As a leading manufacturer based in Hengshui, Hebei, China, Hengshui Ruibin New Materials LLC specializes in high-performance FRP products. Our FRP Pultruded Grating with a thickness of 1.5 inches and a 2 x 2 inch mesh is specifically engineered for demanding environments like wastewater treatment plants. Combining exceptional corrosion resistance with lightweight construction, this grating offers a durable, low-maintenance alternative to traditional steel or aluminum gratings, ensuring long service life in harsh chemical and moisture-laden conditions.
Manufactured through advanced pultrusion technology, each panel is uniform in strength and free from defects. The 1.5-inch thickness provides substantial load-bearing capacity while maintaining a low weight that simplifies handling and installation. The 2 x 2 inch open mesh design allows for efficient drainage and ventilation, preventing slip hazards and reducing the buildup of debris. Whether used for walkways, platforms, trench covers, or safety barriers, this grating delivers reliable performance year after year.
Our product is backed by ISO9001 certification, reflecting our commitment to quality control and consistent production standards. With a factory area of 1,000–3,000 square meters and a skilled team of 101–200 employees, we ensure timely delivery and rigorous quality checks at every stage. Below, we detail the key specifications and benefits that make this grating an ideal choice for wastewater treatment applications.
Key Features & Technical Specifications
- Material: High-quality fiberglass reinforced polyester resin, offering excellent resistance to corrosion, UV, and chemicals.
- Thickness: 1.5 inch (38 mm) – provides high stiffness and load capacity while remaining lightweight.
- Mesh Size: 2 inch x 2 inch (50 mm x 50 mm) – allows debris and water to pass through easily, reducing slip risk.
- Surface Finish: Grit-top (anti-slip) surface standard; smooth surface available on request.
- Weight: Approximately 8–10 kg/m² depending on resin content – significantly lighter than steel grating, reducing installation costs.
- Load Capacity: Engineered to withstand concentrated loads up to 500 PSF (pounds per square foot) – suitable for heavy foot traffic and light industrial vehicles.
- Color Options: Yellow, green, grey, or custom colors – easy to identify safety zones.
- Customization: Panel sizes, cutouts, and resin types (e.g., vinyl ester for higher chemical resistance) are available upon request.
- Non-Conductive: Safe for electrical environments – does not conduct electricity like metal gratings.
- Low Maintenance: No need for painting, coating, or galvanizing – resists rust and rot.

Benefits for Wastewater Treatment Applications
- Corrosion Resistance: FRP does not rust or corrode when exposed to chemicals, chlorine, hydrogen sulfide, or moisture – ideal for aeration basins, clarifiers, and chemical feed areas.
- Lightweight & Easy Installation: At one-third the weight of steel, workers can carry and install panels without heavy lifting equipment, reducing labor costs and project time.
- Slip Resistance: The grit-top surface provides excellent traction even when wet, minimizing accidents in high-traffic walkways.
- Low Lifecycle Cost: No need for painting, galvanizing, or frequent replacement – saves money on maintenance over the long term.
- Non-Conductive & Non-Magnetic: Safe for use near electrical equipment and sensitive instrumentation.
- UV Stability: Resistant to degradation from sunlight, suitable for outdoor installations.
- Customizable: Available in various panel sizes, shapes, and resin formulations to meet specific project requirements.

Frequently Asked Questions
-
What is the load capacity of this grating?
Standard panels support up to 500 PSF concentrated load. For higher loads, we can customize the thickness or resin content – please consult our technical team. -
Can this grating be used in contact with strong acids?
Yes, the standard polyester resin resists many acids. For stronger chemicals, we recommend vinyl ester resin – available upon request. -
What panel sizes are available?
Standard panels are 4 ft x 8 ft (1220 mm x 2440 mm). Custom sizes can be cut to order with minimal waste. -
How do I install the grating?
Installation is simple with clips, screws, or embedding. We provide installation guides and accessories upon request. -
Is the grating fire-resistant?
Standard FRP has a self-extinguishing property (ASTM E84 Class I or II). For stricter fire ratings, we offer halogen-free resin options. -
What is the typical lead time for an order?
For standard quantities, 15–25 working days after deposit. Custom orders may require additional time. -
Do you provide samples?
Yes, we provide free small samples (shipping costs apply). Contact us for details. -
