GATORGRATE™ - OPEN MOLDED FRP GRATING

open molded grating GatorGrate® is a one-piece, reinforced polyester or
vinylester (FRP) grating, available in standard panels
and sizes. It is manufactured by interweaving
continuous, thoroughly wetted, fiberglass strand with
thermosetting resin systems. Standard panels are
available in four resin systems, two top surface
configurations, four panel sizes and five standard grid
patterns. Typical applications include floor systems,
walkways, work platforms, stairs, ramps, trench
covers and catwalks. GatorGrate has been
successfully used in many industries - including food
processing, beverage, chemical processing, water
& wastewater treatment, metal finishing, pulp/paper,
transportation, pharmaceutical, textile, oil/gas and
mining/smelting/refining.
open molded grating Standard Resin Systems
Standard GatorGrate resin systems are made
from premium grade resins. The three standard
resin systems are:
open molded grating
PFR: Polyester resin system with Class 1 fire
retardancy, per ASTM E-84. Moderate
corrosion resistance.
IFR - Premium grade Isophthalic Polyester resin system with Class 1 fire
retardancy, per ASTM E-84. Excellent corrosion resistance.
PFR & IFR Resin systems meet USDA standards for incidental food contact.
Available Colors For PFR & IFR are green, yellow, dark gray, & light gray.
VFR - Vinyl Ester resin system with Class 1 fire retardancy, per
ASTM E-84. For maximum corrosion resistance in Our standard
resin systems, specify VFR.
Available colors: orange & dark gray.
Other resin systems and colors are available on special order.
All GatorGrate resin systems incorporate an ultraviolet (UV) inhibitor.
Standard Grid Patterns
GatorGrate molded grating is available in five
standard grid patterns. Grid dimensions are
center line to center line.

Load & Deflection Data
The Load and Deflection Data provided in these tables are intended for guidance only, to help you determine the proper grating size
for your application. The use of different resin systems and top surface options can produce variations up to 15% in these values.
Because the product will be used in environments and under operating conditions that are not within our control, we cannot
guarantee the performance of the grating.
FRP products have low modulus of elasticity but high tensile strength, therefore loads are generally limited to the allowable deflection
determined by the end user. The following data are based on tests utilizing panels supported on two sides only. Additional stiffness
can be achieved by using cross supports.
