Heavy Duty Grip Strut Grating - AdvantagesHeavy Duty Grip Strut overviewEvery year, falls cost industry millions of dollars in lost time andproduction. The safer walking-working surfaces of Heavy DutyGrip Strut safety grating products help reduce accidents, andin doing so, may help cut insurance costs.The secret is in the serrated surface and open design. Theopen diamond pattern allows fluids, mud, chips, ice andsnow to fall through. The serrated surface helps provide highfriction for maximum slip protection in all directions, and underpractically all conditions. The resilience of Grip Strut gratingcushions the impact of walking, lessening worker fatigue andincreasing efficiency.Application versatility Variety of standard plank widths and channel heights canbe combined with numerous special-order items to meetalmost any application requirement. Special sizes and fabricating services are available forunusual requirements. May be painted, hot-dip galvanized after fabrication,anodized, plated, plastic-coated or specially finished inother ways to fit service requirements. F inish coatings are economically applied since all surfacesare accessible to brush or spray.Heavy Duty Grip Strut safety grating products offer theadvantage of regular Grip Strut safety grating, but are designedfor applications of greater load and/or longer span. Basic designis the same, but diamond openings are larger and metal isthicker. Heavy Duty grating products are available in many of thesame configurations, materials and finishes as regular Grip Strutsafety grating. Heavy Duty Grip Strut grating products include:planks, walkways and stair treads; for specification see pages84 & 85. For specifications and information on regular Grip Strutsafety gratings, see pages 28-29.High load capacity, long lifeCompliance with regulatory codes / standards E xceeds Federal Specification RR-G-1602D requirements. Meets OSHA toeboard requirements for elevatedstructures with standard upturned, 5 inch high integral sidechannels.Low life-cycle cost L ower upfront material costs and long-lasting, corrosionresisting finishes help provide long service life to all GripStrut gratings: steel or aluminum. Brawny yet lightweight, these planks, walkways and stairtreads permit substantial reduction in supporting structuralmaterials. High strength-to-weight performance is achieved throughsection depth and integral side-channel design. Bridged struts form a rigid, strong plank surface thatcarries large loads with minimum deflection. Self-cleaning open design is virtually maintenance-free.Fast, simple Installation No rivets, fabricated joints or pressure joints to loosen orbreak. L ight and simply installed. Regular maintenance personnel can do the job.Safety at all levels Serrated surfaces grip soles securely in all directions. Sections are easily field-cut, at virtually any angle, andfield-adapted; connections are rapidly made with bolts,clamps or welding. Non-slip sheared edges are ideal for both indoor andoutdoor locations — wherever mud, ice, snow, oil anddetergents can create hazardous walking conditions.Heavy DutyGrip Strut Grating Disassembly, when needed, can be just as rapid.Minimal maintenance Openings allow fluids, chips, stones and mud to quicklydrop through. Ice easily shears off under normal footpressure. Open design is easily cleaned with a brush, liquid or airspray.Tested performance – slip resistance vs. federal specificationA BA BA BA BA unds of ForceStatistics show falls as the second highest cause of lost-time injuries in industry. Yet tests prove that falls can be reduced bythe safe surface of Heavy Duty Grip Strut safety grating, planks, walkways and stair treads. And fewer accidents mean lowerworkmen’s compensation insurance costs, to save the cost of Grip Strut safety grating many times over. Independent laboratorytests prove that Heavy Duty Grip Strut safety grating exceeds Federal Specification RR-G-1602D requirements for slip resistance.Five shoe soles were tested, in longitudinal, transverse and diagonal directions; under five conditions: dry, greasy, muddy, soapyand icy. Heavy Duty Grip Strut safety grating tested more slip-resistant than other gratings (depending upon the condition).AFederalSpecificationfor SteelB10 Gauge SteelHeavy-DutyGrip StrutGrating(1) V alue of force required to move 1 175 lb. load a distance of one inch acrossthe grating surface of two Heavy-Duty Grip Strut serrated style safety gratings (B & C) compared with the respective Federal Specification RR-G-1602Dstandard (A).

Heavy Duty Grip Strut Grating - General Load InformationWalkways, Planks and Stair TreadsGeneral load informationSiderail strength usually controls, but with shorter spans, deepersiderails, and/or wider grating surfaces, flexural strength ofindividual struts may control. In sizing walkways or planks withstrength as a design criterion, be sure to check Heavy Duty GripStrut safety grating for both: (1) strength of walkways/planksiderails, (2) strength of individual struts in grating surface. Withdeflection as a design criterion, loads may be limited by either:strength of individual surface struts, or total deflection of onesiderail at midspan plus a surface strut at midwidth of walkwayor plank (sum of siderail deflection plus strut deflection).Flexural load tables have been calculated according to designload limiting criteria, and if not illustrated in this catalog they canbe obtained from our technical services.All load tables show maximum loads, based upon actual loadtests performed at the Pinckneyville (IL) plant, and determinedin accordance with AISI “Specification for the Design of ColdFormed Steel Structural Members" , 1980 Edition, using minimumyield strength of 33 ksi for steel, 23 ksi for aluminum. Loads aredesignated:Heavy Duty Grip Strut safety grating walkways and planks areavailable in three thicknesses of steel and one of aluminum;walkways have one standard siderail height, planks have four.In each category, walkways come in three widths, planks infive. Begin sizing, for maximum economy, with widest practicalgrating for the job (shallowest siderails and thinnest gauge); ifthis does not meet required load capacity, first consider deepersiderails, then heavier gauge, and finally narrower grating width,if necessary.“Strut Load Tables” show flexural strength and deflection ofindividual grating surface struts relative to siderails. Sincethese are maximum values in the elastic range, lesser loads anddeflections can be proportioned from them.Design load assumptions differ according to load type:(1) uniform, (2) concentrated (see Figures 1, 2 and 3 below forexplanation of load application). Concentrated load capacitiesgenerally vary with span, siderail height and material thickness,irrespective of grating width, although large differences ingrating width cause concentrated loads to be distributedsomewhat differently into siderails.(U) for uniform, in./ft.2(C) for concentrated, in./lb.(D) for corresponding deflections, in inchesLoad - CLoad -ULoad - CsHeavy DutyGrip Strut GratingDDDFigure 1Figure 2Concentrated load (C)applications to all walkways/planks:Maximum load (lb.) permitted by flexuralstress in siderail or grating strut, whicheveris lower, applied transversely to total widthof grating at midspan and assumed to becarried equally by both siderails.Concentrated load (Cs)applications to grating surface struts ofall walkways/planks:Maximum load (lb./ft.) permitted byflexural stress in grating strut, appliedlongitudinally to a 1 foot length of gratingat midwidth.Deflection (D) in all walkways/planks:Deflection (in.) corresponding to maximumload (U) or (C) permitted by flexural stressin siderail or grating strut, whichever islower, applied as defined in Figures 1 or2, and 3.Deflection (D) in all walkways/planks:Deflection (in.) corresponding to maximumload (U) or (C) permitted by flexural stress insiderail or grating strut, whichever is lower,applied as defined in Figures 1 or 2, and 3.Deflection (Ds) in all walkways/planksDeflection (in.) corresponding to maximumconcentrated strut load (Cs) permittedby flexural stress in grating strut, appliedlongitudinally to a 1 foot length of gratingat midwidth.Uniform load (U)applications to all walkways/planks:Maximum load (lb./ft.2) permitted byflexural stress in siderail or grating strut,whichever is lower, applied to entiregrating area (full-width by clear-span)between supports.64Eaton’s B-Line series safety gratingswww.eaton.com/b-lineseriesFigure 3
