SAFETY GRATING GRIP STRUT Every year industrial accidents such as falls tripping over debris slipping on wet or greasy surfaces cost millions of dollars in lost man hours and production By reducing accidents insurance costs can frequently be decreased Grip Strut Safety Grating helps reduce accident rates by providing a safer walking working surface than any other available grating product It s serrated surface gives maximum slip protection and performance under practically all conditions and in every direction The serrated surface is designed in an open diamond pattern This allows drainage of fluids mud chips and other accident causing debris With 4 1 2 high side channels Grip Strut Safety Grating Walkways meet OSHA requirements for toeboards on elevated structures SAFER SERRATED SURFACE The 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 INSTALLATION Light 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 devices permit fastening to most existing surfaces allowing for fast installation or disassembly SERRATED GRIP STRUT GRATING Offers excellent slip resistance wherever maximum safety underfoot is essential Material meets anti slip values set forth in Federal Specification RR G 1602A NON SERRATED GRIP STRUT GRATING For all purpose use where a high degree of slip resistance is required with a smoother texture and design Product availability is subject to extended lead time STANDARD GRIP STRUT GRATING PLANKS Available 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 www directmetals com 800 711 4939 1

SAFETY GRATING TRACTION TREAD FLOORING Traction Tread Flooring features a surface with hundreds of perforated buttons that provide slip resistance in all directions making it a practical choice for industrial applications Traction Tread is also appropriate for commercial applications where pedestrian traffic is a consideration perfectly suited for ADA compliant requirements Traction Tread is easily adapted for a multitude of applications offering a safe walking working surface for walkways ramps stair treads and equipment platforms Traction Tread is ideal for the manufacturers of special and fabricated products and is often used as a reconditioning material over existing surfaces that do not provide slip resistance Traction Tread flooring is readily available in stock sheets designed for secondary fabrication requirements Material Options Hot rolled pickled and oiled carbon steel 11 gauge 5 0 lbs sq ft 13 gauge 3 8 lbs sq ft 16 gauge 2 5 lbs sq ft Standard Pattern V Pattern Aluminum alloy 5052 H32 125 1 6 lbs sq ft Note 14 ga 12 ga carbon steel and 16 ga 304 stainless steel are also available Sheet Size Standard 36 x 120 Cut to order Traction Tread is available as shown above as a standard product however variations to the surface design can be produced according to your requirement see examples illustrated below 14 Star Pattern Square Pattern Rectangular Pattern OEM Pattern Drain Hole Pattern Non Perforated Pattern www directmetals com 800 711 4939

BAR GRATING ALUMINUM PRODUCTS ALUMINUM FLUSH TOP A type of pressure 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 desired a serrated surface can be provided ALUMINUM RECTANGULAR BAR A type of pressure locked grating made by permanently attaching cross bars to bearing bars through a pressure applied swaging process 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 with cross bar spacing of 4 or 2 are available Where skid resistance is desired a serrated surface can be provided ALUMINUM RIVETED A 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 engineers due to its reliability and durability All popular sizes and spacings of riveted grating are available ALUMINUM PLANK A type of extruded grating 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 unpunched as an economical and structurally superior substitute for aluminum checkerplate or with a variety of punch patterns ALUMINUM I BAR A type of pressure locked grating which utilizes an I shaped bearing bar ranging in size from 1 x 1 4 through 2 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 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 design consideration allows the same load carrying capacity at less weight per square foot than rectangular bar therefore resulting in a cost savings 28 Aluminum Swaged Grating PRESSURE LOCKING The most common method of manufacturing aluminum bar grating is through a process known as pressure locking Pressure locked grating as defined by the NAAMM Metal Bar Grating Manual is Grating in which the cross bars are mechanically 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 FLUSH TOP GRATING Aluminum Flush Top grating combines the sure lock reliability of swage locked grating with the cosmetic appeal and added walking surface of traditional pressure locked grating Best of all by taking advantage 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 a requirement Field cutting is also possible ALUMINUM RECTANGULAR OR I BAR GRATING These 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 Bar sections this manufacturing process offers the economy of cutting individual pieces from panels enables field alteration of grating panels and allows banding as an option rather than as a requirement Aluminum Plank Grating www directmetals com 800 711 4939
