Molded FRP Grating for Platforms, Walkways, Flooring

Molded fiberglass grating combines fiberglass rovings with thermosetting resin system to form a solid, one-piece molded panel. It is available in square and rectangular mesh with smooth surface, or standard concave and optional grit top surfaces. Molded fiberglass grating offers superior tensile strength, corrosion resistance, light weight and extended life. It also provides a cost effective solution and long lasting performance for many industrial and recreational applications.

There are six pieces of fiberglass molded gratings on the ground, and they concentrate all types of gratings.
MFG-01: We offer molded fiberglass gratings with square mesh or rectangular mesh, available in smooth, concave, grit surfaces and covered type.
There are two pieces of round molded FRP gratings with same sizes on the ground.
MFG-02: Round molded fiberglass gratings are also available and custom size is made upon request.
It shows one molded fiberglass grating with rectangular mesh, it has translucent green colour.
MFG-03: No colour pigments are added in the production of translucent FRP gratings.

MFG-04: Custom fabricated product - molded FRP grating in blue.

Key features of molded fiberglass grating

  • Good corrosion resistance
    Molded fiberglass grating is manufactured with continuous fiberglass strands wetted thoroughly with premium grade thermosetting resin system, which ensures excellent corrosion resistance.
  • High strength to weight ratio
    Molded FRP grating weighs much less than metallic grating, but it has great tensile strength as the continuous fiberglass strand alternating layers and ultimate one-piece construction distributes loads to bi-directional bars.
  • Non-conductive electrically and thermally
    Molded grating, ideally designed for electrically hazardous locations, has inherent properties that reduce the risk of electrical shock being an insulator between conductive materials.
  • Slip resistance
    The built-in concave surface and grit surface provide excellent slip resistance and offer adequate protection for most applications.
  • Easy installation & fabrication
    Molded fiberglass grating weighs about one fourth that of traditional metal grating, which makes installation and fabrication easy.
  • Cost effectiveness
    FRP grating allows for easy on-site cutting, minimizing cost and waste. In addition, its inherent ultraviolet resistance feature and corrosion resistance property make it a maintenance free option to metallic grating.
  • Long service life
    Our molded fiberglass grating are all made to meet the highest international standards. The coated resin surface increases resistance to chemical corrosion and continuous UV exposure, which prolongs its service life.

Surface options

  • Concave/Meniscus surface
    It has a shape of a natural crescent moon which provides superior slip resistant footing in most environments including wet or oily conditions. It is the standard surface for molded fiberglass grating.
  • Flat surface
    Flat surface is suitable for building fences around electrical plants, in sunshade system or as a space divider.
  • Gritted surface
    The gritted surface could be applied to panels for enhanced safety. It is impregnated into the mold, which does not flake off and offers the best anti-skid surface.
  • Closed surface
    With this kind of surface, you can have a gritted plate or checkered plate at the anti-skid surface. It is ideally used to prevent liquid leakages and gas volatilization.

Resin system

Made from premium grade resins, the two standard resin systems are:

  • Polyester
  • Vinyl ester

Both of them provide superior and reliable performance in corrosive environments.


  • Standard colours: yellow, dark gray, light gray, green, red.
  • Common panel sizes: 3' × 10', 4' × 8', 4' × 12', 5' × 10'.
  • Common thickness: 0.5", 1", 1.5", 2".
