Fiberglass Grating / FRP Grating

Fiberglass grating is mainly composed of high-quality resins such as unsaturated polyester resin (UPR), vinyl resin (VE), epoxy resin (EP), etc., which are compounded with glass fibers (E glass fiber or C glass fiber). This material combination endows the fiberglass grating with lightweight, high-strength, and corrosion-resistant. Resin as the matrix material, has good adhesion and chemical stability, glass fiber provides excellent tensile strength and bending strength, making the fiberglass grating stable even under heavy loads. Resin ensures the durability and reliability of the product. The addition of fiberglass significantly improves the mechanical properties of the material, allowing the fiberglass grating to maintain excellent performance even under harsh conditions. Compared to steel grating,fiberglass grating is considerably lighter. These characteristics mean our fibreglass grating is easy to install in challenging areas, saving you installation time, labour and transportation costs. In addition, because fiberglass grating is very durable and non-corrosive, long-term performance is a given in aggressive environments where metallic options fail over time.

Mainstream Process Manufacturing

Molded Fiberglass Grating & FRP Grating

Molded FRP Grating is a fiberglass reinforcement plastic grating by interweaving continuous fiberglass roving impregnated with unsaturated polyester resin.Molded fiberglass grating is chemical resistant, strong, lightweight, and non-sparking. It is available in square or rectangular mesh

Flat grating

Integrally Applied Grit Top

Concave grating / Meniscus Top

Diamond FRP

Microvoid Grating

Pultruded Fiberglass Grating (FRP)

Pultruded FRP grating is made up of pultruded shape “I” or “T”. Using solid rods as jointing to assemble into panels with many meshes.
Pultruded Fiberglass Grating is the ideal solution for platforms, ramps, stairs, and more. This grating is slip-resistant, non-conductive, strong, lightweight, and corrosive resistant which makes it ideal for many industries.

FIBERGALSS GRATING ADVANTAGES

Corrosion and Aging Resistance
+

Excellent corrosion resistance, which can resist chemical media such as acid, alkali, organic solvents, and salts. It will not rust or degrade due to long-term contact with corrosive substances, and can maintain stable performance under UV radiation, humid and hot environments, and cold conditions.
Excellent Anti Slip Performance
+

The surface can be designed as a concave surface, anti slip sand layer, or covered with anti slip plates, which can effectively improve friction and reduce slip accidents.
Low Density, High Strength
+

The material density is low, only 1/4 of traditional steel, but its strength is comparable to steel and can meet the load-bearing requirements. No need for large lifting equipment during installation, reducing construction costs
Electrical Insulation and Flame Retardancy
+

Non conductive, non thermally conductive, safer to use in high humidity environments or live working scenarios Made of flame-retardant resin has a certain degree of flame retardancy, with an oxygen index of 26 or higher, meeting various fire safety requirements

FAQs for FRP Fiberglass Grating

1. What is FRP grating and where is it commonly used?

FRP (Fiberglass Reinforced Plastic) grating is a lightweight, high-strength composite material made of fiberglass and resin. It features anti-corrosion, anti-slip, flame-retardant and low-maintenance properties, widely applied in chemical plants, sewage treatment, marine platforms, power stations, walkway flooring, trench covers and industrial anti-corrosion platforms.
2. What is the difference between molded FRP grating and pultruded FRP grating?

Molded FRP grating adopts one-piece integral molding, with uniform force, excellent chemical resistance and impact resistance, suitable for general walkway and anti-corrosion environments. Pultruded FRP grating has higher longitudinal strength and lighter weight, ideal for long-span, high-load industrial platforms and heavy-duty working conditions.
3. Why choose FRP grating instead of traditional steel grating?

Compared with steel grating, FRP grating never rusts and requires no painting or galvanizing maintenance. It is 70% lighter in weight, easier to transport and install, and provides better anti-slip and insulation performance. Its long service life effectively reduces long-term replacement and maintenance costs for industrial projects.
4. Is FRP grating anti-corrosive and chemical resistant?

Yes. FRP grating is inherently resistant to acid, alkali, salt water and most chemical solutions. By adopting different resin systems including polyester, vinyl ester and epoxy, it can adapt to harsh corrosive environments such as marine, sewage and chemical workshops without oxidation or corrosion.
5. Does FRP grating have anti-slip performance?

All standard FRP gratings are designed with integrated anti-slip gritted surfaces or concave anti-slip structures. It effectively prevents slipping in wet, oily and dusty working conditions and fully meets industrial safety and OSHA walking standards.
6. Is FRP grating flame retardant and safe for fire prevention?

Yes. We provide Class 1 flame-retardant FRP grating with low flame spread and low smoke density, complying with ASTM E84 industrial fire standards. It can effectively inhibit flame spreading and ensure safety requirements for factory and public facility applications.
7. What temperature range can FRP grating withstand?

High-quality FRP grating maintains stable mechanical performance within the temperature range of -40°C to +120°C. It will not become brittle in low-temperature environments or deform and soften under normal high-temperature working conditions, adapting to seasonal temperature changes in most regions.
8. How long is the service life of FRP grating?

Standard industrial-grade FRP grating lasts 12–15 years, while marine-grade and high chemical-resistant grades can reach more than 20 years. Featuring UV stabilization and aging resistance, it avoids frequent replacement caused by rust, corrosion and weathering like metal materials.
9. Is FRP grating easy to install and maintain?

FRP grating is lightweight and easy to cut on site, requiring no welding or complex construction. It is fixed with matched stainless steel clips and bolts for fast installation. Daily maintenance is almost unnecessary, only simple water cleaning is needed to keep the surface clean.
10. Can you provide customized FRP grating?

Yes. Jinnuo Metal supports full customization of mesh size, thickness, panel size, color, surface anti-slip treatment and special resin formulas. We can produce non-standard FRP gratings and finished stair treads, trench covers and platform accessories according to customer drawings and site working conditions.
11. Does FRP grating have insulation properties?

Yes. FRP is a non-conductive composite material with excellent electrical insulation performance. It is safe and reliable for power plants, electrical workshops and high-voltage equipment platforms, effectively avoiding electric leakage and electric shock risks.
