Product OverviewRecommended load ≤8T, capable of bearing pedestrians and small work vehicles, well-matching the dual needs of water meter well operation and drainage;
Rectangular drainage hole design improves drainage efficiency, helping reduce water accumulation around water meter wells while facilitating water meter maintenance.
SMC composite material has decent resistance to erosion in humid environments, with an expected service life of over 18 years under proper use;
The surface material is not easy to adhere to sludge, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron water grate & water meter covers to some extent;
Integrates water grate and water meter inspection functions, eliminating the need for additional drainage facilities and simplifying scenario supporting.
Weighing about 22kg (vs. ~40kg for the same-sized cast-iron product), it can be installed/maintained by a single person, helping reduce operation labor costs.

Clean debris from the water meter well opening and confirm the support frame’s compatibility with the opening;
Align the drainage holes (preferably toward the water accumulation side), lay the cover, and fasten the buckles;
Conduct a light pressure test to confirm the cover’s stable fit.
Clean debris from drainage holes every 2 weeks to keep drainage unobstructed;
Inspect buckle firmness every 6 months (focused verification is recommended after the rainy season);
No additional anti-corrosion treatment is required. If damaged, send an email to jschangan111@gmail.com to contact the manufacturer for replacement coordination.
With over 10 years of experience in composite manhole cover production, its water grate products have passed relevant certifications for municipal small facility materials;
Supports customization of sizes and drainage hole layouts to meet different water meter well scenario needs;
Door-to-door delivery is available for bulk orders, with supporting basic installation guidance.
