DURADEK® is a standard product stocked by distributors nationwide. DURADEK® 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 or vinyl ester resin. DURADEK® bearing bars are assembled into 12 panel sizes: 3-, 4-, and 5- foot widths in each of 8-, 10-, 12- and 20-foot lengths. Standard DURADEK® panels come with cross-rod spacings of 6" or optional 12" on center.
DURADEK® and DURAGRID® grating systems are designed to accommodate a wide variety of applications, such as:
|DURADEK® PULTRUDED GRATING||VS.||STEEL GRATING|
|STRENGTH||DURADEK® I-6000, 1-1/2"
48" Span, Ultimate Load = 2032 PSF
DURADEK® has a higher ultimate load carrying capacity.
|3/16" x 1-1/2" Bar, 1-3/16" o.c.
48" Span, Ultimate Load = 1,160 PSF
|WEIGHT||DURADEK® I-6000, 1-1/2" 3.3 PSF||3/16" x 1-1/2" Bar, 1-3/16" o.c. 11.0 PSF|
|IMPACT RESISTANCE||Glass mat in DURADEK® grating Distributes impact load to prevent surface damage even under sub-zero temperatures. Will not permanently deform. Stays flat for the life of the product.||Will permanently deform under impact. Takes a permanent set (dishing) in trench applications due to overloading.|
|CORROSION RESISTANCE||DURADEK®, with its polyester resin, is corrosion resistant to a broad range of acids, caustics and salts. Requires no painting or galvanizing.||Will rust even from water. Can cause galvanic corrosion. Requires painting or galvanizing for many applications.|
|SAFETY||DURADEK® has a round silica grit bonded to the surface of bearing bars for non-skid safety. Low electrical conductivity.||Non-serrated bars are not skid resistant or only skid resistant in one direction. Grounding potential around electrical equipment.|
|VERSATILITY||DURADEK® can be purchased in a safety yellow or gray with the resin pigmented throughout the bar. No painting required.||Grating must be painted for color. To maintain color and corrosion resistance, repainting may be required.|
|EASY FIELD FABRICATION||DURADEK® can be field fabricated with simple carpenter tools, is easy to cut and is much easier to move and place because it is lightweight.||Requires special blades, torch, harder to cut. Requires lifting equipment to move and place.|
|BANDING||DURADEK® is an I-bar that does not leave a sharp edge when cut. The bars will not bend or deform in the lateral direction; therefore, DURADEK® does not need to be banded.||Cutting a rectangular steel bar leaves sharp edges. The flat bars will bend and deform in the lateral direction; therefore, steel should be banded.|
