1800.711.4939www.directmetals.comSAFETY GRATINGDirect Metals® — Your Safety Grating Source featuringGrip Strut™Every year, industrial accidents including, falls, tripping over debris, and slipping on wet or greasy surfaces, cost millions ofdollars in lost man hours and production. Reducing accidents can reduce insurance costs. Grip Strut™ Safety Grating helps reduce accident rates by providing a safer walking and working surface than any other available grating product. Its serrated surface gives maximum slip protection and performance under practically all conditions and in any direction.The serrated surface is designed in an open diamond pattern. This allows for the drainage of uids, mud, chips and otheraccident-causing debris. With 4-1/2" 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 and in 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 and quicker. They can be handled by one man. Most sections are rapidly bolted, clamped or welded into place, easily eld-cut at virtually any angle or fabricated to adapt to eld conditions.Several attachment devices permit 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 set forth in Federal Specication RR-G-1602A.Non-serrated Grip Strut™ GratingFor an all-purpose use where a high degree of slip resistance is required with a smoother texture and design. Productavailability 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. General Load InformationHow to read load tablesTo select size of Grip Strut™ Safety Grating, determine load, clear span, and deection requirements, and select from the load tables the appropriate plank to meet your job requirements.EXAMPLE: Clear span of 4'-0" concentrated load requirement of 300 lb. at 0.25" max. deection.Allowable Uniform Load (U)Values indicated in the rows adjacent to “U” are the lowest of the (1) maximum allowable uniform loads consideringchannel exure and (2) maximum grating surface exure.Deection Corresponding to “U”Deection values are indicated below the uniform loads, and are the mid-span side channel deections for the planks carrying the allowable uniform loads (Figure 3).Allowable Concentrated Load (C)Values indicated in the rows labeled “C” are the lowest of the (1) maximum allowable concentrated load considering channel exure (Figure 2), with both channels effective and (2) the maximum allowable strut load (Cs) for a 1-ft. long sample (Figure 1).Deection Corresponding to “C”Deection values indicated below “C”values in the tables are the mid-span, side channel deections produced when theallowable concentrated load is placed at mid-span.

BAND - A at bar welded to the end of a grating panel or along the line of a cutout and extending neither above nor below the bearing bars. Load-Carrying Band: A band used in a cutout to transfer the load from unsupported bearing bars to the supported bearing bars. Trim Band: A band which carries no load but is used chiey to improve appearance. BEARING BARS - Load-carrying bars made from steel strip, slit sheet or rolled or extruded aluminum, and extending in thedirection of the grating span. BEARING BAR CENTERS - The distance center to center of the bearing bars. CARRIERS - Flats or angles, which are welded to the grating panel and nosing of a stair tread, and are bolted to a stair stringer to support the tread. CLEAR OPENING - The distance between faces of bearing bars in a rectangulargrating or between a bent connecting bar and a bearing bar in a riveted grating. CROSS BARS - The connecting bars made from steel strip, slit sheet, rolled bars, or rolled or extruded aluminum, which extend across the bearing bars, usually perpendicular to them.

PRESSURE-LOCKED GRATING - Grating in which the cross bars are mechanically locked to the bearing bars at their intersections by deforming orswaging the metal. RADIALLY CUT GRATING - Rectangular grating which is cut into panels shaped as annular segments for use in circular or annular areas. RETICULINE BAR - A sinuously bent connecting bar extending between two adjacent bearing bars, alternately contacting and being riveted to each. RIVET CENTERS - The distance center to center of rivets along one bearing bar. RIVETED GRATING - Grating composed of straight bearing bars and bent connecting bars, which are joined at their contact points by riveting. SERRATED GRATING - Grating which has the top surfaces of the bearing bars, cross bars or both notched. SPAN OF GRATING - The distancebetween points of grating support or thedirection of the dimension. Also referred to as length. STRAIGHT CUT - That portion of the cut edge or cutout of a grating, which follows a straight line. SWAGING - A method of altering the cross-sectional shape of a metal bar by pressure applied through dies. TOEPLATE - A at bar attached against the outer edge of a grating or rear edge of a tread, and projecting above the top surface of grating or tread to form a lip or curb. TREAD - A panel of grating having carriers and nosing attached by welding, and designed specically to serve as a stair tread. WELDED GRATING - Grating in which the bearing bars and cross bars are joined at their intersections by a weld. WIDTH - The overall dimension of a grating panel, measured perpendicular to the bearing bars and in the same direction as the cross bars.This catalog uses a form of the NAAMM alpha-numeric designation for bar spacing and manufacturing identication. The rst number signies center-to-center bearing bar spacing in 1/16ths of an inch*. A letter designates method of manufacture. The last number details center-to-center cross bar spacing in whole inches (usually 4" or 2")or rivet spacing (usually 3-1/2", 5" or 7").Methods of manufacturing and their letter designations used in this catalog include: SG ........ Swaged Rectangular Bar SGF ...... Swaged Flush Top SGI ....... Swaged I-Bar W .......... Welded Steel R .......... Riveted (Steel) AR ........

