Product Description
Fiberglass manhole covers are mainly made of unsaturated resin as the main raw materialand are compositely modified with a variety of materials. After molding, they not only havehigh strength and beautiful appearance, but also have good electrical insulation propertieswaterproof, aging resistance, acid and alkali resistance, high strength. lt has thecharacteristics of good anti-corrosion performance, impact resistance, wear resistanceresistance to sun and rain, anti-static, and anti-theft. lt is an ideal substitute for traditionalmetalmanhole 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.
