Product Description
FRP Pultruded Grating

Combining corrosion resistance, long life and a low maintenance design, FRP pultruded grating (Fiberglass pultrusion grating) is superior to conventional metallic gratings. This advanced grating is manufactured with a recessed tie bar configuration and is lightweight and easy to fabricate. Manufactured with a high percentage of glass within the laminate, pultruded grating provides durability, extremely high unidirectional strength and stiffness. It can be used with confidence where wide support spans are required, often requiring less additional support than steel counterparts.

Advantages of FRP
FRP Advantages
🚀 Corrosion Resistant

Provides exceptional resistance in the harshest environments and chemical exposures.

🛡️ Slip Resistant

Integrally applied grit surfaces provide unmatched slip resistance for improved safety.

🛠️ Low Maintenance

Eliminates the need for sandblasting or painting. Easily cleaned with high-pressure washers.

🔥 Fire Retardant

Engineered to meet ASTM E-84 flame spread ratings and self-extinguishing requirements.

⚖️ High Strength-to-Weight Ratio

Less than half the weight of steel, allowing for easier installation and removal.

Frequently Asked Questions
What is the difference between I-Type and T-Type pultruded grating?
I-Type grating uses I-shaped bearing bars for standard industrial loads, while T-Type uses T-shaped bars which often provide a larger top surface area, suitable for pedestrian traffic or specific industrial requirements.
Is FRP grating better than steel in corrosive environments?
Yes, FRP is naturally resistant to a wide range of chemicals, acids, and saltwater, meaning it won't rust or corrode like steel, significantly extending the service life.
How does the weight of FRP compare to metal?
FRP pultruded grating is approximately 50-70% lighter than steel grating of the same strength, making it much easier to install without heavy machinery.
Can this grating be used for high-traffic pedestrian areas?
Absolutely. With its slip-resistant grit surface and high unidirectional strength, it is ideal for walkways, bridges, and commercial platforms.
Is the grating UV protected for outdoor use?
Yes, UV inhibitors are integrated into the resin matrix, along with a synthetic surfacing veil, to provide optimum protection against weathering and UV degradation.
What are the fire safety ratings for these products?
Most products are engineered to have a flame spread rating of 25 or less according to ASTM E-84 standards and meet self-extinguishing requirements.
