Elite's 650x850mm SMC Square Manhole Cover is designed for underground utility access, municipal infrastructure, telecommunications, electrical systems, landscaping facilities, drainage systems and other engineering applications where corrosion resistance, manageable handling weight and dependable access performance are required.
Manufactured from glass-fiber-reinforced Sheet Molding Compound (SMC), this rectangular composite access cover is available in A15 and B125 load classes. Its 600x800mm clear opening provides practical access for utility chambers, while the molded composite structure supports durable outdoor use.
The cover is manufactured from molded SMC composite reinforced with glass fiber. This structure combines mechanical performance, corrosion resistance and lower handling weight than many conventional cast-metal covers of comparable size.
The current 650x850mm model is available in A15 and B125 configurations. The correct version should be selected according to the installation zone, expected loading conditions and applicable project requirements.
Utility access covers may experience repeated loading, vibration and impact throughout their service life. The molded composite structure and cover-frame design help distribute applied loads while reducing the rigid metal-to-metal impact associated with some traditional access cover systems.
This makes the product suitable for infrastructure locations where repeated pedestrian or light-traffic loading, regular maintenance access and long-term service durability need to be considered together.
For projects with specific fatigue, impact or dynamic-load requirements, customers should provide the applicable technical criteria or engineering standard during the RFQ stage so that the required product configuration can be reviewed.
This 650x850mm model has a listed weight of approximately 43.0 kg. Compared with many heavy cast-metal alternatives, SMC composite construction can simplify transportation, positioning, installation and routine maintenance.
For projects involving multiple chambers or covers that require periodic inspection, reduced handling weight can also help improve installation and maintenance efficiency.
SMC composite does not rust in the same way as conventional ferrous materials. This makes the cover suitable for municipal, utility, drainage and outdoor infrastructure applications exposed to rainwater, humidity and changing environmental conditions.
For coastal, industrial, chemical or other demanding environments, customers are encouraged to provide the actual operating conditions before ordering so that the material and product configuration can be reviewed accordingly.
The 650x850mm SMC Square Manhole Cover is currently listed in A15 and B125 versions. Both dimensional requirements and load class should be confirmed before placing an order.
| Code | Load | O | D | F | h | H | Weight |
|---|---|---|---|---|---|---|---|
| SS650x850A | A15 | 600x800 mm | 650x850 mm | 745x945 mm | 30 mm | 50 mm | 43.0 KG |
| SS650x850B | B125 | 600x800 mm | 650x850 mm | 745x945 mm | 30 mm | 50 mm | 43.0 KG |
Load class selection should be based on the actual installation environment rather than cover dimensions alone.
The SS650x850A version is listed as A15, while the SS650x850B version is listed as B125. If the required load class is not clearly specified in the project drawings, customers should provide the installation location, expected traffic conditions and applicable engineering requirements before final selection.

SMC, or Sheet Molding Compound, is a glass-fiber-reinforced thermoset composite used where strength, corrosion resistance, electrical insulation, dimensional stability and molded design flexibility are important.
Corrosion resistance: the composite body does not rust like conventional ferrous materials.
Lower handling weight: helps simplify transportation, installation and maintenance.
Electrical insulation: suitable for many electrical and utility environments where a non-metallic cover is preferred.
Low metal value: the non-metallic construction can reduce the attraction associated with recyclable metal covers.
Molded flexibility: surface patterns, markings, colors and other features can be incorporated according to project requirements.
In addition to standard sizes, Elite provides customized SMC molding solutions for infrastructure and industrial projects. Custom requirements may include cover dimensions, clear opening size, frame design, load performance, surface pattern, molded logo, identification marking, color, locking structure and other application-specific features.
For custom projects, customers are encouraged to provide drawings, required dimensions, installation conditions, expected loading, estimated quantity, destination market and required technical documentation.
