What is Molded FRP Grating?
Molded FRP grating is a composite grating product formed through a precision molding process. Fiberglass strands are saturated with resin and placed in a mold, then cured under heat and pressure. The result is a one-piece, integral mesh panel that combines strength, chemical resistance, and slip protection.
Unlike metal gratings, molded FRP grating does not rust, conduct electricity, or require repainting. Its uniform construction provides equal strength in both directions, making it reliable for long-term use in harsh working environments.
Key Features of Molded FRP Grating
Corrosion Resistance – Withstands acids, alkalis, and solvents better than steel or aluminum.
Slip Resistance – Standard grit surface ensures worker safety in wet or oily conditions.
Lightweight but Strong – Easy to handle, install, and cut without heavy equipment.
Non-Conductive & Fire-Retardant – Safer for use in electrical and flammable environments.
Maintenance-Free – Long service life without frequent painting or coating.

Frequently Asked Questions (FAQ)
Q1: What is the difference between molded FRP grating and pultruded FRP grating?
A1: Molded grating is produced in a mold, giving it uniform strength in both directions, while pultruded grating has higher glass content and greater load-bearing strength in one direction. Molded grating is more suitable for corrosive and pedestrian-heavy environments.
Q2: Can molded FRP grating be customized in size and color?
A2: Yes, we provide custom cutting services and a wide range of RAL colors to meet project-specific requirements.
Q3: Is molded FRP grating fire-resistant?
A3: Yes, depending on resin selection, molded grating can meet ASTM E-84 and other fire-retardant standards.
Q4: How does molded FRP grating compare in cost to steel grating?
A4: The upfront cost may be slightly higher, but the long-term savings from reduced maintenance, corrosion resistance, and lightweight handling make it more economical.
Q5: Where is molded FRP grating most commonly used?
A5: It is widely used in chemical processing plants, offshore oil rigs, shipyards, wastewater treatment facilities, and infrastructure projects requiring durable, anti-slip flooring.