BAR GRATING18www.directmetals.com800.711.4939ALUMINUM RIVETEDA type of aluminum grating, which combines straight bearing bars and bent connectingbars riveted together at their contact points. Riveted grating, although being the oldest style of industrial footwalk, is still the choice of many engineers due to its reliability and durability. All popular sizes and spacings of riveted grating are available. ALUMINUM PLANKA type ofextruded grating, available In 6" wide sections and either plain sided or Interlock-ing. Plank can be provided in sections up to 26'0" in length or fabricated per plans and specs. Plank grating is available un-punched as an economical and structurally superior substitute for aluminum checker-plate or with a variety of punch/patterns. Aluminum ProductsALUMINUM FLUSH TOP A type of pressure locked grating in which the cross bars are in the same plane rela-tive 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 desired, a serrated surface can be provided. ALUMINUM RECTANGULAR BARA type ofpressure lockedgrating madebypermanentlyattaching cross bars to bearing bars through a pressure applied swagingprocess. Bearing bar sizes range from1" 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" are available. Where skid resistance is desired, aserrated 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 advantage of the aluminum extru-sion process by placing the metal where it is most effective, at the outermost ber, while reducing the thickness of the neutral axis web. This design consideration allows the same load carrying capacity at less weight per square foot than rectangular bar, therefore resulting in cost savings.PRESSURE LOCKINGThe most common method of manufactur-ing aluminum bar grating is through a process known as pressure locking.Pressure locked grating as de-ned by the NAAMM Metal Bar Grat-ing Manual is “Grating in which the cross bars aremechanically locked to the bearing bars at their intersections by deforming or swaging the metal.” Direct Metals® provides a permanently attached pressure locked joint, which will give long lasting life under normal service conditions.Aluminum Plank GratingGRATING TYPES AVAILABLE IN ALUMINUMWhere economy is a major consideration, the I-Bar SGI Series offers a popular andreasonably priced alternative to rect-angular bar grating. Extruded I-Bar sections have the same load carrying capacity with less weight per square foot than rectangular bars. The stri-ated top and bottom anges provide a “built-in” skid resistance feature without the added cost of serrating.

21800.711.4939www.directmetals.comAluminum Plank Section AvailabilityAluminum 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 provided unpunched or with a variety of punch/patterns for the passage of air, light, heat, or moisture. The interconnecting webs offer a ush top walking surface. Aluminum plank grating has found use in sewage and waste water treatment plants, as well as in the marine refrigerator (reefer), freezers and cargo-hold ooring market. Aluminum plank grating is available in ve cross-sectional 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 used primarily in water, waste treatment and the marine markets, while the Light Series and Reefer sections are exclusively in the marine refrigerator applications.Interlocking Heavy Duty, Reefer sections and edge sections are available in 1" deep grating only.Plank Punch / Pattern AvailabilityAluminum plank grating is available unpunched or with a variety of punch/patterns as shown below. Rectangular or square punched holes are most commonly used for water and waste treatment plants and in marine applications, while the round holes nd applications primarily in the marine market. The surface of plank grating can be specied 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.

33800.711.4939www.directmetals.comFIBERGLASSFiberglass Grating ProductsMOLDED FIBERGLASS GRATINGMolded berglass grating is a berglass-reinforced plastic (FRP) that combines berglass 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 ooring products. This product is best suited for corrosive environments.PULTRUDED FIBERGLASS GRATINGPultruded berglass 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 berglass has a grit surface for safety and a greater strength-to-weight ratio than molded berglass grating. A 35%/65% resin to glass ratio provides greater strength and less corrosion resistance than molded berglass. This product is best suited for longer spans.FIBERGLASS COVERED GRATINGOur berglass covered grating is a long-lasting, molded berglass oor product that combines smooth, gritted or checker plate and molded grating with any of our resin systems. It is the ideal choice when a 100% covered ooring surface is needed. Our berglass covered grating is often used in loading and storage areas with high foot and cart trafc 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 berglass 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 berglass panels offer ballistic resistant security with the additional performance advantages of durability, corrosion resistance, electrical non-conductivity, low thermalconductivity, and light weight.HEAVY DUTY FIBERGLASS GRATINGOur heavy duty berglass grating is available in both molded and pultruded grating systems. Both are designed to carry forklift and tractor-trailer loads that traditional molded and pultruded FRPgrating products are not designed to support. Heavy duty berglass grating provides greater durability for higher volume trafc areas as well. Additionally, heavy duty berglass grating can be used to free span longer distances than traditional berglass grating.CUSTOM MATCHED COLORS AVAILABLEWill match to any RAL color.FIBERGLASS STAIR TREADS & STAIR TREADCOVERSLightweight and easy to install, berglass stair treads are available in both molded and pultruded types to match the berglass oorgrating platforms. Fiberglass stair tread covers are made from a molded glass and resin system that is corrosion and impact resistant, re 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 berglass components and molded thermoplastic connectors. Our modular berglass grating handrail systems are available in 2" square or2" round congurations that are easy to grip, making them ideal for any high trafc area. Our berglass 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 berglass grating attachments and clips are specially designed to secure berglass grating or plates to the supporting structures.Additionally, they are used to fasten together adjacent gratingpanels, which minimizes load-induced differential deection. Allberglass 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, berglass 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 berglass structural shapes and pultruded berglass proles are made from a combination of berglass 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.

