Fiberglass grating for industrial projects
Choose molded mesh or pultruded bearing-bar panels for walkways, platforms and access systems. Compare configurations, review the engineering inputs and send a panel schedule for quotation.

Two ways to build your walking surface
Fiberglass grating is also called fibreglass or GRP grating. The important choice is how the panel carries the load and fits the layout.

Molded vs pultruded grating
| Selection question | Molded grating | Pultruded grating |
|---|---|---|
| How is it made? | Glass reinforcement and resin form an integral grid in a mold. | Continuous pultruded bearing bars are joined with cross-rods. |
| Which direction spans? | Square-mesh panels can support two-direction layouts; check the selected panel's load data. | Bearing bars carry the main span. Cross-rods are not an equivalent load-bearing direction. |
| What geometry is specified? | Mesh, clear opening, panel depth, panel size and support around cutouts. | Bar shape, depth, spacing, cross-rod layout, panel size and bearing direction. |
| What controls the final choice? | Loads, supports, deflection, openings, resin and surface. | The same project checks, with the bearing bars aligned to the designed span. |

Match the resin to the environment
Identify chemical names, concentrations, exposure type and operating temperature. Discuss polyester or vinyl ester against that service; resin names alone do not establish compatibility.

For molded mesh, compare concave and gritted finishes. For pultruded bars, confirm the profile finish or bonded grit for the selected series. Match the surface to wet or dry use, footwear and cleaning, and specify the required slip-test method and acceptance criteria.
Check the full load case
State clear span, support width, uniform and concentrated loads, contact area and deflection limit. Cutouts, edge support and bearing-bar direction belong on the panel layout.
Request the applicable load dataMatch the documents to your panel
Download the current selection data and clip drawings. For a load/deflection table or test report, identify the panel and service conditions so the documents match the proposed supply.

For US, Canadian, Australian, New Zealand and UK enquiries, include the destination and required units. Panel specification, quantity, cutting, fixing kits, packing and freight determine the quoted scope.
Step 1
Quantity & samples
Send panel quantities or total area, your preferred configuration and sample needs. Minimum production quantity and sample arrangements are confirmed with the quotation.
Step 2
Whole panels or a cut plan
State the required finished sizes, openings, edge treatment, panel identification and fixing kits. We confirm the drawing and fabrication scope before order release.
Step 3
Packing & destination
Give the delivery country, port or postcode and site handling constraints. The quotation defines packing, freight scope and the agreed Incoterm.
Step 4
Production & transit
Share your required-on-site date. Production timing and transport time are confirmed separately after specification, quantity and destination review.
We will acknowledge your requirements within one business day and confirm the next step. A formal quotation follows specification and delivery review. Attach your layout to the enquiry, or describe the application and ask us to help shortlist a configuration.
Catalog dimensions identify standard section options, not live inventory. Confirm tooling, material, quantity and production timing in the quotation.

Fiberglass grating: selection & purchasing questions
Are fiberglass, fibreglass, FRP and GRP grating the same?
For the glass-reinforced panels in F1's range, these names describe the same material family. Fiberglass is the common US spelling; fibreglass and GRP are also used in the UK, Australia and New Zealand. Specify molded or pultruded construction, resin, geometry and project requirements rather than relying on the name alone.
How do I choose molded or pultruded grating?
Begin with the support layout and openings. Molded mesh suits many irregular cutouts and two-direction layouts; pultruded bearing bars provide a directional span. Compare the selected panel's load and deflection data before confirming thickness. Neither construction is automatically suitable for every load.
Which panel sizes and thicknesses are available?
The molded page lists mesh groups, depths, panel-size options, weights and open area. The pultruded page lists I-bar and T-bar series, depths and bar spacing. Download the current selection CSV or choose a row for quotation. Listed configurations are selection references, not a live-stock promise.
Can I request inch dimensions and US units?
Yes. State the required units and whether a dimension is nominal or exact. The page shows metric catalog values; inch equivalents are approximate conversions. A 25 mm panel is approximately 0.984 inches, not an exact one-inch stock specification.
What affects the price and minimum order?
Panel type, geometry, resin, surface, quantity, cutting, fixing kits, packing and destination affect the quotation. Send panel quantities or total area and the delivery port or postcode. Minimum quantity, sample arrangements, production timing and delivery scope are confirmed against that requirement.
Can I get load tables and a drawing review?
Send the series or mesh, clear span, support width, load type and footprint, deflection limit, resin and service conditions. Request the applicable grating load/deflection table and product documents. The CSV contains geometry and nominal weights; it is not an allowable-load table.
