Molded FRP / GRP grating is made of continuous fiberglass roving, fully soaked by unsaturated polyester resin with continuous solidification through Molding process.
It offers various property of corrosion resistance and durability of types of fiberglass gratings due to different resins.
| Resin Base | Orthophthalic (GP) | Isophthalic (ISO) | Vinyl Ester (VE) |
| Description |
Mostly used for general purpose. Its low cost makes it popular in many outdoor general applications and in moderate corrosive environments. |
Premium grade polyester resin which provides good chemical resistance with high physical properties. | Extremely corrosion resistance and fire retardant. |
| Application | Such as walkways, drain covers, and irrigation applications, providing protection against corrosion compared to traditional metal gratings. | Such gratings can be used in the environments of middle concentration inorganic acid, inorganic alkali, etc. |
Suitable for severe corrosion applications requiring better assistance to alkaline and acidic environments. Such gratings can be used in the environments with serious corrosion. |
