Custom FRP Grating for Industrial Walkways, Platforms and Corrosive Environments
Hebei Leihong FRP Technology Co., Ltd. manufactures moulded and pultruded fiberglass grating for wastewater treatment, chemical plants, marine facilities, mining projects, industrial platforms, trench covers and access systems.
FRP Grating for Platforms, Walkways and Trench Covers
Lightweight and Corrosion-Resistant Grating for Industrial Projects
FRP grating is widely used where steel grating is affected by corrosion, electrical conductivity, high maintenance or difficult installation conditions.
Fiberglass grating combines glass-fiber reinforcement with resin to provide strength, corrosion resistance, non-conductive properties and long-term service performance.
We manufacture moulded and pultruded grating in different thicknesses, mesh sizes, panel dimensions, resin systems, colors and surface types.
Grating Structures for Different Load and Application Requirements
Grating type should be selected according to load direction, support spacing, traffic conditions, corrosion environment and required surface performance.
Moulded FRP Grating
Bidirectional load-bearing structure with square or rectangular mesh for industrial access areas.
- Bidirectional strength
- Easy field cutting
- Good corrosion resistance
Pultruded FRP Grating
Unidirectional load-bearing bars for applications requiring longer spans and higher directional strength.
- Higher directional stiffness
- Suitable for longer spans
- Custom bearing-bar spacing
Covered FRP Grating
Grating combined with a solid FRP plate for closed surfaces and improved containment.
- Closed walking surface
- Improved spill control
- Optional anti-slip top
Micro-Mesh FRP Grating
Smaller mesh openings for improved walking comfort and reduced object drop-through.
- Smaller openings
- Improved pedestrian comfort
- Suitable for public-access areas
Heavy-Duty FRP Grating
Reinforced grating for higher loads, industrial traffic and demanding access platforms.
- Increased thickness
- Higher load capacity
- Project-specific support spacing
Custom-Cut FRP Grating
Panels cut according to drawings, openings, pipe locations and site dimensions.
- Drawing-based cutting
- Custom openings and shapes
- Edge sealing available

Resin Systems for Different Corrosion and Fire Requirements
Resin selection affects chemical resistance, weather performance, fire properties and service life.
Orthophthalic Polyester
General-purpose industrial applications with moderate exposure.
Isophthalic Polyester
Improved corrosion resistance for wastewater and industrial use.
Vinyl Ester
Higher chemical resistance for aggressive corrosive environments.
Flame-Retardant Resin
For projects requiring improved flame-spread performance.
UV-Resistant System
For outdoor grating exposed to sunlight and weather.
Application-Specific Resin
Selected according to chemical, temperature and service conditions.
Grating Selection Should Match Load, Span and Support Conditions
Important Factors Before Selecting FRP Grating
Thickness alone does not determine performance. Grating type, clear span, bearing direction, load type and allowable deflection should be reviewed together.
Clips and Fabrication Support for Grating Installation
M-Clips
Common clips for securing moulded grating panels to supports.
L-Clips
Used for edge fixing and selected installation conditions.
C-Clips
Connect adjacent grating panels and reduce movement.
Hold-Down Clips
Secure grating to structural supports and frames.
Custom Cutting
Panels cut according to drawings and site dimensions.
Edge Sealing
Cut edges can be resin sealed when required.
From Specification Review to Finished FRP Grating
Application Review
Confirm environment, access type, load and project quantity.
Specification Selection
Confirm type, thickness, mesh, panel size and resin.
Load and Span Review
Evaluate support spacing and design requirements.
Production
Complete moulding or pultrusion according to specification.
Custom Fabrication
Cut panels, openings and project-specific shapes.
Surface Finishing
Complete grit, covered surface or edge sealing as required.
Inspection
Check size, thickness, mesh, surface and appearance.
Packing and Delivery
Prepare labelled panels and export packaging.
Inspection Focused on Dimensions, Structure and Surface Quality
FRP grating inspection should confirm that panel dimensions, thickness, mesh, surface, resin and fabrication details match the purchase specification.
Load data, tolerance requirements and inspection checklists can be confirmed before production.
Typical FRP Grating Projects

Common Questions About FRP Grating
Contact us if your project requires load review, chemical-resistant resin, custom cutting or accessories.
Moulded grating provides bidirectional load distribution and easy field cutting. Pultruded grating provides higher directional strength and is often selected for longer spans.
Thickness should be selected together with clear span, load type, allowable deflection and support conditions.
Isophthalic polyester and vinyl ester are common choices. Final selection depends on chemicals, concentration, temperature and expected service life.
Yes. Panels can be cut to size with custom openings, curved edges, pipe cut-outs and project labels.
Yes. M-clips, L-clips, C-clips, hold-down clips and other accessories can be supplied.
