FRP-Gratings

The many years of positive experience with the use of FRP gratings, not only in the industrial sector but also in the public and private sectors, have proven the benefits of FRP material in a variety of locations and situations. Since the late 90s, FRP products have been a permanent part of the Lichtgitter range.

  • high weathering and corrosion resistance

  • high chemical resistance

  • relatively low weight

  • quick and easy installation on site

  • long service life

  • electrically non-conductive

  • hygienic and resistant to bacteria

  • coloring possible (in many RAL colors)

Models/ Types
Standard Resin Systems
IFR

Premium grade Isophthalic Polyester resin systems with Class 1 fire retardancy per ASTM E-84 and excellent corrosion resistance. Meets USDA standards for incidental food contact. Available in green, yellow, dark gray and light gray.

VEFR

Vinylester resin system with Class 1 fire retardancy, per ASTM E-84. For maximum corrosion resistance in Lichtgrid standard resin systems, specify VEFR. Available in red and dark gray.
(Other resin systems and colors are available on special order. All Lichtgrid resin systems incorporate an ultraviolet (UV) inhibitor.)

Open Molded Grating

Molded fiberglass grating is a one-piece grating made of reinforced polyester or vinylester (FRP). It is available in standard panels and sizes. FRP grating is manufactured by interweaving continuous, thoroughly wetted fiberglass roving with thermosetting resin systems.

The components resin, fiberglass, additives and dyes are the basis of the composite FRP, which is very versatile in its form and practicability. The resin used determines the chemical resistance, flexibility and UV resistance of the FRP product. Depending on the application, different types of resins are used. FRP products can be made from orthophthalic resin, isophthalic and vinylester resin (with extremely high chemical load), Lichtgitter uses isophthalic resin as standard. The special feature of the phenolic resin is the high fire resistance and very low smoke production.
As a reinforcement, continuous glass filaments are woven in a plurality of layers. Additives such as flame retardants, hardeners, accelerators and UV stabilizers are further components. The standard color of the Lichtgitter FRP gratings is gray, similar to RAL 7035. Color pigments allow coloring of the FRP product. This results in various architectural design options or warning and signal designations.

The numerous possible applications include floor systems, walkways, work platforms, stairs, ramps, trench covers and catwalks. There are plenty of industries that fiberglass-gratings can be used in, for example oil/gas, mining/smelting/refining, food processing, beverage, chemical processing, water and wastewater treatment, metal finishing, pulp/paper, transportation, pharmaceutical and textile.

Standard Panel Sizes
Pultruded Grating

Pultruded grating is manufactured by continuously molding a synthetic surface veil and glass roving and matting by “pulling” simultaneously through a flame-retardant polyester or vinylester resin bath. The desired grating shapes are formed and solidified by being pulled through a heated steel die. Lichtgrid pultruded grating stands out in its strength, corrosion resistance and structural integrity.

Standard Panel Sizes
FRP Stair Treads

You can cut your own stair treads from Lichtgrid Stair Tread panels.


Easy cutting – inexpensive, accurate and quick thanks to cutting slots every six inches, which result in banded treads on both ends.

Economical – less wastage and less cost since the panel size 24-1/4” x 144” offers numerous combinations to maximize the number of treads.


Lichtgitter Fiberglass Stair Tread Covers provide an improved stairway-safety while being very cost-effective. They consist of corrosion resistant resin with a flow flame spread rating. An integral grit top surface and a woven fiberglass mat are the components of the panels.
