FRP Grating for Corrosive Industrial Environments
Explore molded and pultruded fiberglass grating for platforms, walkways, wastewater facilities and drainage areas. Share your span, loading and exposure requirements for a project specific recommendation.
Product range
Molded and Pultruded FRP Grating
The right construction depends on support direction, clear span, loading and the installation environment.
Molded FRP Grating
Integral molded construction with reinforcing fibers extending in two directions. A practical option for chemical plant floors, wastewater platforms and drainage covers.
- Multiple mesh, thickness and surface options
- Cut to project layout where suitable
- Resin selection based on service conditions
Pultruded FRP Grating
Parallel load bars with a defined primary span direction. Consider this construction when project loads or longer clear spans require a specific engineered configuration.
- Load bars oriented to the support layout
- Project specific span and deflection review
- Available with suitable surface treatments
Molded surface profile for pedestrian traction.
Additional traction where specified for the application.
Reduced openings where smaller dropped items are a concern.
Solid top options for applications requiring a more closed surface.
Material benefits
Designed Around Demanding Site Conditions
Performance depends on product construction, resin and installation details. Define the conditions first, then compare the proposed grating against the project requirements.
Corrosion resistant options
Select a suitable resin for the specific chemicals, concentration and temperature.
Lightweight construction
Fiberglass grating can simplify handling and installation compared with many metal alternatives.
Nonconductive material
Electrical and fire performance should be confirmed against the relevant project test requirements.
Surface traction options
Choose concave or grit surfaces based on pedestrian traffic, contaminants and cleaning needs.
Cut to layout
Plan panel sizes, support and cutouts before fabrication; seal cut edges when required by the specification.
Long term material planning
Assess installation, inspection and replacement costs for the actual operating environment.
Technical selection
FRP Grating Specifications and Selection Guide
The sizes below are common inquiry categories, not a stock or load rating. Confirm manufacturing availability, tolerances and performance for the selected construction.
| Nominal thickness | Mesh / opening to discuss | Typical selection questions |
|---|---|---|
| 25 mm | 38 × 38 mm or project specific | Pedestrian load, support spacing and deflection limit |
| 30 mm | 38 × 38 mm or project specific | Walkway layout, load direction and resin type |
| 38 mm | 38 × 38 mm or project specific | Platform loading, panel support and cutouts |
| 50 mm | Confirm construction and mesh | Heavy duty requirements need verified product load data |
| 65 mm | Confirm construction and mesh | Project specific engineering review required |
Other parameters to specify: panel dimensions, resin system, color, surface treatment, quantity, fixing method and delivery location. Panel sizes such as 1220 × 3660 mm and 1220 × 4000 mm should be confirmed for the selected tooling. Fasteners and grade must match the site environment.
Applications
FRP Grating Across Industrial and Public Sites
These are application examples. Project images and named case studies should be added only after verifying the installation details.

FRP Grating vs. Steel Grating
Use this table as a starting point for material selection. Structural performance, cost and maintenance should be compared using actual project specifications.
| Factor | FRP grating | Galvanized steel grating | Stainless steel grating |
|---|---|---|---|
| Chemical exposure | Dependent on resin and medium | Coating condition matters | Dependent on alloy and medium |
| Weight & handling | Typically lightweight | Generally heavier | Generally heavier |
| Electrical conductivity | Typically nonconductive* | Conductive | Conductive |
| Site cutting | Cutting and edge treatment per product guidance | Cut surfaces may need coating repair | Cutting and finishing per specification |
| Maintenance | Inspect fixings and surface condition | Inspect coating and corrosion | Inspect grade suitability and condition |
* Confirm tested electrical properties for the exact product. FRP is not automatically antistatic or approved for explosive atmospheres. No universal service life or cost saving can be inferred from material alone.

Review resin and reinforcement for the specified service environment.
Confirm mold, dimensions, surface and cutout details.
Agree dimensional and performance checks before production.
Confirm stacking, protection and transport requirements.
Technical FAQ
FRP Grating Selection Questions
How do I choose grating thickness for a given span and load?
Provide clear span, support direction, load type, load magnitude and acceptable deflection. Compare these requirements with load data for the exact mesh, thickness and construction. A universal span rule based on thickness alone is not reliable.
Which resin is suitable for my project?
Provide the chemical name, concentration, temperature and duration of exposure. Resin families can differ substantially; compatibility must be checked against the selected formulation and actual conditions.
Can FRP grating be cut and finished on site?
Many panels can be cut with suitable tools, dust controls and protective equipment. Follow the product instructions for cut edges and confirm support and fixing positions after cutting.
Can I request a custom color or panel size?
Share your color target, panel drawing, quantity and delivery date. We can confirm tooling, production feasibility and lead time in the quotation.
