DURAGRID® Phenolic grating is a dramatic innovation for markets where fire safety is a major concern; it offers superior resistance to flame and high temperature with low emissions of smoke and toxic fumes. 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 was 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 2(L2).

3-Piece Cross-Rod System
Strongwell’s 3-piece cross-rod system is the best assembly method for pultruded grating in the fiberglass grating industry because it provides better stability than competitive crossrod systems. The three piece members in combination with Strongwell’s proprietary bonding method tie the bearing bars together and provide stability to the grating panel. This system makes Strongwell’s pultruded grating the superior choice in the marketplace.
DURAGRID® custom grid and 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 bar spacing (which creates varying open space in the grating or grid), bar shape, cross-rod placement, custom fabrication, custom resin or color.
Designing with Pultruded Fiberglass Grating
Complete load tables and properties can be found under the Technical Information tab or in the Fiberglass Grating Brochure found under the Product Literature page of the site. 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 will find the detailed Field Fabrication Guide under the Literature tab at the top of this page. You may also request that a copy be mailed to you by visiting the Literature Library.
Strongwell has released a Decking Fasteners flyer that provides information on the preferred fasteners available for all Strongwell decking products. Illustrations of the various fasteners and uses are exhibited on the back of the flyer.
