1. Defining FRP Grating

FRP grating stands for Fiberglass Reinforced Plastic Grating. It is a composite material made of continuous glass fiber strands embedded in a polymer resin. The result is a strong, rigid panel structure with open mesh designed for walkways, trench covers, stairs, and platforms.

Unlike steel grating, FRP is non-metallic, corrosion-resistant, lightweight, and electrically non-conductive-making it ideal for hazardous or corrosive environments.

2. Types of FRP Grating

There are two main categories of FRP grating available from Preet:

• Molded FRP Grating – Produced by molding glass fibers in a heated mold with thermosetting resin. It offers equal strength in two directions and excellent chemical resistance.
• Pultruded FRP Grating – Manufactured via the pultrusion process, which aligns fiberglass strands in one direction, resulting in superior span and load-bearing performance.

Both types are available in various mesh sizes, thicknesses, and resin systems (such as vinyl ester for chemical industries).

3. Key Features of FRP Grating

• ✔ Corrosion-Resistant: Resists water, acids, alkalis, and salt.
• ✔ Slip-Resistant: Available with embedded quartz grit surface.
• ✔ Lightweight: Around one-third the weight of steel grating.
• ✔ Non-Conductive: Safe for use near electric equipment.
• ✔ Low Maintenance: No need for painting or galvanizing.

Preet also provides FRP grating clips for secure installation on frames, concrete, or metal structures.

4. Common Applications of FRP Grating

Thanks to its versatility, FRP grating is widely used in industries where durability and corrosion resistance are critical.

✓ Wastewater Treatment Facilities

Molded FRP grating is ideal for wet areas like clarifier walkways and aeration tanks due to its slip resistance and chemical tolerance.

✓ Offshore and Marine Platforms

FRP grating resists saltwater corrosion and UV exposure, making it ideal for ship decks, docks, and offshore oil rigs.

✓ Food & Beverage Processing

With non-conductive and hygienic properties, FRP grating is used in areas with regular washdowns and chemical exposure.

✓ Industrial Staircases and Platforms

FRP stair treads offer superior grip and safety in both indoor and outdoor applications.

✓ Drainage and Trench Covers

Our pultruded trench covers are a popular choice for roadways, chemical plants, and commercial facilities.

5. How FRP Grating Is Installed

FRP grating can be cut on-site using carbide or diamond blades and secured using clip fasteners. Preet offers guidance on layout planning, edge protection, and cut-to-size services.

For complete walkways or trench systems, we provide support for design and delivery of prefabricated sections.

6. Choosing the Right Grating for Your Project

The choice between molded or pultruded FRP grating depends on factors like load requirements, chemical exposure, panel span, and installation method.

• Use molded grating for high chemical resistance and bi-directional strength.
• Use pultruded grating for long spans, walkways, or structural loads.
