Fiberglass Grating | In-Stock Molded & Pultruded Products

Invest in a corrosion-resistant, fire-retardant flooring solution to create the safest possible workspace: fiberglass grating. Ideal for industrial, commercial, and architectural applications, FRP grating remains the gold standard for heavy-duty catwalks, gangways, work platforms, and more. Shop for our latest, in-stock molded and pultruded gratings.

Molded Gratings

At 4TAS-Supply, our molded gratings deliver considerable bi-directional strength due to their one-piece construction. During manufacturing, continuous fiberglass rovings (35%) are covered in a thermosetting resin (65%).  The benefits of molded fiberglass grating panels include:


  • Extended lifespan
  • Fire resistance
  • High strength-to-weight ratio
  • Corrosion resistance
  • Bi-directional strength
  • Impact resistance
  • Lightweight
  • Slip resistance
  • Low maintenance
  • Electrically and thermally non-conductive (custom option available with a conductive/dissipative surface for electrostatic discharge if required)

FGI-AM Resin System

Conductive Top Grating

FGI-AM Resin System

 Fibergrate has developed a unique resin system that has been successfully tested to inhibit the growth of bacteria on the surface of the composite product that, in some cases, can degrade or corrode the product. FGI-AM is an isophthalic polyester resin system with an ASTM E84 flame spread rating index of 25 or less, is USDA approvable, and offers superior slip and corrosion resistance.

Pultruded Gratings

Fibergrate pultruded gratings offer corrosion resistance, flame retardancy, and exceptional durability. Pultruded FRP grating is made by drawing fiberglass rovings (70%) through resin (30%) and the heated dies of a pultrusion machine. Pultruded fiberglass grating offers many of the same benefits as molded gratings, with increased stiffness at the cost of bi-directional strength.
