38mm GRP Grating - Heavy-Duty Fiberglass Molded Grating

38mm GRP grating (also listed as 38mm FRP grating) is a molded fiberglass reinforced plastic panel engineered for industrial walkways and platforms where corrosion resistance, safety and long service life are required. This 38mm thickness offers an excellent balance between load capacity and light weight, making it a preferred option for chemical plants, wastewater facilities, marine platforms, bridges, and roof access walkways.

Key Features

 

Panel thickness: 38mm nominal depth for heavy-duty applications.

High strength-to-weight ratio: Supports pedestrian and light vehicular loads while remaining much lighter than steel.

Exceptional corrosion resistance: Resistant to saltwater, acids, alkalis, and most industrial chemicals.

Anti-slip surface options: Grit top or molded serrated surfaces available to meet slip resistance requirements.

Non-conductive: Provides electrical insulation-suitable for substation platforms and electrical enclosures.

UV stable: Formulations available with UV inhibitors for long outdoor exposure.

Low maintenance: No painting or coatings required; minimal lifecycle maintenance.

Easy installation: Panels can be cut on site and fixed with corrosion-resistant clips or fasteners.

Typical Product Applications

 

Common uses for 38mm GRP grating include:

• Industrial platforms and access walkways
• Trench covers and drainage channels
• Dock and marine decks
• Chemical and petrochemical plants
• Wastewater treatment plants
• Cooling tower walkways and service platforms
• Roof access walkways and HVAC service platforms

Pultruded and molded gratings have different span/load behavior. For 38mm molded GRP grating typical safe spans for pedestrian traffic range from 1.0 m to 1.5 m depending on loading and mesh pattern. For specific project loading (uniform and concentrated), please request our load/span tables or provide your load cases so our engineers can recommend exact panel selection.

38mm grating panels are easy to install:

• Panels can be mechanically fixed to support beams using stainless steel or FRP clamps and clips.
• Cutting: Diamond-tipped tools or abrasive saws recommended for clean edges.
• Edge protection: FRP angle or aluminum capping recommended for high traffic edges.
• Spacing: Allow for thermal expansion in long runs; typical clip spacing 300–600 mm depending on load.

Our 38mm GRP gratings are manufactured to comply with international norms and can be supplied with test certificates on request, including:

• ISO 9001 quality management
• Material test certificates (EN 10204 Type 2.2 or similar on request)
• ASTM and EN standard compliance for mechanical and fire test data depending on resin system

Compared to galvanized steel and timber, 38mm GRP grating offers:

• Significantly better corrosion resistance - ideal for coastal and chemical environments
• Lower long-term maintenance costs - no painting or anti-rust treatments
• Lighter weight - reduces handling and installation costs and allows for simpler support structures
• Non-conductive - increases safety around electrical installations

Routine maintenance is minimal:

• Periodic pressure washing to remove debris and chemicals
• Inspect fixing points and replace corroded fasteners (use stainless steel)
• Re-apply grit or replace panels only if surface wear is excessive (rare under normal use)

We offer 38mm GRP grating with choices including:

• Resin systems: standard polyester, vinyl ester (for stronger chemical resistance), phenolic (for enhanced fire performance)
• Surface finishes: grit-coated, serrated, or smooth
• Panel sizes & pre-cut shapes (rectangles, triangles) to minimize on-site cutting
• Edge capping, stair treads, handrails and FRP support profiles for turnkey solutions