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.

The illustration shows that the strands and bonds create a distinct sharp angle to the original plane of the solid sheet.Flattened Expanded Metal is regularexpanded metal, which has been cold rolled, leaving a at and smooth surface.SIDE SHEARINGThe process of cutting a piece ofexpanded metal parallel to the longdimension of the diamond. Random Side Shearing - Side shearing is a cut made parallel to the LWD dimension of the sheet, which usually leaves open diamonds. Flat expanded metal SWD shearing tolerance is plus or minus 1/8" when both sides are sheared. Bond Side Shearing - This cut is made along the length of the sheet on the center line of the bond over the specied width. In most cases, it is not practical to attempt to Bond Side Shear either regular or attened expanded metalbecause of camber. END SHEARINGThe process of cutting a piece of expanded metal parallel to the short way of the diamond. End Random Shearing - The process of shearing a piece of expanded metal to a specied length (LWD). This cut normally leaves open diamonds at both ends, but accomplishes close tolerance (plus or minus 1/8") when both ends of atexpanded metal are sheared. End Bond Shearing - The process of shearing a piece of expanded metal to a specied length (LWD). A plus or minus 1/8" tolerance applies when both ends of at expanded metal are sheared. One end is cut on the Bond parallel to the SWD, the other end usually has open diamonds.NOTE: When end bond shearing isrequested for both ends of at expanded metal, the sheet is sheared at the center line of the bond over the specied length. A tolerance minus 0 plus 1/2" diamondapplies. It is possible to end bond shear, but extraordinary care must be exercised to maintain the squareness of the sheet. SQUARENESSWhen all four sides of a sheet of expanded metal are sheared, the maximum tolerance will be plus or minus 1/16" per foot of width.1/4" #20 Regular 1/4" #20 Flattened1/2" #16 Regular 1/2" #16 Flattened3/4" #13 Regular 3/4" #13 Flattened1-1/2" #9 Regular1-1/2" #9 FlattenedPatterns Shown Actual SizeSIDE BOND SHEARINGSIDE BOND SHEARINGSIDE RANDOM SHEARINGSIDE RANDOM SHEARING

45800.711.4939www.directmetals.comTerminologyCALENDERING - A rolling operation which attens the knuckles of wire cloth, giving it a smoother surface.CRIMP - Undulations in warp and ll wires, which hold each other in place.FILL WIRE - AKA shute wire, wirerunning across the width of the cloth.FILTER CLOTH - Cloth used for attening or straining (primarily plain and twilled dutch wire cloth and certain specications of square mesh and off-count standard wire cloth).HARDWARE CLOTH - Plain weave square mesh cloth of relatively light wire galvanized after weaving (usually between 2 to 8 openings per lineal inch).MARKET GRADE - Applies to wire cloth specications, most commonly used for general work. Market grade cloth is made of one size wire for each size closed mesh.MESH - Number of openings per lineal inch, measured from center of wire tocenter of wire.MICRON - 1/1000 millimeter, 0.00003937 inch. The unit of measure for particle retention of lter media.OIL TEMPERED WIRE - High carbon steel wire that is heat resistant to produce good strength and abrasion resistance.OPENING - Dimension between parallel adjacent wires. RECTANGULAR MESH - Wire cloth with different warp and ll wire mesh counts, which results in rectangular openings. The most common have a higher warp mesh than lter mesh. Advantages are increased open area, and reduced cost. SELVAGE - The nished edges of wire cloth running the length of the roll, which are produced by the weaving operation.SPACE CLOTH - Wire cloth specied by the opening size, rather than by the mesh count.SQUARE MESH - Mesh with equal spacing of warp and shute to give squareopenings.WARP WIRE - Foundation wires running parallel to the length of the cloth.WEAVES - Pattern in which wires areinterwoven.WIRE DIAMETER OR GAUGE - Diameter of wire used in weaving cloth.2 MESH WIRE CLOTH(count from center to center of wires)1/2 INCH OPENING WIRE CLOTH(clear space between wires)PLAIN WEAVEWires are crimped in a zig-zag fashion, with wires intersecting at every available crimp or pocket.INTERCRIMPWires are crimped in a zig-zag fashion, with intersections at every 3rd, 5th or 7th, etc., crimp or pocket.LOCK CRIMPDistinct crimp or pocket at wireintersection, with straight connectingsections of wire.FLAT TOPTop surface of wires all lie in same plane.Irregular crimped surface on underside.
