Fiber reinforced polyester (FRP) is the next generation polymer made of a polymer matrix reinforced with fibers. These polymers are considered to be the strongest one and most resistive to deforming forces. With the advancements, FRP has totally replaced traditional materials like RCC, CI and steel for manufacturing manhole covers, gratings, doors, window shades and security cabins.
| RCC | CI | FRP | |
| Life Span | Low | Moderate | High |
| Strength/Weight Ratio | Very Low | Moderate | Very High |
| Cost | Low | Moderate | Comparable to CI |
| Scrap Value | Low | High | Nil (Zero Scrap Value) |
| Color Range | Concrete Grey | Black / Metallic | Range Available |
| Finishing | Not Applicable | Rough | Granite Finish |
| Logo Embossing | Not Available | Not Available | Possible |
| Custom Design | Not Available | Not Available | Possible |
| Locking System | None | None | Available |
| Handling | Very Difficult | Difficult | Easy |
| Thermal Expansion | Slight | High | Almost Nil |
| Corrosion Resistance | Low | Medium | High |
| Abrasion Resistance | None | None | Yes |
| Properties | FRP | Steel |
| Corrosion Resistance | Very High | Subjected to Oxidation & Corrosion |
| Weight | Light Weight | require lifting equipments to move and place |
| Conductivity | Highly insulating material | Conducts electricity, potential Shock hazard |
| Strength | High strength to weight ratio | Lower strength to weight ration |
| Stiffness | Will not permanently deform under load conditions | Any deformation will be permanent in nature |
| Impact Resistance | Glass mat distributes load evenly to prevent surface damage | Can permanently deform under impact |
| EMI / RFI Transparency | Transparent to EMI/RFI interferences | Can Interfere with EMI/RFI transmissions |
| Versatility | Pigments added to resin provide uniform coloring through volume | Color is applied only on surface via paint or coating |
| Field Fabrication | Can be fabricated on site using simple carpenter tools. Erection easy due to light weight | Needs specialized cutting and welding equipment and skilled labor Heavier material requires special lifting equipments to manage. |
| Cost | Lower life cycle cost due to low maintenance and installation cost | High life cycle costs |
