Product OverviewComplies with common load standards (recommended ≤10T), capable of bearing water supply work vehicles and light vehicles, well-matching the daily operation and maintenance needs of water supply inspection wells;
The reinforced composite structure is less likely to crack or deform in humid environments, helping to improve the safety of water supply network maintenance operations.
SMC composite material has decent resistance to humidity in water supply environments, and its service life is expected to reach 20 years or more under proper use;
The dense surface material is not easy to attach scale or debris, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the problem of traditional cast-iron water supply covers being prone to theft to some extent;
Supports customization of regional water supply logos (e.g., "Linyi Water Supply"), "Water Supply" usage labels, and contact emails, facilitating ownership and operation management of water supply facilities.
Cross-patterned anti-slip surface can reduce the risk of slipping for workers on rainy days;
Weighing about 20kg (compared to ~35kg for the same-sized cast-iron cover), it can be installed/maintained by a single person, helping to reduce labor input in water supply operation and maintenance.

Clean debris from the water supply inspection well opening and confirm the compatibility of the support frame with the 600mm opening;
After fixing the support frame, lay the cover smoothly and fasten the edge buckles;
Conduct a pressure test with a light work vehicle to confirm the stable fit between the cover and the opening.
Clean scale and debris from the cover surface monthly to maintain anti-slip texture effectiveness;
Inspect the firmness of buckles quarterly (focused verification is recommended after water supply peak seasons);
No additional anti-corrosion treatment is required. If damage occurs, 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 supply inspection cover products have passed relevant certifications for municipal water supply facility materials;
Supports customization of regional water supply logos, usage labels, and contact information to meet the differentiated needs of local water supply projects;
Door-to-door delivery is available for bulk orders, and operation and maintenance installation guidance can be provided for water supply projects.
