Hengshui Ruibin New Materials LLC, a leading manufacturer established in 2019 with a 1,000-3,000 m² factory and ISO9001-certified production, proudly presents our Pultruded FRP Grating 25mm Depth 2440x3660mm with I-Beam Design — engineered for the most demanding heavy-duty environments. Our gratings combine the strength of pultruded fiberglass with an innovative I-beam profile, delivering exceptional load-bearing capacity while remaining lightweight and corrosion-resistant. Whether you need a robust flooring solution for chemical plants, offshore platforms, or industrial walkways, this grating offers a long-lasting, maintenance-free alternative to steel.
The 25mm depth and 2440x3660mm panel size are specifically designed to meet high-traffic, high-load requirements. Each panel features an I-beam cross-section that maximizes rigidity and distributes weight evenly, ensuring safety and stability even under heavy machinery or frequent foot traffic. With a 25-year lifespan in typical industrial settings, our grating reduces total cost of ownership significantly.
Below are the key technical specifications and dimensions for your reference:
| Property | Value |
| Profile Depth | 25 mm |
| Panel Width | 2440 mm |
| Panel Length | 3660 mm |
| I-Beam Pitch (Center-to-Center) | 30 mm (standard) |
| Load Bearing (Uniform Distributed Load) | Up to 500 kg/m² (depending on span) |
| Fire Resistance | Class A (self-extinguishing, optional) |
| Corrosion Resistance | Excellent (resistant to acids, alkalis, and solvents) |
| Weight per Panel | Approx. 45 kg (lightweight) |
Key Features & Benefits
- I-Beam Structural Design – The pultruded I-beam shape provides superior strength-to-weight ratio, allowing longer spans without sagging. This reduces the need for extra support structures, saving installation costs.
- Heavy Duty Load Capacity – Tested to withstand concentrated loads up to 1000 kg per bearing bar (depending on configuration). Ideal for forklift traffic, heavy equipment platforms, and crane runways.
- Corrosion & Chemical Resistance – Made from vinyl ester or polyester resin with continuous glass fibers, the grating resists rust, rot, and chemical attack. Suitable for harsh environments like wastewater treatment, mining, and marine applications.
- Anti-Slip Surface – Standard grit-top surface (silica sand or aluminum oxide) provides excellent traction even when wet or oily, meeting OSHA safety requirements.
- Low Maintenance & Long Service Life – No painting, coating, or galvanizing needed. Expected lifespan exceeds 20 years in most industrial settings, significantly reducing lifecycle costs.
- Lightweight & Easy Installation – At only 45 kg per panel, handling and cutting on-site are straightforward. Modular design allows quick assembly with clips or fasteners.
- Customizable Dimensions & Colors – Panels can be cut to size, and resin color can be selected (yellow, gray, green, etc.) to match safety codes or branding.
- Fire Retardant Options Available – Upon request, we can add fire-retardant additives to achieve Class A or Class B ratings per ASTM E84.
Typical Applications
- Chemical plant flooring, platforms, and trench covers
- Oil & gas offshore platforms and walkways
- Water and wastewater treatment plant catwalks
- Food processing facility floors (non-slip, easy to clean)
- Marine docks, piers, and ship decking
- Power generation plant gratings (cooling towers, turbine areas)
- Mining and heavy industrial access ways
- Commercial mezzanines and storage areas
Our manufacturing process follows strict ISO9001 quality control standards, ensuring consistent dimensions, mechanical properties, and surface finish. Every panel is inspected before shipment. We also offer additional services such as panel cutting, notching, and custom resin formulations to meet specific load or chemical resistance requirements.

Frequently Asked Questions
-
Q: What is the difference between pultruded FRP grating and molded FRP grating?
A: Pultruded gratings, like our I-beam design, are made by pulling continuous fibers through a resin bath and a heated die, resulting in a high-strength, unidirectional profile. Molded gratings are made by pouring resin and chopped fibers into a mold. Pultruded gratings offer higher load capacity in one direction and are ideal for heavy-duty applications, while molded gratings are often more economical for lighter loads. -
Q: Can this grating be used in food processing areas?
A: Yes, it is suitable for food processing. The non-porous, corrosion-resistant surface is easy to clean and does not harbor bacteria. We can also supply a smooth top surface if required, though the anti-slip version is recommended for wet areas. -
Q: What is the maximum span for this 25mm depth grating?
A: The maximum safe span depends on the load and support conditions. For a uniform load of 500 kg/m², the recommended span is up to 600 mm. For concentrated loads, spans can be up to 400 mm. Please consult our technical team for a detailed load table based on your specific configuration. -
Q: Are cutting or custom sizes available?
A: Yes, we can cut panels to your exact dimensions, including custom lengths, widths, and cutouts for pipes or columns. There may be a minimum order quantity for custom sizes. Contact us for a quotation. -
Q: How do I install the grating?
A: Installation is simple using standard grating clips, hold-down fasteners, or counter-sunk screws. The panels can be easily cut on-site with a diamond blade or abrasive saw. We provide installation guidelines and accessories upon request. -
Q: Is the grating UV resistant?
A: Standard UV resistance is achieved by adding UV stabilizers to the resin. For outdoor applications with prolonged sun exposure, we recommend a UV-resistant coating or a special resin formulation. This option is available upon request. -
Q: What colors are available?
A: Our standard colors are yellow, gray, and green. Custom colors can be matched to your requirements (e.g., safety orange, blue). Color is integrated into the resin during pultrusion, so it will not chip or peel. -
Q: What is the typical lead time for a standard order?
A: For standard panels (25mm depth, 2440x3660mm), the lead time is typically 15–20 working days after order confirmation, depending on volume. Custom orders may require additional time. Express shipping options are available for urgent projects.
