GATORDECK™ - PULTRUDED GRATING
Pultrusion is a continuous molding process in which glass
roving, glass matting, and a synthetic surface veil are
literally “pulled” simultaneously through a flame-
retardant polyester or vinylester resin bath. Desired
geometric shapes are formed and solidified as they
are pulled through a heated steel die. Our Gator-
Deck® pultruded grating provides the ultimate
combination of strength, corrosion resistance, and
structural integrity as a result of the automated
pultrusion process.		 pultruded grating

STANDARD RESIN SYSTEMS
WIDTH X LENGTH
Standard Resins meet ASTM E-84 Class 1 flame
rating, and include UV inhibitors for applications
involving continuous exposure to the sun. Choose from
the following standard resin systems. Or, call us about
creating special resins for unique environments, such as
low smoke, low toxicity, or extra low flame applications.
IFR - Made with a premium-grade isophthalic
polyester flame-retardant resin system. Standard colors
are yellow and gray for pultruded grating. WT grating
and one inch I-bar grating are also available in white.
VFR - Made with a premium-grade vinylester flame-
retardant resin system for added protection against
corrosion. Standard colors are yellow and gray for
pultruded grating.
Grating sizes are specified using width (cross-rod
dimension) and length (bearing bar dimension)

Values tabled are for design selection and are approximate. We recommend selecting gratings based on a deflection of .25-inch or less.
This deflection may be exceeded at the discretion of the designer. Deflections of .25-inch or less will give excellent pedestrian comfort.
Deflections of .375-inch or less will give satisfactory pedestrian comfort. Loads for short spans in the .250 and .375 deflection columns
have been omitted to allow for shear properties.

Values tabled are for design selection and are approximate. We recommend selecting gratings based on a deflection of .25-inch or less.
This deflection may be exceeded at the discretion of the designer. Deflections of .25-inch or less will give excellent pedestrian comfort.
Deflections of .375-inch or less will give satisfactory pedestrian comfort. Loads for short spans in the .250 and .375 deflection columns
have been omitted to allow for shear properties.
