DURADEK® is our standard pultruded grating product. It is
available with individual bearing bars in either 1" or 1-1/2" "I"
shapes or a 2" "T" shape. DURADEK® is a flame retardant product utilizing a
polyester resin. The bearing bars use both longitudinal (glass roving) and
multidirectional (glass mat) reinforcements as well as a synthetic surfacing
veil to provide unequaled corrosion resistance.
DURAGRID® custom grid
or grating systems are designed to accommodate specific applications that
cannot effectively be met by a standard fiberglass grating. DURAGRID® offers
the customer options such as selection of open space, bar shape, cross-rod
placement, custom fabrication, custom resin or color.
DURAGRID® Heavy Duty
fiberglass grating is a pultruded bar type grating that can be designed and
used like traditional metal grates. The solid individual bearing bars are
designed to take heavy wheel traffic such as fork lifts, tow motors and
truck traffic. Heavy duty grating is constructed of the same type composite
used in the other DURAGRID® products.
DURAGRID® Phenolic Grating
is a dramatic innovation for markets where fire safety is a major concern;
offering superior resistance to flame and high temperature with low smoke
and toxic fume emissions. The nonflammable nature of phenolics enable
phenolic grating to withstand higher temperatures than polyester or vinyl
ester for extended periods of time without major structural damage. Combined
with low thermal conductivity, this provides fire protection not available
with alternate materials. DURAGRID® Phenolic Grating is the first composite
grating to receive U.S. Coast Guard approval! It is accepted for use in
locations and applications as allowed in the U.S.C.G. Policy File Memorandum
2-98 for fire retardant grating meeting structural fire integrity Level
Many features of pultruded grating that are
critical to industrial applications, have been compared on a point-for-point
basis to molded, aluminum and steel gratings. To see this comparison

Complete load tables and properties are shown
in the product literature and can be ordered from the
Literature Library. The bearing bars are assembled into 12 panel sizes
for your convenience; 3-, 4- and 5-foot widths in each of 8-, 10-, 12- and
20-foot lengths. Standard panels come with cross-rod spacings of 6" or
optional 12" on center.
DURADEK® and DURAGRID® gratings are
lightweight and, therefore, easily handled in installation, and cost less to
ship than steel grating. A patented 3-piece cross-rod system mechanically
locks and chemically bonds the cross-rods to the web of each bearing bar.
This separates and affixes bearing bars firmly in position and distributes
concentrated loads to adjacent bars. The system allows DURADEK® and DURAGRID®
grating to be cut and fabricated like a solid sheet.
Standard carpenter's tools with abrasive
cutting edges may be used; just coat the cut ends with resin sealer and
install. You may request the detailed Field Fabrication Guide from
