FRP Gratings

FRP Gratings:

Ferrotech is one of the leading manufacturers of FRP Molded Gratings and is known in the industry for giving corrosion resistance, durable and high strength FRP Molded Gratings.

Ferrotech’s FRP Gratings are manufactured by interlacing unsaturated polyester or phenolic resin matrix with fiberglass roving as reinforcing material. Gratings produced by this technique yield a product having excellent corrosion resistance.

FRP Molded Gratings:

FRP Molded Gratings are manufactured by thermally curing reinforcing glass-fibers and polyester resin in a single mold and are cast integrally by heating and compressing. It is composed of a certain number of symmetrical lattices with loading properties in both lengths and with directions.

  • Height (mm) – 25, 30, 38, 50
  • Mesh (mm) – 25x 100, 38 x 38, 50 x 50
  • Bar thickness (mm) – 6.35, 7-5, 8-5
  • Open Rate (%) – 68, 69, 71
  • Sheet Sizes (mm) – 1000 x 3000, 1000 x 4000, 1220 x 3660 & 1220 x 4000

FRP Pultruded Gratings:

FRP Pultruded Gratings are made by assembling FRP Pultrusions Which are manufactured with a high percentage of glass fiber roving soaked with resin and finally designed to desired shapes by heating and pultrusion.

Pultrusions are a continuous process in which the glass fibers, glass matting a synthetic surface veil are literally “Pulled” simultaneously through a polyester or Vinylester resin bath. The desired geometric shape is formed as they are pulled through a heated steel die and as the composite hardens.

Ferrotech’ s FRP molded gratings are available in the main types of resin: orthophthalic, isophthalic, Vinylester and Phenolic; fire-resistant and low smoke emission formulations can be formulated (M1-F0, M1-F1, ASTM E 84, BS part 7, ASTM F3059-15 L2, IMO MED, etc.)
