Pultruded grating is a versatile product! If standard DURADEK® grating doesn’t meet your needs, Strongwell can customize grating to your exact requirements by varying the bearing bar shape and spacing.

DURADEK® Standard Pultruded Grating DURADEK® is a standard pultruded grating product stocked by distributors nationwide. 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 or vinyl ester 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 Grating 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.

	DURAGRID® Heavy Duty Grating DURAGRID® Heavy Duty 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 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).

Extremely Strong Corrosion Resistant Impact Resistant Low Electrical and Thermal Conductivity Non-skid Surface Easily Fabricated in the Field

Fabrication 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.

	Surface Texture Grids can be ordered with or without an anti-skid grit surface. A variety of grit material and textures can be ordered.
