Elite's 600x600mm SMC Square Manhole Cover is designed for underground utility access, municipal infrastructure, telecommunications, electrical systems, landscaped areas and other engineering applications where corrosion resistance, manageable weight and reliable outdoor performance are required.
Manufactured from glass-fiber-reinforced Sheet Molding Compound (SMC), this square composite access cover is available in A15 and B125 load classes. Its 550x550mm clear opening provides practical access to underground chambers while the molded composite structure supports long-term outdoor use.
The cover is produced from molded SMC reinforced with glass fiber, giving the product a combination of structural strength, toughness, dimensional stability and corrosion resistance.
Compared with conventional rigid cast-metal covers, the composite structure is designed to withstand repeated service conditions while offering lower handling weight and resistance to environmental corrosion.
For projects requiring specific mechanical-property values, fatigue performance or test standards, customers should provide the applicable technical requirements so that the available test documentation for the selected model can be confirmed.
The A15 version of this 600x600mm cover has a listed weight of approximately 17.5 kg, while the B125 version is approximately 25.5 kg.
The lower weight of SMC compared with many traditional cast-metal covers can simplify transportation, positioning, installation and routine access during maintenance.
This is particularly useful for utility projects involving multiple chambers or covers that need to be opened periodically for inspection.
SMC composite does not rust in the same way as conventional ferrous materials. This makes it suitable for outdoor infrastructure exposed to rainwater, humidity, road contaminants and changing environmental conditions.
The molded composite body also reduces dependence on external anti-corrosion coatings, helping maintain material performance in applications where long-term outdoor exposure needs to be considered.
For coastal, chemical, high-humidity or extreme-temperature environments, customers should provide the actual service conditions before ordering so that the material and product configuration can be reviewed accordingly.
The non-metallic SMC structure provides electrical insulation and corrosion resistance, making the product suitable for many electrical, telecommunications and utility applications where a conventional metallic access cover may not be preferred.
This 600x600mm SMC Square Manhole Cover is currently available in A15 and B125 configurations. Both dimensional requirements and required load class should be confirmed before placing an order.
| Code | Load | O | D | F | h | H | Weight |
|---|---|---|---|---|---|---|---|
| SS600A | A15 | 550x550 mm | 600x600 mm | 710x710 mm | 30 mm | 45 mm | 17.5 KG |
| SS600B | B125 | 550x550 mm | 600x600 mm | 710x710 mm | 30 mm | 45 mm | 25.5 KG |
The correct load class should be selected according to the actual installation environment rather than cover dimensions alone.
The SS600A version is listed as A15, while the SS600B version is listed as B125. Customers should confirm the installation zone, expected pedestrian or vehicle loading and applicable project requirements before final selection.
If a higher load class such as C250 or D400 is required, please provide the project specification so that Elite can recommend another suitable product configuration rather than assuming that the A15 or B125 version is suitable.

SMC, or Sheet Molding Compound, is a glass-fiber-reinforced thermoset composite used in applications requiring strength, corrosion resistance, electrical insulation, dimensional stability and molded design flexibility.
Tough composite structure: glass-fiber reinforcement supports mechanical performance and durability.
Corrosion resistance: the composite body does not rust like conventional ferrous materials.
Lower handling weight: can simplify transportation, installation and maintenance.
Electrical insulation: suitable for many electrical and utility access applications.
Low metal value: non-metallic construction can reduce the attraction associated with recyclable metal covers.
Molded flexibility: supports different surface patterns, colors, markings and project-specific designs.
EN124 is widely used as a reference standard for access covers and gratings in infrastructure projects. However, the required load class must match the exact product configuration and installation zone.
This 600x600mm product is currently listed in A15 and B125 versions. Customers requiring EN124 documentation, specific load testing or other conformity information should identify the exact class and documentation requirements before ordering.
Elite provides customized SMC molding solutions in addition to standard manhole-cover sizes. Custom requirements may include dimensions, clear opening, frame design, load performance, surface pattern, molded logo, identification marking, color, locking structure and other project-specific features.
For custom products, customers are encouraged to provide drawings, required dimensions, installation conditions, expected loading, estimated quantity, destination market and required testing or technical documents.

Elite New Materials specializes in SMC and BMC composite products and has more than 20 years of experience in the building materials and composite-products industry.
For manhole covers, material formulation, dimensional consistency, molded structure and finished-product quality directly affect installation and field performance. Elite's quality-control process covers raw material inspection, manufacturing-process control and finished-product inspection.
For projects requiring specific standards, load tests or technical documents, customers should confirm these requirements during the RFQ stage so that the available documentation for the exact product configuration can be reviewed.

Elite supports both standard and customized orders, including international project delivery and batch shipment arrangements.
For customized or urgent projects, lead time depends on dimensions, tooling requirements, quantity and production planning. Customers should confirm the target delivery date during the quotation stage rather than relying on a fixed lead time for every order.
For international shipments, please provide the required quantity, destination country or port, packaging requirements and project schedule so that an appropriate shipping plan can be discussed.
For infrastructure and distribution projects, repeat cooperation, manufacturing quality, technical communication and delivery reliability are important considerations alongside product specifications.
The following customer communication images are retained from the original product page as direct examples of customer feedback.
Elite continues to develop SMC and BMC composite products for infrastructure applications where corrosion resistance, durability and reduced maintenance can contribute to long-term service performance.
The company also participates in community and social-service activities as part of its broader corporate responsibility efforts.

The listed clear opening is 550x550mm. The cover dimension is 600x600mm, while the complete frame dimension is 710x710mm.
Yes. SS600A is listed as A15 and SS600B as B125. The correct version should be selected according to the installation environment and project specification.
The current product specification table lists this model in A15 and B125 configurations. If D400 performance is required, customers should provide the project requirement so that Elite can recommend and confirm a suitable D400 product rather than treating these versions as interchangeable.
EN124 requirements depend on the exact load class and product configuration. Customers requiring EN124 conformity or test documentation should specify the required class and approval documents before ordering so that the available documentation can be confirmed.
SMC combines corrosion resistance, electrical insulation, relatively low weight, molded design flexibility and glass-fiber reinforcement, making it suitable for many utility and infrastructure access applications.
Yes. Depending on engineering feasibility, customization can include dimensions, frame structure, surface design, color, molded logo, markings, locking features and other project-specific requirements.
