Fiberglass 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 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 2(L2).

How Strongwell Pultruded Grating is Made

Designing with Pultruded Fiberglass Grating

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.
 

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 may request the detailed Field Fabrication Guide from 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.
 

Accessories

A complete line of accessories is available for installing DURADEK® and DURAGRID®, including stair treads and landings, panel hold-downs, panel connectors and curb angle.
 

Availability

Standard yellow and gray polyester panels can be shipped from the factory within 72 hours. Distributors stock DURADEK® in major cities throughout the USA and Canada.
