Fiberglass Steel Grating

Fiberglass Grating offers more corrosion resistance than other forms steel grating. The square placement of continuous glass strands offers stronger bi-directional loading capabilities than more common molded rectangular fiberglass grating.

Fiberglass grating has many advantages over steel grating, not only for performance but also cost competitiveness. The wide range of gratings available can satisfy general industrial needs or high load requirements like forklift traffic.

Fiberglass steel grating features and benefits

  • Corrosion Resistance- based on the use of premium grade, is ophthalmic polyester or vinyl ester resin systems and a synthetic surfacing veil.
  • Lightweight Yet Durable - less than one-half the weight of steel grating allowing easy removal for access below floor level and installation with no heavy equipment and less manpower required.
  • Added Safety- durable grit surface, permanently bonded and baked to the grating surface, for a safe, slip-resistant walkway.
  • Fire Retardant- flame spread rating of 25 or less, according to ASTM E-84; meets the self-extinguishing requirements of ASTM D-635.
  • Maintenance Free- corrosion resist- ant and requires no scraping, sandblasting or painting; install it and forget it.
  • UV Protection - UV inhibitors included in the resin formulation, along with a surfacing veil and grit top surface for optimum protection from the effects of weathering.
  • Easily Fabricated - no need for lifting equipment or expensive tools; can be easily carried by two workers and cut using standard circular or saber saws fitted with carbide blades.
  • Electrically And Thermally Non-Conductive- providing additional worker safety.
  • Electronically Transparent- does not affect electromagnetic or radio wave frequencies.
