Molded FRP Grating

– Durable Fiberglass Grating for Corrosive Environments

Molded FRP grating from Preet is engineered for performance in the harshest industrial and commercial environments. Whether used in chemical plants, offshore platforms, or municipal walkways, our fiberglass floor grating provides exceptional corrosion resistance, strength, and safety with minimal maintenance.

Why Choose Molded Fiberglass Grating?

Unlike traditional metal grating, molded FRP grating is formed as a one-piece composite, ensuring bidirectional strength and chemical resistance. The grating is manufactured using a thermoset resin matrix (ISO, Orthophthalic, or Vinylester), reinforced with continuous fiberglass strands, making it ideal for highly corrosive or wet environments.

Molded vs. Pultruded FRP Grating – What's the Difference?

Molded grating is manufactured by combining resin and glass in a mold and curing it into a solid panel. Pultruded grating, on the other hand, is made by pulling fiberglass rovings through resin and forming them into load bars. Each has its unique advantages:

Property	Molded FRP Grating	Pultruded FRP Grating
Strength Direction	Bidirectional	Unidirectional
Corrosion Resistance	Excellent	Very Good
Open Area	Up to 70%	More limited
Weight	Light	Lighter
Cost	More economical	Slightly higher
