Detailed Product Description
Our heavy-duty fiberglass grating is manufactured using a continuous glass fiber reinforcement and a thermosetting resin matrix through the pultrusion process, ensuring consistent quality and high strength-to-weight ratio. The 2.5-inch thickness provides a robust cross-section capable of supporting heavy forklift traffic and concentrated loads, while the 1.5-inch center-to-center spacing between bearing bars offers a balance between strength and open area. The 60% open area not only facilitates rapid drainage but also allows light and air to pass through, reducing moisture buildup in enclosed areas.
The grating features a concave-convex surface profile that enhances slip resistance, exceeding OSHA safety standards. It is available with a grit-top surface for additional traction in extreme conditions. Each panel is manufactured with a UV inhibitor to prevent yellowing and degradation from sunlight exposure. Additionally, we offer optional fire-retardant resin formulations that meet ASTM E-84 Class I or Class II flame spread ratings.
Compared to traditional steel grating, our fiberglass grating is 70% lighter, making it easier to handle and install without heavy lifting equipment. It is also immune to electrochemical corrosion, eliminating the need for painting or galvanizing. This translates to lower lifecycle costs and reduced downtime for maintenance. The material is non-conductive and non-magnetic, making it safe for use in electrical substations, MRI rooms, and other sensitive areas.

Frequently Asked Questions (FAQ)
1. What is the maximum span for this grating?
The maximum safe span depends on the load and resin type. For a uniform load of 300 psf, a typical span of 24 inches is recommended. For heavier loads, shorter spans or additional support may be required. Please consult our engineering team for specific span calculations.
2. Can this grating be used in corrosive environments?
Yes, it is highly resistant to a wide range of chemicals, acids, and alkalis. For extreme chemical exposure, we recommend the vinyl ester resin option. Our standard isophthalic polyester resin is suitable for most industrial environments.
3. Is this grating UV resistant?
Yes, we add UV inhibitors to the resin to prevent degradation and color fading from prolonged sunlight exposure. For outdoor applications, this ensures long-term durability.
4. What colors are available?
Standard colors include yellow, gray, green, and blue. Custom colors can be matched to your requirements with a minimum order quantity. Please inquire for details.
5. Do you offer custom sizes?
Yes, we can cut panels to your exact dimensions, including holes, cutouts, and notches. Custom panel sizes are available upon request with a short lead time.
6. How do I install this grating?
Installation is straightforward using clips, screws, or channel frames. We provide installation guidelines and recommend using stainless steel or fiberglass fasteners to maintain corrosion resistance. No welding is required.
7. What is the typical lifespan of this grating?
With proper installation and minimal maintenance, our fiberglass grating can last 20–30 years or more, even in harsh environments. Its resistance to rot, corrosion, and UV ensures a long service life.
8. Can you provide samples before bulk order?
Absolutely. We offer free samples (size 4x4 inches) for testing. You only need to cover the shipping cost. Contact our sales team to request samples.
