Hengshui Ruibin New Materials LLC, a leading manufacturer established in 2019 with a 1,000–3,000 m² factory and a team of 101–200 experienced professionals, proudly presents our premium FRP Pultruded Grating featuring a 1" x 4" rectangular mesh, 1.5" depth, 40% open area, and self-extinguishing properties per UL 94. This product is engineered to deliver exceptional durability, corrosion resistance, and safety for demanding industrial environments. With an annual export value of US$2.5–5 million, we serve global markets including North America, Europe, and Southeast Asia, ensuring consistent quality and timely delivery.
Our FRP pultruded grating is manufactured using a continuous pultrusion process that combines high-strength fiberglass with premium resin systems, resulting in a lightweight yet robust structure. The 1" x 4" rectangular mesh design provides excellent load distribution, while the 1.5" depth offers sufficient stiffness for heavy-duty applications. The 40% open area ensures efficient drainage and ventilation, reducing slip hazards and accumulation of debris. The self-extinguishing characteristic (UL 94) makes it a safe choice for environments where fire safety is critical.
Key Features & Benefits
- Corrosion Resistance: Ideal for chemical plants, wastewater treatment, and marine environments where metal grating would rust.
- Lightweight & High Strength: Up to 75% lighter than steel, yet offers comparable strength, reducing installation costs and structural load.
- Fire Safety: Self-extinguishing per UL 94 – no flame spread, minimal smoke generation.
- Low Maintenance: Non-conductive, non-magnetic, and resistant to UV degradation (with optional coating).
- Customizable: Available in various colors, surface finishes (grit top for slip resistance), and panel sizes.

Frequently Asked Questions (FAQ)
- Q: What is the weight of this grating? A: Approximately 4.5–5.5 lb/ft² depending on resin type and panel size. Exact weight can be provided upon request.
- Q: Can this grating be used in outdoor environments? A: Yes, the standard resin offers UV resistance, and an optional UV coating is available for extended outdoor life.
- Q: Is the grating slip-resistant? A: The standard smooth surface provides moderate slip resistance. For enhanced safety, we recommend the grit-top surface option.
- Q: What is the maximum span for this grating? A: Maximum recommended span is typically 24–30 inches for pedestrian loads, but this depends on load requirements. Please consult our load table.
- Q: Do you provide custom sizes? A: Yes, we can cut panels to your exact dimensions. Custom shapes and cutouts are also available.
- Q: How is the grating shipped? A: Panels are bundled and packed on pallets, secured with straps. For small orders, we use cardboard protection.
- Q: What is the lead time? A: Standard sizes ship within 7–10 working days. Custom orders require 15–20 working days, depending on complexity.
- Q: Is the grating conductive? A: FRP is non-conductive, making it safe near electrical equipment. For antistatic requirements, a conductive grade can be engineered.
