1800.711.4939www.directmetals.comSAFETY GRATINGEvery year, industrial accidents such as falls, tripping over debris, and slipping on wet or greasy surfaces cost millions of dollars in lost man hours and products. By reducingaccidents, insurance costs can frequently be decreased. Grip Strut Safety Grating helpsreduce accident rates by providing a safer walking/working surface than any other available grating product. Its serrated surface gives maximum slip protection and performance underpractically all conditions and in every direction.The serrated surface is designed in an open diamond pattern. This allows the drainage offluids, mud, chips, and other accident-causing debris. With 4-½" high side channels, Grip Strut Safety Grating Walkways meet OSHA requirements for toeboards on elevated structures. SAFER, SERRATED SURFACEThe serrated surface grips soles securely in all directions – in practically every place. These non-slip Grip Strut Grating surfaces are ideal for inside or outside locations where mud, ice, snow, oil, and detergents can create hazardous walking conditions. Openings are small enough to catch most falling tools and other dangerous objects.FAST INSTALLATIONLight, easy-to-handle planks make installation simpler, quicker, and can be handled by one man. Most sections are rapidly bolted, clamped, or welded into place and easily field-cut at virtually any angle or fabricated to adapt to field conditions. Several attachment devicespermit fastening to most existing surfaces, allowing for fast installation or disassembly.SERRATED GRIP STRUT™ GRATINGOffers excellent slip resistance wherever maximum safety underfoot is essential. Material meets anti-slip values outlined in Federal Specification RR-G-1602A.NON-SERRATED GRIP STRUT™ GRATINGFor all-purpose use where a high degree of slip resistance is required with a smoothertexture and design. Product availability is subject to extended lead time.STANDARD GRIP STRUT™ GRATING PLANKSAvailable in materials and sized to meet most load span requirements. May be used as is or banded, cut, welded, or punched to suit your requirements.GRIP STRUT™

BAR GRATING28www.directmetals.com800.711.4939Aluminum Plank GratingAluminum Swaged GratingALUMINUM RIVETEDA type of aluminum grating which combines straight bearing bars and bent connecting bars riveted together at their contact points. Riveted grating, although being the oldest style of industrial footwalk, is still the choice of many engi-neers due to its reliability and durability. All popular sizes and spacings of riveted grating are available. ALUMINUM PLANKA type ofextruded grat-ing which is available in 6" wide sections and either plain sided or Interlocking. Plank can be provided in sections up to 26' 0" in length or fabricated per plans and specs. Plank grating is available unpun-ched as an economical and structurally su-perior substitute for aluminum checkerplate or with a variety of punch/patterns. ALUMINUM PRODUCTSALUMINUM FLUSH TOP A type of pres-sure-locked grating in which the cross bars are in the same plane relative to the top surface of the grating. Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4” increments. Bearing bar spacing of 13/16", 15/16", 11/16", and 7/16" c.c. and cross bar spacing of 4" or 2" are available. Where skid resistance is de-sired, a serrated surface can be provided. ALUMINUM RECTANGULAR BARA type ofpressure-lockedgrating madebypermanentlyattaching cross bars to bearing bars through a pressure-applied swaging process. Bear-ing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" increments. Bearing bar spacing of 13/16", 15/16", 11/16", and 7/16" c.c., with cross bar spacing of 4" or 2" available. Where skid resistance is desired, a serrated surface can be provided. ALUMINUM I-BARA type of pressure locked grating which utilizes an “I” shaped bearing bar ranging in size from 1" x 1/4" through2-1/2" x1/4" in 1/4" increments. Bearing bar spacing of 13/16" and 15/16" c.c. and cross bar spacings of 4" or 2" are available. The I-Bar design takes advan-tage of the aluminum extrusion process by placing the metal where it is most effective, at the outermost fiber while reducing the thickness of the neutral axis web. This de-sign consideration allows the same load carrying capacity at less weight per square foot than rectangular bar therefore result-ing in a cost savings.ALUMINUM FLUSH TOP GRATINGAluminum Flush Top grating combines the sure lock reliability of swage-locked grating with the cosmetic appeal and addedwalking surface of traditional pressure locked grating. Best of all, by takingadvantage of the swage-lock manufacturing process, aluminum flush top grating offers a cost savings over traditional pressure locked grating while at the same time allowing banding to be an option rather than arequirement. Field cutting is also possible. ALUMINUM RECTANGULAR ORI-BAR GRATINGThese two grating designs utilize a process by which 1/4" or 5/16" square cross bars are assembled through punched, diamond shaped holes in the bearing bars and then secured by swaging to prevent turning,twisting, or loosening. Available with either rectangular or l-shaped Bearing Barsections, this manufacturing process offers the economy of cutting individual pieces from panels, enables field alteration ofgrating panels and allows banding as an option rather than as a requirement. PRESSURE LOCKINGThe most common method of manufactur-ing aluminum bar grating is through a process known as pressure locking.Pressure locked grating asdefined by the NAAMM Metal Bar Grat-ing Manual is “Grating in which the cross bars aremechanically locked to the bearing bars at their intersections bydeforming or swaging the metal.” Direct Metals® provides a permanently attached pressure locked joint which will give long lasting life under normal service conditions.

