Engineered for strength and safety, our FRP manhole covers are ideal for municipal and industrial use. Lightweight, corrosion-resistant, and built to perform.
FRP manhole cover is a composite access solution made from high-strength fiberglass and polymer resin. Designed for long-term performance, it offers excellent load capacity, superior corrosion resistance, and enhanced safety. Ideal for urban infrastructure, utilities, and industrial environments.
Product Advantages and Features:
High Load Capacity: Rated A15–D400 for traffic and utility use.
Lightweight Design: 70% lighter than metal, easy to install. Safe & Non-Conductive: Insulating, non-slip, and non-magnetic. Corrosion Resistant: Withstands moisture, salt, and chemicals. Zero Theft Risk: No scrap value, long service life, low upkeep.
Application Scenarios:
Urban Infrastructure: Roadway access points, sidewalks, and utility vaults in cities and municipalities.. Power & Telecom Systems: Ideal for areas requiring non-conductive materials around cables, switchgear, or fiber optics. Sewage & Drainage: Resistant to wastewater and harsh chemicals—used in manholes for sewer and stormwater systems.
Industrial Facilities: Deployed in factories, chemical plants, and storage zones for reliable access over corrosive environments.
