Hengchen FRP Grating: Your Integrated Industrial Solution

Hengchen's FRP grating meets strict industry requirements through a wide range of specifications and deep customization capabilities.

Dimensions and Mesh Design:

Standard Panel Sizes: 1.22m x 3.66m (4' x 12') and 1m x 4m.

Standard Thickness: 25mm (1"), 38mm (1.5"), 50mm (2").

Common Mesh Patterns: 38mm x 38mm (1.5" x 1.5"), 50mm x 50mm (2" x 2").

Customization: We produce non-standard panel sizes and mesh configurations with a dimensional tolerance of ±1mm to fit complex project layouts.

Data Point: Our 38mm thick molded grating with a 38mm x 38mm mesh pattern supports a uniform distributed load of up to 4.8 kN/m² (tested to ASTM D695).

Materials and Resin Systems:

Resin Options: Isophthalic Polyester (for general industrial environments), Vinyl Ester (for superior resistance to strong acids and alkalis), and Phenolic (for top-tier fire resistance, meeting ASTM E84 Class A with a flame spread index ≤25).

Fiberglass: We use E-glass for its excellent performance-to-cost ratio or C-glass for enhanced corrosion resistance. Glass fiber content is maintained between 30-40% for optimal strength.

Environmental Compliance: Our production utilizes low-VOC resins, minimizing environmental impact and adhering to EU environmental standards.

Load Capacity and Mechanical Performance:

Load Ratings: Light-duty (pedestrian traffic, 1.5 kN/m²), Medium-duty (industrial work platforms, 4.8 kN/m²), and Heavy-duty (light vehicular traffic, 7.2 kN/m²).

Performance Data: Our 38mm thick molded fiberglass reinforced plastic grating has a compressive strength of 120 MPa, while our pultruded profiles achieve a tensile strength of 300 MPa (per ASTM D638). Deflection is controlled within a L/200 ratio.

Advantage: Weighing only one-quarter of steel grating, our product increases installation efficiency by up to 30%.

Surface Treatment and Slip Resistance:

Surface Types: Gritted Top (providing R13 friction coefficient under EN 14122), Concave/Meniscus Top (for moderate slip resistance), and Smooth Top (for easy cleaning).

Application Data: In wet and oily conditions, our gritted surface improves the friction coefficient by 40%, significantly reducing the risk of slips and falls.

Color and Appearance:

Standard Colors: Green, Grey, Yellow, and Black. UV inhibitors are added to ensure no significant fading for over 10 years.

Customization: We can match any color from the RAL or Pantone color systems to meet specific architectural or branding needs.

Aesthetics: We provide 3D renderings to help clients visualize the final installation.

Fire and Electrical Performance:

Fire Resistance: Our phenolic gratings are certified to ASTM E84 Class A, making them suitable for airports, offshore facilities, and other high-risk environments.

Insulation Properties: The material is non-conductive with a resistivity greater than 109Ω·cm, ideal for electrical substations, cable trenches, and sensitive installations.

Hengchen's FRP grating stands out in the global market for these core characteristics:

Lightweight and High-Strength: With a density of only 1.8 g/cm³ (25% that of steel), it offers a tensile strength of up to 300 MPa, comparable to high-grade steel. This drastically reduces transportation and installation costs.

Superior Corrosion Resistance: Our gratings resist acids, alkalis, salts, and a wide range of chemicals. When tested according to ASTM D543, our vinyl ester grating retained over 95% of its strength after 1000 hours of immersion in a 5% sulfuric acid solution.

Exceptional Slip Resistance: The gritted surface achieves a friction coefficient of 0.65 (DIN 51130 R13), ensuring worker safety in wet, oily, or slippery conditions.

Radio Transparency and Frangibility: Ideal for airport applications, our grating has a radio signal interference rate of less than 1% and a frangible design that complies with ICAO safety standards for airfield fencing.

Low Maintenance Costs: No need for painting or protective coatings. Maintenance costs are up to 70% lower than steel, with a design life exceeding 20 years.

Molded and Pultruded Processes

Molded Grating: A one-piece construction perfect for applications requiring uniform load distribution and bi-directional strength.

Pultruded Grating: Offers superior unidirectional strength, making it the choice for heavy-duty applications and long spans, with a 50% increase in tensile strength.
