Surface & Fire
Gritted Top
R13 friction coefficient under EN 14122 — maximum slip resistance for wet and oily conditions. In wet/oily conditions, gritted surface improves friction coefficient by 40%.
Concave/Meniscus Top
Moderate slip resistance — ideal for general industrial applications where drainage is a consideration.
Smooth Top
Easy cleaning surface — perfect for food processing, pharmaceutical, and hygiene-critical environments.
Fire & Electrical Performance
- Phenolic gratings: Certified to ASTM E84 Class A — suitable for airports, offshore facilities, high-risk environments
- Electrical Insulation: Non-conductive with resistivity > 10⁹ Ω·cm — ideal for electrical substations and cable trenches
Core Advantages
Key Features of FRP Grating
Hengchen's FRP grating stands out in the global market with these core characteristics:
Lightweight & High-Strength
Density of only 1.8 g/cm³ (25% of steel) with tensile strength up to 300 MPa — comparable to high-grade steel. Drastically reduces transportation and installation costs.
Superior Corrosion Resistance
Resists acids, alkalis, salts, and a wide range of chemicals. Vinyl ester grating retained over 95% of strength after 1,000 hours in 5% sulfuric acid solution (ASTM D543).
Exceptional Slip Resistance
Gritted surface achieves 0.65 friction coefficient (DIN 51130 R13) — ensuring worker safety in wet, oily, or slippery conditions.
Radio Transparency
Ideal for airport applications. Radio signal interference rate less than 1%. Frangible design complies with ICAO safety standards for airfield fencing.
Low Maintenance Costs
No painting or protective coatings needed. Maintenance costs up to 70% lower than steel. Design life exceeding 20 years.
UV & Color Stability
UV inhibitors ensure no significant fading for over 10 years. Standard colors: Green, Grey, Yellow, Black. Custom RAL/Pantone colors available.
Production Technology
Molded & Pultruded Processes
Molded Grating
One-piece construction produced through a mold-compression process. Perfect for applications requiring uniform load distribution and bi-directional strength. Ideal for chemical plants, water treatment, and general industrial flooring.
Pultruded Grating
Continuous manufacturing process producing profiles with superior unidirectional strength. The choice for heavy-duty applications and long spans. Offers 50% increase in tensile strength compared to molded options. Perfect for bridge decks and heavy vehicular areas.
