FRP / GRP Molded Gratings

Molded Gratings

Saudigrate molded gratings are manufactured with continuous pre-tensioned and pre-impregnated glass fiber roving strands, thoroughly wetted with a chemical resistant polyester, interwoven between each other forming a one-piece structure by means of an exclusive mechanized processor.

Uniqueness of FRP/GRP

Corrosion Resistance

Saudigrate FRP/GRP gratings offer superior corrosion resistance. It can effectively resist the corrosion of acids, alkali, organic solvents and salts. FRP/GRP gratings don't rust when contacted by chemicals because no electrochemical action could occur over the grating. It serves as an ideal substitute for metal, wood or concrete.

Strength‐weight ratio

FRP/GRP gratings are a low-density composite of resin and fiberglass. Their third density is only 1/4 of steel, 2/3 of aluminum but almost as strong as ordinary steel. It is also light in weight and allows easy transportation and hassle‐free installation.

Fire Retardant

All Saudigrate FRP/GRP gratings are designed to exhibit a minimum of Class1 flame spread rating in accordance with ASTM E‐84. Our FRP/GRP gratings are available in a variety of resins offering an array of flame spread rating and smoke densities from as low as 5 flame spread rating and 5 in smoke density.

Impact resistance

FRP/GRP gratings have a high impact strength allowing repeated bending without any permanent deformation. Its moderate elasticity allows people to feel comfortable when standing over the gratings for a long period of time.

Anti‐slip / UV protection

FRP/GRP gratings offer superior slip resistance compared to conventional steel gratings. They are available in either concave meniscus surface or gritted surface. Both types provide excellent anti‐slip function. It decreases the risk of slipping accidents. Also, FRP/GRP gratings are not affected by the sun’s harmful ultra‐violet rays.

Closed Type Gratings

Saudigrate: closed panel

Manufactured in a single operation during the molding process, with the same load-bearing structure as the open gratings, the SAUDIGRATE closed panel is mostly used to cover trenches, vats or areas where it is necessary to prevent objects falling and dripping of liquids underneath.

Closing

Structured with layers of interwoven glass fibers (woven glass cloth/CSM) and with integrated anti-skid surface (pure integrated silica grains). Classified R13-V10 according to DIN 51130 norm.

Thickness

The thickness of the closing layer may vary from 3 up to 8 mm according to the requirements. Closed panels can be manufactured also in a "sandwich" version (closing layers on both surfaces), increasing the mechanical resistance properties.
