Fiberglass Grating for Corrosive & Heavy-Duty Environments
FRP (Fiber Reinforced Plastic) grating is a structural flooring material manufactured from continuous E-glass fiber reinforcement and thermosetting resin. Molded grating is produced by laying glass fibers in a mold in both directions and saturating them with resin, creating a one-piece panel with exceptional bi-directional strength. Pultruded grating is manufactured by pulling continuous glass fibers through a resin bath and heated die, resulting in higher stiffness and load capacity.
Our FRP grating products are available in standard square mesh (38×38 mm, 40×40 mm, 50×50 mm), mini mesh (19×19/38×38 mm, 20×20/40×40 mm), micro mesh and rectangular mesh configurations. Standard panel sizes include 1220×3660 mm, 1220×2440 mm, 1000×2000 mm, 915×3050 mm and other dimensions. Available resin systems include orthophthalic polyester, isophthalic polyester and vinyl ester for different chemical exposure levels.

Material Advantages
Why Choose FRP Grating?
FRP grating combines corrosion resistance, lightweight construction, high strength and slip safety, making it superior to traditional materials in many demanding industrial environments.
01
Superior Corrosion Resistance
FRP grating does not rust and resists acids, alkalis, salt water and most industrial chemicals. The resin system can be matched to the specific chemical exposure for optimal performance.
02
Lightweight & High Strength
With a density approximately 1/4 that of steel, FRP grating is easy to handle and install while providing excellent load-bearing performance. Pultruded grating weighs only 25% of steel and 70% of aluminum on an equal volume basis.
03
Slip Resistant Surfaces
Gritted anti-slip surfaces maintain high performance even after one million footfalls. Concave (meniscus) surfaces provide superior slip resistance in most environments.
04
Non-Conductive
FRP grating is non-conductive and non-magnetic, making it suitable for electrical infrastructure, switchgear and other sensitive applications.
05
Free Engineering Support
We provide free CAD design drawings, engineering calculations and technical recommendations to ensure your grating specification is correct for the load, span and environment.
06
B2B Industrial Supply
Suitable for industrial distributors, construction companies, OEM customers and bulk purchasing programs.

Material Comparison
FRP Grating vs. Steel, Aluminum & Timber
The following table provides a general comparison of typical properties for FRP grating versus traditional grating materials. Values are representative and may vary depending on specific grades and formulations.
| Property | FRP Grating | Steel Grating | Aluminum Grating | Timber |
|---|---|---|---|---|
| Specific Gravity | ~1.9 g/cm³ | 7.85 g/cm³ | 2.70 g/cm³ | 0.6–0.8 g/cm³ |
| Weight (Equivalent Volume) | ~25% of steel; ~70% of aluminum | Heavy | Light | Medium |
| Corrosion Resistance | Excellent; resin system matched to environment | Requires coating or galvanizing | Good in many environments | Poor; requires protection |
| Slip Resistance | Excellent (gritted/concave surfaces) | Depends on surface pattern | Depends on surface profile | Can become slippery when wet |
| Electrical Conductivity | Non-conductive | Conductive | Conductive | Variable with moisture |
| Maintenance Requirement | Low; no painting required | High (coating inspection) | Low | High (sealing, treatment) |
| Typical Service Life | Long in matched environment | Tied to corrosion protection | Good in suitable environments | Dependent on moisture |
| Fire Performance | Fire-retardant grades available | Non-combustible | Non-combustible | Combustible |
* Values are typical reference values for common grades and may vary depending on specific products and formulations. FRP grating offers the best combination of corrosion resistance, lightweight construction and low maintenance. Steel provides maximum stiffness and load capacity. Aluminum is a lightweight metallic alternative. Timber is economical but requires more maintenance. Always confirm with our technical team for your application.

Selection Guide
How to Choose FRP Grating
The correct grating type, mesh size, thickness and resin system should be selected based on span, load, chemical exposure and environmental conditions.
01
Grating Type
Choose molded grating for bi-directional strength and impact resistance; choose pultruded grating for higher stiffness, longer spans and heavier concentrated loads.
02
Mesh & Thickness
Select mesh size based on required open area, drainage and ball-fall safety requirements. Thickness determines load capacity and deflection.

Surface & Compliance
Specify gritted surface for slip safety, concave for general use, or covered for odor containment. Confirm fire rating, ASTM F3059 or other compliance requirements.
Manufacturing
Controlled Production for Consistent Quality
Precision fiber placement, resin impregnation and curing are critical for reliable FRP grating performance.
PROCESS / 01
Fiber Preparation
Continuous E-glass fibers are arranged in both directions for molded grating, or in the load direction for pultruded grating.
PROCESS / 02
Molding / Pultrusion
Fibers are saturated with resin and shaped in a heated mold (molded) or pulled through a heated die (pultruded) to form the grating structure.
PROCESS / 03
Inspection & Testing
Panels are inspected for dimensional accuracy, mesh uniformity, surface quality and load performance.
PROCESS / 04

FAQ
Frequently Asked Questions About FRP Grating
What is FRP grating?
FRP (Fiber Reinforced Plastic) grating is a structural
flooring material made from glass fiber reinforcement
and thermosetting resin. It is used for industrial
platforms, walkways, trench covers and stair treads
as a corrosion-resistant alternative to steel and
aluminum grating.
What is the difference between molded and pultruded FRP grating?
Molded grating has a square mesh pattern and offers
excellent bi-directional strength and impact
resistance. Pultruded grating has a rectangular mesh
pattern and offers higher stiffness and load capacity
for longer spans and heavier concentrated loads.
Do you provide free design drawings?
Yes. We provide free CAD design drawings and panel
layouts. Simply send us your span, load requirements,
chemical exposure and dimensions, and our engineering
team will deliver the drawings typically within 24–48
hours.
What is the maximum span for FRP grating?
Maximum span depends on grating type, thickness, load
and allowable deflection. Molded grating typically
spans up to 1200 mm for moderate loads; pultruded
grating can span up to 1500 mm or more for heavier
loads. Contact us for free load and deflection
calculations.
What resin systems are available?
Orthophthalic polyester for general industrial use;
isophthalic polyester for enhanced corrosion
resistance; vinyl ester for maximum chemical
resistance in aggressive environments.
What is the temperature range of FRP grating?
FRP grating typically operates from -80°C to +140°C
depending on the resin system. Confirm the specific
temperature limits for your selected resin.
Can FRP grating be cut on site?
Yes. FRP grating can be cut on site using standard
tools (angle grinder, skill saw) with appropriate
dust control. Edge sealing may be required depending
on the specification.
Is FRP grating slip resistant?
Yes. Gritted anti-slip surfaces maintain high
performance even after one million footfalls.
Concave (meniscus) surfaces provide superior slip
resistance in most environments.
Is FRP grating RoHS compliant?
RoHS compliance can be provided for applicable resin
systems and documentation requirements. Please
confirm when requesting a quotation.
What information do you need for a quotation?
Please provide the grating type (molded or pultruded),
mesh size, thickness, panel dimensions, quantity,
span, load requirements, chemical exposure and any
special requirements such as fire rating or slip
resistance.
