 FRP GRP Fiberglass Grating

Fiberglass molded grating, also known as FRP (Fiberglass Reinforced Plastic) molded grating, is a high-performance composite product widely used in industrial, commercial, and public infrastructure applications. It is manufactured by combining continuous fiberglass rovings with thermosetting resins, forming a one-piece, reinforced grid structure that offers outstanding strength, safety, and durability.

Compared to traditional materials such as steel, aluminum, or wood, fiberglass molded grating provides unique advantages-lightweight construction, corrosion resistance, electrical insulation, and anti-slip properties. These features make it an ideal choice for environments exposed to harsh chemicals, moisture, heavy loads, or extreme temperatures.

Key Features of Fiberglass Molded Grating
Fiberglass molded grating is engineered to provide a combination of mechanical strength, corrosion resistance, and safety features that outperform many traditional materials.

Corrosion Resistance: Resistant to acids, alkalis, seawater, and industrial chemicals.
High Strength-to-Weight Ratio: Strong enough to support heavy loads while being much lighter than steel.
Non-Conductive: Provides excellent electrical and thermal insulation, making it safer in electrical environments.
Anti-Slip Surface: Available with concave tops, sanded grit surfaces, or embedded quartz for slip resistance.
Fire Retardant: Meets ASTM E84 and other international fire safety standards when formulated with flame-retardant resins.
UV Resistant: Special UV inhibitors can be added to enhance outdoor durability.
Low Maintenance: Requires minimal upkeep compared to rust-prone steel gratings.
Design Flexibility: Produced in various colors, mesh sizes, thicknesses, and load ratings to suit diverse projects.
