Changan’s 800mm round SMC composite manhole cover uses an integral compression-molded structure. It is intended for large inspection well openings in locations such as residential areas, green belts, parks and selected light-vehicle areas. The suitable configuration depends on the installation position and project load requirements.
The current product range lists B125 and C250 configurations. If your project specifies another load class or a different finish, send the requirements for confirmation before the product is selected.
Load Class | Test Load (kN) | Weight | Application Scenarios |
|---|---|---|---|
B125 | 125 | 89 kg | Large‑opening municipal pedestrian inspection wells, residential main inspection wells, green‑belt utility wells, park large‑caliber access wells, only for pedestrian & non‑motor‑vehicle traffic |
C250 | 250 | 108 kg | Large‑caliber manholes in residential internal driveways, light‑duty parking lots, within 0.5 m of kerbs, occasional light‑vehicle passing areas |
Select the load class according to the actual installation position and the project’s applicable requirements. Confirm the cover and frame dimensions, configuration and product weight on the final drawing or quotation.
SMC composite construction: Glass fiber reinforced Sheet Molding Compound formed by compression molding.
Two published configurations: B125 and C250 versions are listed for different installation conditions.
Optional anti-theft lock: Discuss the locking requirement when requesting a quotation.
Custom appearance: Surface pattern and color options can be discussed for the project.
Size discussion: For an existing well, provide the clear opening and frame dimensions so the fit can be checked.
For an accurate recommendation, provide the installation location, clear opening size, frame dimensions, required load class and expected traffic. If you need a lock, a particular surface pattern or a project color, include those requirements with your drawing.

The published configurations are B125, with a 125 kN test load, and C250, with a 250 kN test load. Select the configuration according to the installation position and project requirements.
The product page describes the C250 configuration for certain internal driveways, light-duty parking areas and occasional light-vehicle passage. Confirm the actual traffic conditions and required class before ordering.
The current product information lists an optional anti-theft lock, surface pattern and color. Include your requirements in the inquiry so availability can be confirmed.
Send the well opening and frame dimensions, installation location, required load class, quantity and any customization requirements. A drawing or photo of the existing opening will help confirm the fit.
