Molded Fiberglass Grating

Product Overview

Molded fiberglass reinforced plastic (FRP) grating provides corrosion resistance in the most demanding environments. Manufactured by combining thermosetting resin with continuous fiberglass rovings in precision molds, each panel contains approximately 65% resin and 35% fiberglass rovings. This combination optimizes corrosion resistance, UV protection, and structural integrity.

Molded grating features:

Wide range of high-performance resins
Fire retardant, meeting ASTM E84 and ASTM D635
Electronically transparent and non-conductive
Easily fabricated and virtually maintenance free

Molded Fiberglass Grating

Molded Square Mesh

Our most popular FRP product, molded square mesh grating is available in 1”, 1-1/2”, and 2” depths. The 1” and 1-1/2” deep products are produced with a 1-1/2” square mesh while the 2” deep products are produced with a 2” square mesh. The square pattern of the panels provides bi-directional strength and facilitates easy layout and fabrication.

Popular resins include economical Corvex polyester, superior Vi-Corr vinyl ester, and other application specific resins. All products are available with the standard concave meniscus surface or optional grit surface (coarse or fine grit).

Molded Rectangular Mesh

Available in 1” deep, 1” x 4” pattern, rectangular mesh FRP gratings are commonly used for walkways and trench applications. When selecting rectangular mesh grating it is important to specify the span (rectangular opening) of the grating perpendicular to the supporting structure.

Like our square mesh products, popular resins include economical Corvex polyester, superior Vi-Corr vinyl ester, and other application specific resins. All products are available with the concave meniscus surface or the optional grit surface (coarse or fine grit).
