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.
