FRP Grating Aisle Shipment Completed for Industrial Walkway Applications
Recently, PRS completed the packing and shipment of a batch of FRP grating aisles, which were securely loaded and dispatched to the project site. These grating panels will be used as industrial walkways and access aisles in corrosive operating environments, where long-term safety, durability, and low maintenance are critical.
This shipment reflects PRS's experience in supplying reliable FRP grating solutions for industrial plants, especially in electrochemical, chemical, and hydrometallurgical applications.
What Is FRP Grating?
FRP grating, also known as fiberglass reinforced plastic grating, is a composite material made from glass fiber as reinforcement and unsaturated polyester resin as the matrix.
It is formed into a multi-cell, grid-like panel structure designed to provide both mechanical strength and corrosion resistance.
Compared with traditional metal grating, FRP grating features:
- Low material density (≤ 2 kg/dm³)
- High strength exceeding aluminum and ordinary carbon steel
- Excellent resistance to acid, alkali, and chemical corrosion
- Electrical insulation and flame-retardant properties
These characteristics make FRP grating an ideal choice for FRP aisle systems in harsh industrial environments.
Manufacturing Methods: Molded and Pultruded FRP Grating
The FRP grating supplied by PRS can be produced using two main manufacturing processes:
Molded FRP Grating
Molded grating is manufactured by interweaving glass fibers in multiple directions and impregnating them with resin, followed by integral molding under controlled conditions.
This process creates a regular rectangular mesh structure with isotropic mechanical properties, meaning strength is distributed evenly in both directions.
Pultruded FRP Grating
Pultruded grating is produced by pulling continuous glass fibers through a resin bath and heated die, forming high-strength load-bearing profiles that are then assembled into grating panels.
This type is suitable for applications requiring higher directional load capacity.
Mechanical Performance and Service Life
FRP grating exhibits bi-directional isotropic mechanical behavior, with compressive strength reaching up to 1 ton, depending on panel thickness and grid size.
Thanks to its corrosion-resistant resin system and fiberglass reinforcement, the expected service life exceeds 50 years under normal industrial operating conditions.
Unlike steel grating, FRP grating does not rust, does not require regular repainting, and maintains stable performance even in highly corrosive environments.
Applications of FRP Grating Aisles
FRP grating aisles are widely used in industries where corrosion resistance and safety are essential, including:
- Electrolytic tankhouses and electrowinning workshops
- Chemical plants and petrochemical facilities
- Wastewater treatment plants
- Marine and offshore platforms
- Industrial walkways, trench covers, and access platforms
In electrowinning and chemical environments, FRP grating provides reliable anti-slip performance, even under wet, acidic, or chemically aggressive conditions.
Installation and Customization Advantages
FRP grating panels can be easily cut and adjusted on site without heavy equipment.
Common panel sizes such as 1220 × 3660 mm are available, with thickness options ranging from 25 mm to 50 mm, allowing flexible adaptation to different load and walkway requirements.
Color options-including yellow, gray, green, red, and blue-can be customized to meet safety identification or plant design standards.
