Behold the marvel of FRP manhole covers, crafted meticulously from glass fiber and its derivatives-such as glassfiber cloth and felt-as the reinforcing backbone, paired elegantly with synthetic resins like unsaturated polyester and epoxy. These covers are born through meticulously executed molding processes, including compression and hand lay-up techniques, ensuring a blend of strength and aesthetic allure.
Our fiberglass manhole covers are a testament to engineering excellence, primarily utilizing unsaturated resin enhanced by a blend of superior materials. The resultant covers exhibit not only high tensile strength and an attractive visage but also exceptional electrical insulation, waterproof properties, and remarkable resistance to aging and corrosive elements. Embrace a product that offers unparalleled anti-corrosion, impact resilience, wear resistance, and protection against the elements, boasting anti-static and anti-theft features. This makes them the quintessential replacement for conventional metal manhole covers.

2. What's FRP?
Fiber Reinforced Polymer (FRP) is a composite material made of a polymer matrix reinforced with fibers. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper or wood or asbestos have been used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and formaldehyde resins are still in use. FRP are commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.
