Heavy Duty FRP Grating

Heavy duty FRP grating has better load-bearing capacity than general thickness FRP grating. strength products are required.

he load-bearing capacity of the FRP grating is closely related to its thickness. The load-bearing capacity of the 50mm thickness grating is about 6 tons, and the load-bearing capacity of the 65mm thickness grating is about 9 tons. High load-bearing capacity heavy duty FRP grating is required by large-scale construction sites, offshore oil platforms, and vehicular traffic.
The heavy duty FRP molded grating we provide includes square mesh grating and rectangular mesh grating(SuperSpan). The square mesh heavy duty grating has bidirectional loading, which helps the installation of grating and the uniform stress of supporting structure, and the bearing capacity is also enhanced. The SuperSpan design maintains a high resin/glass ratio, but is approximately 90% harder than the ordinary rectangular mesh molded grating of the same thickness. It provides a solution that can extend the application range of molded gratings to applications that require or expect a larger span.
The heavy duty FRP pultruded grating is designed for applications requiring heavier loads on the basis of long spans. It is engineered for vehicular traffic(up to Standard Truck formerly H20) or high and very long spans. And it is especially used to replace steel gratings in large spans. In addition, the design of our heavy duty FRP grating also complies with ADA.

Q1: How do you ensure the quality of FRP products?

A: All products are manufactured in our own factory under strict ISO-based quality control. We perform raw material testing, process monitoring, and final inspection to ensure every panel meets strength, durability, and corrosion-resistance requirements.

Q2: Where can FRP products be used?

FRP products are ideal for chemical plants, wastewater facilities, offshore platforms, walkways, platforms, stairs, and other areas that require corrosion resistance, lightweight structure, and long service life.

Q3: Do you provide after-sales support?

Yes. We provide clear documentation, installation guidelines (if needed), and technical support. If any quality issue is confirmed after delivery, we offer replacement, rework, or other agreed solutions.

Q4: Can you help with project-specific requirements?

Absolutely. Our team can suggest the right resin system, grating type, and surface finish for your application, and provide drawings or design assistance to ensure project success.
