Product OverviewRecommended load ≤5T, capable of bearing pedestrians and mini rainwater maintenance tools, well-matching the daily operation and mild traffic needs of mini rainwater wells;
The reinforced composite structure is not prone to cracking or deformation in rainwater well environments, helping to improve the safety of mini maintenance operations.
SMC composite material has strong erosion resistance in humid, mild-corrosion mini rainwater well environments, with an expected service life of over 18 years under proper use;
The anti-slip surface texture is not easy to accumulate 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 mini inspection covers to some extent;
Dual handle holes are adapted to the weight of mini-sized covers, allowing easy opening by one person and improving mini rainwater well maintenance efficiency.
Weighing about 10kg (vs. ~20kg for the same-sized cast-iron product), it is more convenient to install and carry, reducing labor input for mini cover operations.

Clean debris from the mini rainwater well opening and confirm the size compatibility of the support frame with the opening;
After fixing the support frame, lay the cover smoothly aligned with the handle hole direction and fasten the edge buckles;
Conduct a light pressure test to confirm the cover’s fitting stability.
Clean surface sludge monthly to maintain anti-slip texture effectiveness;
Inspect the firmness of handle holes and buckles 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 mini composite cover production, its rainwater inspection covers have passed relevant certifications for municipal micro facility materials;
Supports customization of sizes and logos to meet different mini rainwater well scenario needs;
Delivery service + exclusive installation guidance for mini scenarios are available for bulk orders.
