At Hengshui Ruibin New Materials LLC, we specialize in the manufacture of high-performance composite products. Our Pultruded FRP Grating 1.5 Inch Depth, 2.5" Center-to-Center, Class 1 Fire Rating, 60% Open Area combines advanced pultrusion technology with rigorous quality control to deliver a grating solution that excels in demanding environments. Designed for maximum strength, corrosion resistance, and safety, this product is the ideal choice for industrial flooring, walkways, and platforms where both performance and compliance are critical. Backed by our ISO9001-certified production facility and years of export experience, you can trust in the consistency and reliability of every panel.
This FRP grating features a 1.5-inch depth and 2.5-inch center-to-center spacing, providing a robust structural profile that supports heavy loads while maintaining a lightweight design. The 60% open area ensures excellent drainage, light transmission, and airflow, reducing slip hazards and enhancing worker safety. The Class 1 fire rating (per ASTM E84) means it meets stringent fire safety standards, making it suitable for use in oil & gas, chemical plants, marine, and other high-risk industries. Corrosion-resistant and non-conductive, it outperforms steel grating in harsh environments, offering a long service life with minimal maintenance.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum load capacity of this grating?
A: The load capacity depends on the panel size, support span, and configuration. For a standard 2.5" center-to-center spacing with 1.5" depth, the grating can support up to 200-300 lbs per square foot (approx. 975-1465 kg/m²) depending on span. We provide detailed load tables upon request. -
Q: Can I get custom colors or sizes?
A: Yes, we offer customization. Standard color is yellow, but other colors (gray, green, blue) are available. Panel sizes can be cut to exact dimensions, and we can also produce custom cutouts for pipes or equipment. -
Q: Is this grating suitable for outdoor use?
A: Absolutely. Our FRP grating includes UV inhibitors in the resin system to prevent degradation from sunlight. The 60% open area also allows rain and snow to pass through, reducing ice buildup. -
Q: How does the Class 1 fire rating compare to other ratings?
A: Class 1 (ASTM E84) is the highest rating for flame spread in building materials, with a flame spread index of 25 or less. This grating is commonly used in applications requiring strict fire safety compliance, such as oil platforms and chemical plants. -
Q: What is the weight difference compared to steel grating?
A: This FRP grating weighs about 4.5 kg per sqm, while a comparable steel grating (1.5" depth, 2.5" spacing) would weigh approximately 20-25 kg per sqm. That's an 80% weight reduction, making handling and installation much easier. -
Q: Do you provide installation instructions?
A: Yes, we provide detailed installation guides and recommend using stainless steel clips or fiberglass fasteners to secure the grating. Our technical support team can also assist with design and layout. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 7-15 days. Custom orders with special resin or colors may require 15-25 days. We ship from Tianjin or Qingdao port, and express shipping is available for urgent orders. -
Q: How long does this grating last?
A: In typical industrial environments, FRP grating can last 20+ years with minimal maintenance. Its resistance to corrosion, chemicals, and UV ensures long-term performance without rust or rot.
