FRP gratings are commonly molded using high-strength fiberglass reinforcement materials along with resin and other additive agents to enhance product quality. Molded FRP gratings find widespread use across various industrial sectors such as power generation, waste processing, oil refining, mining, and more. Additionally, these gratings are increasingly utilized in commercial settings as interior and exterior materials, including drainage systems, fencing, building facades, ceilings, and others.
In addition to standard sizes, we also offer custom-sized gratings. In Indonesia, grating products have the most extensive variations in mesh sizes including 38×38, 50×50, rectangular mesh 100×25, rectangular mesh 152×38, mini mesh 20×20, micro mesh 13×13, and with variable heights ranging from H25, H30, H38, to 50. Available surface finishes include concave, anti-skid, chequer plate, and flat.
Advantages of FRP Grating
FRP grating, whether formed through molding or pultrusion processes, offers significant benefits in various industrial and commercial applications. The high strength of fiberglass and its corrosion resistance make it ideal for harsh environments such as power plants, mining areas, and oil refineries. Additionally, its lightweight nature facilitates easy mobilization, installation, and maintenance, while the anti-slip surface ensures user safety. Another advantage is its ability to be produced in various sizes and designs according to needs, enhancing its usage flexibility. With a combination of strength, durability, and flexibility, FRP grating becomes a reliable and efficient choice for various structural needs in industrial and commercial sectors.
Orindo Eratec provides two types of fiberglass grating (FRP): FRP Molded Grating and FRP Pultruded Grating.
FRP Molded Grating is a material that combines fiberglass with resin, pigments, and other additives into a mold, resulting in grating products with the size of the mold panel used. This FRP Molded Grating is lightweight, corrosion-resistant, and able to withstand harsh environmental conditions. With precisely formed grating, FRP Molded Grating offers high structural strength and anti-slip properties, making it an ideal choice for various industrial and commercial applications.
FRP Pultruded Grating is a type of grating made through an assembling process produced by a pultrusion machine, where fiberglass, resin, pigments, and other additives are mixed in a vat and then pulled through a mold to form strong and rigid profiles. This material offers high strength, dimensional stability, and resistance to corrosion and harsh environmental conditions. Its robust and precise design makes FRP Pultruded Grating a superior choice for industrial applications requiring high durability and performance.
Pultruded Grating and Molded Grating are two common types of grating used in various industrial applications. Here is a comparison between them:
- Material Composition:
- Pultruded Grating: Fiberglass (roving and mat), Resin, Pigments, Additives. Fiberglass percentage: 70%, Resin Mix: 30%
- Molded Grating: Fiberglass (roving), Resin, Pigments, Additives. Fiberglass percentage: 40%, Resin Mix: 60%
- Production Process:
- Pultruded Grating: Produced through an assembling process from products generated by a pultrusion machine. Fibers, resin, pigments, and other additives are mixed in a vat and then pulled through a mold to form strong and rigid profiles.
- Molded Grating: Produced by combining fiberglass with resin, pigments, and other additives into a mold. This results in grating products with the size of the mold panel used. FRP Molded Grating is lightweight, corrosion-resistant, and able to withstand harsh environmental conditions.
- Production Capacity:
- Production capacity depends on the facilities and equipment used. We can adjust production capacity according to customer demand.
- Price:
- Prices for Pultruded Grating and Molded Grating can vary depending on size, thickness, material, and other additional specifications. Generally, Molded Grating might be cheaper than Pultruded Grating due to a simpler production process, but this can vary depending on other factors.
- Strength Difference:
- Pultruded Grating generally has higher strength than Molded Grating due to the production process leading to more consistent fiber orientation and even resin distribution. Therefore, Pultruded Grating is often used in applications requiring high strength or heavy loads. However, for chemical resistance, Molded Grating is stronger because its resin content is higher than that of pultruded grating.
The choice between Pultruded Grating and Molded Grating will depend on specific application needs, budget, and the preferences of the manufacturer or end user.
