FRP utility infrastructure systems include fiberglass light poles, manhole covers, and acoustic barriers for infrastructure, utility-related, and environmental applications. This page provides an overview of these product types and the main factors used to evaluate their material, mechanical, electrical, environmental, and installation requirements.
FRP Utility Infrastructure Systems
FRP utility infrastructure products include fiberglass light poles, manhole covers, and acoustic barriers. These product types can be used in public, industrial, and utility-related infrastructure where material selection depends on application, loading, environmental exposure, electrical requirements, and installation conditions.
Selection Considerations
- Mechanical requirements – consider load requirements, support conditions, wind exposure, and installation configuration.
- Electrical considerations – for applicable products, review electrical insulation requirements and the requirements of the intended system.
- Environmental exposure – consider UV exposure, moisture, salt spray, chemicals, and other site-specific conditions.
- Load classification – for applicable manhole covers, select the required load class according to the intended traffic and installation conditions.
- Acoustic requirements – for sound barrier applications, consider the required barrier configuration, installation environment, and acoustic design objectives.
- Applicable references – standards and project specifications should be reviewed where they apply to the selected product and installation conditions.
Frequently Asked Questions
How is the load class of an FRP manhole cover selected?
The required load class depends on the intended traffic, installation location, support conditions, and applicable project requirements. Where a specific standard is referenced, such as EN 124, the applicable load classification should be verified for the selected configuration.
Are FRP light poles electrically conductive?
FRP is generally electrically non-conductive, but electrical and grounding requirements depend on the complete installation and the applicable project or utility requirements. The electrical design should therefore be evaluated for the specific application.