31800.711.4939www.directmetals.comBAR GRATINGAluminum Plank is structurally sound and cosmetically attractive. Plank grating is non-sparking, non-magnetic, non-skid, and relatively maintenance-free. It is durable, corrosion resistant, and possesses a high strength-to-weight ratio. The surface can be unpunched or with various punches/pat-terns for the passage of air, light, heat, and moisture. The interconnecting webs offer a flush-top walking surface. Aluminum plank grating has found application in sewage and wastewater treatment plants, as well as in the marine refrigerator (reefer), freezers, and cargo-hold flooring market. Aluminum plank grating is available in five cross-sec-tional designs; Heavy Duty (plain sides), Heavy Duty (interlocking sides), Light Series (plain sides), Reefer (plain sides), and Reefer (interlocking sides)The Heavy Duty sections are usedprimarily in water and waste treatment and the marine markets, while the Light Series and Reefer sections are exclusively in marine refrigerator applications. Interlocking Heavy Duty, Reefer sections and edge sections are only available in 1” deep grating.Aluminum plank grating is available unpunched or with various punches/patterns, as shown below. Rectangular or square-punched holes are most commonly used for water and waste treatment plants and in marine applications, while round holes find applications primarily in the marine market. The surface of plank grating can be specified as plain or with one of two styles of upsets designed to promote a slip-resistant walkway, especially in the presence of moisture, oil, or other spilled substances.REEFER (Plain Sides)REEFER (Interlocking Sides)REEFER PUNCH/PATTERNAVAILABILITYHEAVY DUTY (Plain Sides)3/4"thru2-1/2"1.200"1.200"6”1" only1.500"6"3" FEMALE EDGE 3" MALE EDGE1" only1" only1.500"1.500"1.500"6"HEAVY DUTY (Interlocking Sides)LIGHT SERIES (Plain Sides)1.200"1.200"1.200"2.400"1.200"2-1/2" FEMALE EDGE 2-1/2" MALE EDGE1" only1" only1" only6"6"ALUMINUM PLANK SECTIONPLANK PUNCH / PATTERNADA Compliant

Cross Bars: Electroforge welded at right angles to bearing bars at 4" centers maximum. (Note: 2" cross bar centers may be specied at the discretion of the architect/engineer.) 4. Surface: Plain. (Note: A serrated surface may be specied for maximum skid resistance.) 5. Loading: Grating to carry a pedestrian loading equal to 100# per square foot over the required clear span with deection not to exceed 1/4". (Note: Alternate loading requirements may be specied at the discretion of the architect/engineer.) 6. Finish: Galvanized or manufacturer’s standard black paint at the discretion of the architect/engineer. 7. Fabrication and Tolerances: In accordance with the NAAMM Metal Bar Grating Manual. For those areas requiring the corrosionresistance of stainless steel, Direct Metals® stocks 1" x 3/16", 1-1/4" x 3/16" and1-1/2" x 3/16" 19-W-4 Type 304 stainless steel electroforge welded grating.

FIBERGLASS GRATING44www.directmetals.com800.711.4939FIBERGLASS PRODUCTSMOLDED FIBERGLASS GRATINGMolded fiberglass grating is a fiberglass-reinforced plastic (FRP) that combines fiberglass rovings with thermosetting resins to form a strong, one-piece molded panel. A 65%/35% resin to glass weight ratioprovides high corrosion resistance. Meniscus surfaces or applied grit surfaces provide slip resistance when compared to other flooringproducts. This product is better suited for corrosive environments.PULTRUDED FIBERGLASS GRATINGPultruded fiberglass grating is made using premium-gradeisophthalic polyester, vinyl ester, or phenolic resin systems with asynthetic 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 lesscorrosion resistance than molded fiberglass. This product is better suited for longer spans.FIBERGLASS COVERED GRATINGOur fiberglass covered grating is a long-lasting, molded fiberglass floor product that combines smooth, gritted, and checkered plate or molded manufactured with any of our resin systems. It is the ideal choice when 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 offersapproximately 50% higher stiffness value than 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% that of a comparable steel panel. Now available for commercial security applications for your business, home, or governmental facility, these fiberglass panels offer resistant security with the additional performance advantages of durability,corrosion resistance, electrical non-conductivity, low thermalconductivity, and lightweightHEAVY 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 FRPgrating 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 TREAD COVERSLightweight and easy to install, fiberglass stair treads are available in 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, 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 AND LADDERSFiberglass handrail systems are fabricated from pultruded fiberglass components and molded thermoplastic connectors. Our modularfiberglass grating handrail systems are available in 2" square or2" round configurations that are easy to grip, making them ideal for any high traffic area. Our fiberglass ladders and cages can beinstalled in a variety of applications from sumps to tanks, buildings, piers, portable equipment, etc., providing years of strength anddependability.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 gratingpanels, which minimizes load-induced differential deflection. Allfiberglass 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 corrosionresistance 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 resinsystems. All shapes are lightweight, impact resistant, lowmaintenance, non-magnetic, low conductive, and have dimensional stability, making them easy to install and ideal for severalapplications. Custom shapes are available upon request.Our Pultruded grating inventory
