all double lid systems come complete with heavy-duty stainless steel hinges and locking pins ready for installation.
Q: Can you manufacture custom sizes if our trench dimensions are non-standard?
A: Absolutely. We offer customization services for both length and width. Please provide your specific drawings or dimensions for a quote.
Q: What is the maximum load capacity for the D400 class?
A: Class D400 indicates a test load of 400 kN (approximately 40 tons), making it suitable for carriageways and hard shoulders of highways.
