For gratings having cross bars at " centers add suffix - to item number. Increase tabulated weight to 1.1# for the 1/4" HW bearing bar sizes and # for the 3/8" HW bearing bar sizes. Supplementary cross bars can be installed in pairs on the underside of gratings with depths of 3" or more, when specified. These additional bars provide extra load distribution and lateral stability to the carrying members. For short spans, one set located at mid-point. For greater spans, two or three pairs depending upon spacing of supports. Where gratings are subjected to extremely heavy loading conditions, or rolling loads at 90 degrees to bearing bars, further assurance of satisfactory performance can be obtained by trim banding the ends of panels. Such band bars are usually 1/4" thick and 1/" less than the depth of the grating and welded flush with the top of the grating. anding must be specified. Heavy Weld Series GH (19W4) Series GH- (19W) NOTE: GH and GH- is produced via the electroforge process. This grating is not normally used for standard floor layouts, but is usually selected by engineers for rolling or vehicular loads for narrow space work. Theoretical values based on F = 0,000 psi.

Aluminum oxide grit is bonded to a metal base using a metal bonding agent. Surface can be specified on either a steel on steel, aluminum on aluminum, aluminum on steel, or aluminum on galvanized steel base. Steel based products are finished with a standard shop coat of paint applied to the underside surface. A galvanized finish can be applied over the entire surface when a steel bonding agent is specified. GRIP TIGHT products come in 4 grades of slip resistant coatings. McNIHOLS offers the most aggressive. All grades/profiles of GRIP TIGHT products exceed the minimum.60.o.f. required by many municipalities.

Fig.1 deflection () Fig. Fig.3 deflection () Load Table Explanation LOA LOA LOA s deflection ( s ) The following information refers to Regular GRIP STRT Safety Grating hereinafter referred to as grating. HOW TO REA LOA TALES To select size of grating, determine load, clear span and deflection requirements. Having this information, select from the appropriate load tables to find the appropriate plank to meet job requirements. FOR EXAMPLE: If you require a clear span of 4'0", concentrated load of 300# at.05" maximum deflection and have chosen regular GRIP STRT, you would verify the following: 8-iamond GRIP STRT 18-3/4" wide, -1/" height, 1 gauge steel will carry a load of 416# at a 0.18" deflection. This is one size to do the job. Other sizes will carry more load if necessary. For more economical selection, choose the greatest width that will support the load consistent with the job requirements and choose deeper channels rather than heavier steel gauges. Grating will generally carry similar concentrated loads, tabulated in pounds at mid-span, for a given span, material gauge and height, regardless of width. The uniform load tables are tabulated in lb./sq. ft., which accounts for the difference in load capacity shown for various widths. eflection is in inches. To ensure the safety of the tabulated loads, two aspects of grating strength must be considered. The first consideration is transverse bending in the grating surface, which is referred to as strut flexure. This occurs when the grating is loaded with either a uniform load or a mid-width concentrated load, and the struts (grating surface) deflect relative to the side channels. To determine the allowable strut loads, samples of each plank material and thickness were tested for each plank width. (see Fig. 3). The data resulting from these tests was used to prepare strut loading tables for regular GRIP STRT which give allowable loads and deflections considering strut flexure only. These allowable strut and rung loads have been incorporated in the Product Selection esign Tables. The second aspect of the grating strength is channel flexure. This occurs when the channels at midspan of the grating deflect relative to support points. To verify the performance of the side channels, samples were loaded with concentrated and uniform loads at different spans. To approximate the most severe condition, there were no attachments between the channels and the supports. In cases where spans are shorter, channels deeper and grating wider, strut flexure becomes more critical. With the exception of 8- and 10- iamond regular GRIP STRT, it can be assumed that both side channels effectively support the concentrated load, and the grating surface deflection is negligible. ased upon these assumptions, the following values found in the load table have been determined: If grating surface deflection should be considered when selecting a product to meet a particular specification, then the deflection of the mid-width of the grating, relative to the side channels, can be calculated using both the data in the Strut Loading Tables and the Load/eflection onversion formula. All load tables show maximum loads, based upon actual load tests. NIFORM LOA () application to all grating: Maximum load(lb/ft ) permitted by flexural stress in side rail or grating strut, whichever is lower, applied to entire grating area (fullwidth by clear-span) between supports. ONENTRATE LOA () application to all walkways/planks: Maximum load(lb) permitted by flexural stress in side rail or grating strut, whichever is lower, applied transversely to total width of grating at mid-span and assumed to be carried equally by both side rails.
