Fiberglass

Grating

Why fiberglass?

Fiberglass grating provides excellent strength per weight ratio, and is ideal in high corrosive situations. With a variety of molded patterns, pultrusions, resin, and colors to choose from; fiberglass has something to cover any application.

If you are looking for alternate corrosive resistant material, please check out our Aluminum products.

For an alternate in heavy duty traffic rated grating check out our Steel products.

Read up on how we can take care of your entire fiberglass project with our Fiberglass Structure capabilities.

Molded Grating

Molded grating is engineered to provide proven corrosion resistance and reliable service under extreme

conditions. The interwoven square mesh construction provides bi-directional strength allowing for

efficient panel usage and cutting to minimize waste. The high resin to glass ratio (approximately

65% resin to 35% glass by weight) provides excellent service life in the most demanding

applications.  Molded grating is available in square or rectangular mesh patterns with either

Meniscus (Concave - no grit) or Gritted slip resistant top surfaces.

Standard Resin Systems
Molded grating is available in three standard resin systems each providing differing levels of corrosion protection.  

All three resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.

  • GP: a General Purpose Polyester Resin System offers good corrosion resistance at an economical price. Standard colors available: Green, Yellow, Dark Gray and Light Gray.

  • IFR: a premium grade Isophthalic Polyester Resin System that provides excellent corrosion protection.  Standard colors available: Green, Yellow, Dark Gray and Light Gray.

  • VFR: a Vinyl Ester Resin System provides the highest level of corrosion protection. Standard colors available: Dark Gray and Orange.

Pultruded Grating

Pultruded grating provides the capability to support heavier loads and longer spans when compared

to molded grating of similar depth and weight. We have an extensive offering of pultruded gratings

to meet most every need from ADA compliant walkways to heavy duty vehicular traffic conditions.

Pultruded gratings are engineered to withstand corrosive conditions that also require high strength.

Standard Resin Systems
Pultruded grating is available in two standard resin systems each providing differing levels of corrosion protection.  Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.

  • IFR: a premium grade Isophthalic Polyester Resin System that provides excellent corrosion protection.  Standard colors available: Yellow and Dark Gray.

  • VFR: a Vinyl Ester Resin System provides the highest level of corrosion protection.  Standard colors available: Yellow and Dark Gray.

Specialty Grating

Fiberglass grating comes in many styles and sizes for any project. Not every style is in-stock ready to go and must be made to order. Special spacings, depths, and resins can be requested from our list below.

High Load Capacity (HLC) grating makes use of of the traditional benefits of molded grating products; high strength, corrosion resistance, fire retardancy, nonconductivity and low maintenance, and has been engineered to carry the higher loads that  traditional grating products can not. Molded HLC grating is available in a 4’ x6’ panels with 1-1/2” and 2” thicknesses and comes in GPFR, IFR, and VFR resin systems.
