Product OverviewComplies with MD10 (10T load) standards, capable of bearing non-motorized vehicles and small work tool vehicles, well-matching the daily usage needs of small inspection wells;
The reinforced composite structure resists long-term mild pressure, is less likely to crack or deform in inspection well environments, and helps improve the safety of pipe network maintenance operations.
SMC composite material has decent resistance to humid 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 debris, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the problem of traditional cast-iron inspection covers being prone to theft to some extent;
Supports customization of "Chang’an Brand" logo, "检" usage marking, and manufacturer contact email, facilitating ownership management of small facilities.
Cross-patterned anti-slip surface can reduce the risk of pedestrian slipping on rainy days;
Weighing only about 15kg (compared to ~25kg for the same-sized cast-iron cover), it can be installed/maintained by a single person, helping to reduce labor input.

Clean debris from the inspection well opening and confirm the compatibility of the support frame with the 500mm opening;
After fixing the support frame, lay the cover smoothly and fasten the edge buckles;
Conduct a pressure test with a light tool vehicle to confirm the stable fit between the cover and the opening.
Clean debris from the cover surface every 1-2 months to maintain anti-slip texture effectiveness;
Inspect the firmness of buckles every six months (focused verification is recommended after the rainy season);
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 inspection cover products have passed relevant certifications for small municipal facility materials;
Supports customization of "brand + usage marking + contact email" to meet the differentiated needs of small pipe network projects;
Door-to-door delivery is available for bulk orders, and basic installation guidance can be provided for small projects.
