36www.directmetals.com800.711.4939Pultruded GratingAll of our pultruded gratings are manufactured with a high percentage of glass within the laminate, providing durability, extremely high unidirectional strength, and stiffness. Due to its exceptional stiffness, it can be used with condence in applications where wide support spans are required. For most applications, it is used to replace corroding steel grating. Our pultruded grating rarely requires additional support.Designed specically for pedestrian walkways, our pedestrian oor grating is ideal for any application where acorrosion-resistant, durable, lightweight surface material is required. Our pedestrian grating is available in 1" and 1-1/2" depths and in several congurations and panel sizes. 1" deep pedestrian grating is designed for access areas and walkways where pedestrian trafc is heaviest. 1-1/2" pedestrian grating is approximately three times stiffer than the 1" deep version and is used for applications where wider spans (up to 72") or lower deection criteria are required.To form a pultruded element, continuous ber rovings and mat are mechanically drawn through a resin bath and shaped through a series of forming guides, then pulled through a heated die.LIGHTWEIGHT YET DURABLE - less than one-half the weight of steel grating,allowing easy removal for access below oor level and installation with no heavy equipment and less manpower required.ADDED SAFETY - durable grit surface,permanently bonded, and baked to thegrating surface for a safe and slip-resistant walkway.FIRE RETARDANT - ame spread rating of 25 or less, according to ASTM E-84; meets the self-extinguishing requirements of ASTM D-635.MAINTENANCE FREE - corrosion resis-tant and requires no scraping, sandblast-ing or painting; install it and forget it.UV PROTECTION - UV inhibitors included in the resin formulation, along with a sur-facing veil and grit top surface for optimum protection from the effects of weathering.EASILY FABRICATED - no need forlifting equipment or expensive tools; can be easily carried by two workers and cut using standard circular or saber sawstted with carbide blades.ELECTRICALLY AND THERMALLY NON-CONDUCTIVE - providing additionalworker safety.ELECTRONICALLY TRANSPARENT - does not affect electromagnetic or radio wave frequencies.Combining corrosion resistance, long life, and a maintenance-free design, ourpultruded grating is superior toconventional metals. This advancedgrating is also lightweight and easy tofabricate, making it less expensive to install. In fact, the savings on labor and equipment often make the total installed cost of our pultruded grating comparable to that of steel. Combining it’s low cost of installation with maintenance-free long-life, it is manufactured with a recessed tie bar conguration and an inherent resiliency, which reduces back and leg strain and contributes to ergonomics and workerproductivity.FEATURES AND BENEFITSCORROSION RESISTANCE - based on the use of premium grade, isophthalic polyester or vinyl ester resin systems and a synthetic surfacing veil.

Maximum pedestrian safety is provided by the anti-slip walking surface. Fiberglass stair nosings form a highly visible and durable edge at the primary point of contact on stairs and landings. Fiberglass stair treads and stair tread covers provide a cost-effective, slip-resistant protective surface for concrete, metal, and wood steps.Stair tread covers are made from a molded polyester mat that is corrosion and impact resistant, re retardant, and non-conductive. Stair treads come in 8", 9", 10", 11", and 12" depths with a standard thickness of 1/8 inch with 1/4-inch thick covers available for heavy duty applications. Standard 12-foot stair treads are easily cut to size during installation or are available precut to custom lengths.Fiberglass stair tread covers have a durable aluminum oxide grit surface, which increases the safety of stairways and protects exposed edges that are prone to chipping and cracking.Lightweight and easy to install, industrial grade berglass stair treads are available in 1-inch and 1-1/2-inch deep “I” bar structural proles with a variable open area of 40%, 50%, or 60%. We also carry 2-inch deep “T” bar structural proles with 33% or 50% open area. Stair tread covers are black or dark gray with highly visible yellow nosings, and are available in 9- and 10-inch widths by 12-foot lengths.

40www.directmetals.com800.711.4939Pultruded Grating Resin SystemsOur ASTM E84 pultruded grating is available in two resin formulations for an accurate match of product characteristics with the application. Both resin systems provide corrosion resistance that is superior to that offered by metal grating.IFR-25 - This isophthalic polyester resin formulation provides a low ame spread rating of 25 or less, and is designed for applicationswhere there is moderate exposure to corrosive elements.VFR-25 - With a ame spread of 25 or less, this vinyl ester resin system provides dependable resistance to both acidic and alkalineenvironments.CLIP ASSEMBLIES FOR MOLDED GRATINGWe offer specially designed attachments and clips, both to fasten panels together and to secure them to support structures. All types are made of Type 316 Stainless Steel, and are available in 1", 1-1/2" and 2" sizes.
