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.

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.
