A Complete Guide to Selecting the Best Composite Grating Solution

Choosing the right FRP grating is essential for ensuring safety, durability and long-term performance in industrial and offshore environments.

With different manufacturing processes, resin systems, load ratings and surface options available, selecting the correct FRP grating requires a clear understanding of your application requirements.

At Endura, we help customers select customized FRP grating solutions designed for offshore wind, marine, industrial and energy applications.

1. Understand Your Application Environment

The operating environment is the first factor to consider when selecting FRP grating.

Different industries require different performance characteristics.

Offshore & Marine Applications

For offshore wind platforms, oil & gas facilities and marine structures, FRP grating must withstand:

• Saltwater exposure
• High humidity
• UV radiation
• Strong winds
• Continuous corrosion risks

Recommended options:

✔ Vinyl ester resin FRP grating

✔ Phenolic FRP grating for fire-sensitive areas

2. Choose Between Molded and Pultruded FRP Grating

FRP grating is mainly manufactured through two processes.

Molded FRP Grating

Molded grating is manufactured by placing fiberglass reinforcement layers into a mold and combining them with resin.

Advantages:

• Excellent corrosion resistance
• Bi-directional strength
• Good impact resistance
• Flexible customization

Typical applications:

• Walkways
• Platforms
• Chemical facilities
• Water treatment plants

3. Select the Right Resin System

The resin system determines the chemical resistance, fire performance and service life of FRP grating.

Polyester Resin

Suitable for:

• General industrial applications
• Indoor environments
• Cost-effective solutions

4. Choose the Right Surface Type

The surface finish directly affects safety.

Common options include:

Concave Surface

• Natural slip resistance
• Suitable for general industrial applications

Grit Surface

• Maximum slip resistance
• Recommended for offshore and wet environments

Covered Surface

• Provides a closed walking surface
• Prevents small objects from falling
