1800.711.4939www.directmetals.comFiberglass Grating ProductsMOLDED FIBERGLASS GRATINGMolded fiberglass grating is a fiberglass-reinforced plastic (FRP) thatcombines fiberglass rovings with thermosetting resins to form a strong, one-piece molded panel. A 65%/35% resin to glass weight ratio provides high corrosion resistance. Meniscus surfaces or applied grit surfaces provide slip resistance when compared to other flooring products. This product is best suited for corrosive environments.PULTRUDED FIBERGLASS GRATINGPultruded fiberglass grating is made using premium grade isophthalic polyester, vinyl ester, or phenolic resin systems with a synthetic surfacing veil, making it corrosion resistant, lightweight, and durable. Pultruded fiberglass has a grit surface for safety and a greater strength to weight ratio than molded fiberglass grating. A 35%/65% resin to glass ratio provides greater strength and less corrosion resistance than molded fiberglass. This product is best suited for longer spans.FIBERGLASS COVERED GRATINGOur fiberglass covered grating is a long-lasting, molded fiberglass floor product that combines smooth, gritted, or checker plate and molded grating manufactured with any of our resin systems. It is the ideal choice when a 100% covered flooring surface is needed. Our fiberglass covered grating is often used in loading and storage areas with high foot and cart traffic, where a strong, level surface is ideal. It offers approximately 50% higher stiffness values than that of open mesh grating, and its standard grit-top cover assures secure footing.BULLET RESISTANT FIBERGLASS PLATEOur bullet resistant fiberglass plate offers superior ballistic resistance at a weight less than 25% than that of a comparable steel panel. Now available for commercial security applications for your business, home or governmental facility, these fiberglass panels offer ballistic resistant security with the additional performance advantages of durability, corrosion resistance, electrical non-conductivity, low thermal conductivity and light weight.HEAVY DUTY FIBERGLASS GRATINGOur heavy duty fiberglass grating is available in both molded andpultruded grating systems. Both are designed to carry forklift andtractor-trailer loads that traditional molded and pultruded FRP grating products are not designed to support. Heavy duty fiberglass grating provides greater durability for higher volume traffic areas as well. Additionally, Heavy Duty Fiberglass Grating can be used to free span longer distances than traditional fiberglass grating.CUSTOM MATCHED COLORS AVAILABLEWill match to any RAL color.FIBERGLASS STAIR TREADS & STAIR TREADCOVERSLightweight and easy to install, fiberglass stair treads are available in both molded and pultruded types to match the fiberglass floor grating platforms. Fiberglass stair tread covers are made from a molded glass and resin system that is corrosion and impact resistant, fire retardant, and non-conductive. They provide a cost effective, slip-resistant protective surface for concrete, metal, and wood steps.FIBERGLASS GRATING HANDRAILS ANDLADDERSFiberglass handrail systems are fabricated from pultruded fiberglass components and molded thermoplastic connectors. Our modular fiberglass grating handrail systems are available in 2" square or 2" round configurations that are easy to grip, making them ideal for any high traffic area. Our fiberglass ladders and cages can be installed in a variety of applications from sumps to tanks, buildings, piers, portable equipment, etc., providing years of strength and dependability.FIBERGLASS ATTACHMENTS AND CLIPSOur fiberglass grating attachments and clips are specially designed to secure fiberglass grating or plates to the supporting structures.Additionally, they are used to fasten together adjacent grating panels, which minimizes load-induced differential deflection. All fiberglass attachments and clips are made of Type 316 stainless steel and are available in 1", 1-1/2" and 2" sizes.FIBERGLASS PLATESFiberglass plates feature a non-conductive surface that makes them an economical and safe solution to walking surfaces. In caustic and/or acidic conditions, fiberglass plates provide a level of corrosion resistance that is unequaled and more cost effective than stainless steel. Fiberglass plate is available with a non-grit surface or with a grit surface where anti-slip traction is needed.FIBERGLASS STRUCTURAL SHAPESOur fiberglass structural shapes and pultruded fiberglass profiles are made from a combination of fiberglass and thermosetting resin systems. All shapes are lightweight, impact resistant, low maintenance, non-magnetic, low conductive, and have dimensional stability, making them easy to install and ideal for several applications. Custom shapes are available upon request.Our pultruded grating inventoryFIBERGLASS

This advanced grating is also lightweight and easy to fabricate, 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 steel. Combining it’s low cost of installation with maintenance-free long-life, it is manufactured with a recessed tie bar configuration and an inherent resiliency, which reduces back and leg strain and contributes to ergonomics and worker productivity.CORROSION RESISTANCE - based on the use of premium grade, isophthalic polyester or vinyl ester resin systems and a synthetic surfacing veil.EASILY FABRICATED - no need for lifting equipment or expensive tools; can be easily carried by two workers and cut using standard circular or saber saws fitted with carbide blades.ELECTRICALLY AND THERMALLY NON-CONDUCTIVE - providing additional worker safety.ELECTRONICALLY TRANSPARENT - does not affect electromagnetic or radio wave frequencies.walkways, our pedestrian floor grating is ideal for any application where a corrosion-resistant, durable, lightweight surface material is required. Our pedestrian grating is available in 1" and 1-1/2" depths and in several configurations and panel sizes. 1" deep pedestrian grating is designed for access areas and walkways where pedestrian traffic is the heaviest load. 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 deflection criteria are required.

Molded fiberglass stair treads are 1-1/2" deep while pultruded can be 1", 1-1/2" and 2" deep. Safety and durability are just two of the outstanding features that make fiberglass stair treads and stair tread covers preferredcomponents for stairs and landings. 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 COVERSStair tread covers are made from a molded polyester mat that is corrosion and impactresistant, fire retardant and non-conductive. They come in 8", 9", 10", 11" and 12" depths, with a standard thickness of 1/8" with 1/4" thick covers available for heavy duty applications. Standard 12' panels are easily cut to size during installation or areavailable precut to custom lengths. Fiberglass stair tread covers have a durablealuminum oxide grit surface, which increases the safety of stairways and protectsexposed edges that are prone to chipping and cracking.
