Product OverviewRecommended load ≤10T, capable of bearing light work vehicles and maintenance tool vehicles, well-matching the daily operation and mild traffic needs of medium-sized inspection wells;
The reinforced composite structure is not prone to cracking or deformation in inspection well environments, helping to improve the safety of maintenance operations.
SMC composite material has decent erosion resistance in humid, mild-corrosion inspection well environments, with an expected service life of over 18 years under proper use;
The anti-slip surface texture is not easy to accumulate dirt, making daily cleaning and maintenance relatively convenient.
Non-metallic material has no recycling value, which can alleviate the theft issue of traditional cast-iron square inspection covers to some extent;
Dual handle holes are adapted to the weight of medium-sized covers, allowing easy opening by one person and improving inspection well maintenance efficiency.
Weighing about 22kg (vs. ~40kg for the same-sized cast-iron product), it is more convenient to install and carry, reducing labor input for medium-sized cover operations.

Clean debris from the inspection 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 to ensure it fits the opening edge;
Conduct a light pressure test with a light tool vehicle to confirm the cover’s fitting stability.
Clean surface stains monthly to maintain anti-slip texture effectiveness;
Inspect the firmness of handle holes and buckles quarterly (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 medium-sized composite cover production, its square inspection covers have passed relevant certifications for municipal facility materials;
Supports customization of sizes, surface textures, and logos to meet different medium-sized inspection well scenario needs;
Delivery service + basic installation guidance are available for bulk orders, ensuring the operation efficiency of medium-sized covers.
