Photo shows serrated surface 5 diamond plank. For the safest walking-working surfaces! Every year industrial accidents falls, tripping over debris, slipping on wet or greasy surfaces cost millions of dollars in lost manhours and production. By reducing accidents, insurance costs can frequently be decreased. GRIP STRT Safety Grating helps reduce accident rates by providing a safer walking-working surface than any other available grating product. Its serrated surface gives maximum slip protection and performance under practically all conditions and in every direction. In addition to safety, the resilient surface of GRIP STRT cushions the impact of footfalls thereby lessening worker fatigue and increasing efficiency. GRIP STRT is your best safety buy. Safer, serrated surface These non-slip GRIP STRT 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. Maintenance-free open design Permits quick drainage of fluids, chips, grease and mud. Any ice accumulation shears easily under normal foot pressure. Open design allows convenient access for cleaning. High load capacity, long life Bridged struts with integral side channels form a plank that can support loads with minimum transverse and longitudinal deflection. There are no rivets or pressure joints to break or loosen. This sturdy construction provides the advantages of heavy load carrying capacity with minimal deflection, rugged durability with longer-lasting performance. With 4-1/ inch high side channels, GRIP STRT Walkways meet OSHA requirements for toeboards on elevated structures. Fast installation Light, 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 field cut at virtually any angle, or fabricated to adapt to field conditions. Economical to install, use Standard mill-galvanized finish resists corrosion. High-strength aluminum and Types 304 and 316L stainless steel are available to provide maximum corrosion resistance. Black unpainted steel is available for installations requiring hot dip galvanized finish after fabrication. 3 diamond shown GRIP STRT Ladder Rungs Reverse Diamond Rungs - Diamonds can also run the opposite direction by special order.

5 The following information refers to Regular or Heavy Duty GRIP STRT Safety Grating or GRATE-LOCK Grating hereinafter referred to as grating. Load Tables: GRIP STRT p. 51 Heavy Duty GRIP STRT p. 65 GRATE-LOCK p. 70 Load HOW TO READ LOAD TABLES: To select size of grating, determine load, clear span and deflection requirements. Having this information, select from the appropriate load tables for regular GRIP STRT, Heavy Duty GRIP STRT or GRATE-LOCK Grating to find the appropriate plank to meet job requirements. FOR EXAMPLE: If you require a clear span of 4'-0", concentrated load of 300 lbs. at 0.5" max. deflection and have chosen regular Grip Strut, you would verify the following: 8-Diamond GRIP STRT, 18-3/4" wide, -1/" height, 1-gauge steel will carry a load of 416 lbs. 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 job requirements and choose deeper channels rather that 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. Deflection 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 rela- tive 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 and Heavy Duty GRIP STRT and rung loading tables for GRATE-LOCK Grating, which give allowable loads and deflections considering strut flexure only. These allowable strut and rung loads have been incorporated in the Product Selection/ Design Tables for regular GRIP STRT and GRATE-LOCK Grating (not Heavy Duty GRIP STRT). 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-Diamond regular GRIP STRT, it can be assumed that both side channels and all widths of GRATE-LOCK and Heavy Duty GRIP STRT effectively support the concentrated load, and the grating surface deflection is negligible. Based upon these assumptions, the following values found in the load tables 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/Deflection Conversion formula. All load tables show maximum loads, based upon actual load tests. Loads are designated: () for uniform in lb./ft., (C) for concentrated in lbs., (D) for corresponding deflections in inches. D Fig. 1 NIFORM LOAD () application to all grating: Maximum load (lb./sf) permitted by flexural stress in side rail or grating strut, whichever is lower, applied to entire grating area (full-width by clear span) between supports. DEFLECTION (D) in all walkways/planks: Deflection (in) corresponding to maximum load () or (C) permitted by flexural stress in side rail or grating strut, whichever is lower, applied as defined in Figs. 1 or, and 3. D Load C Fig. CONCENTRATED LOAD (C) application to all walkways/planks: Maximum load (lb) permitted by flexural stress in siderail or grating strut, whichever is lower, applied transversely to total width of grating at mid-span and assumed to be carried equally by both siderails. DEFLECTION (D) in all walkways planks: Deflection (in) corresponding to maximum load () or (C) permitted by flexural stress in side rail or grating strut, whichever is lower, applied as defined in Figs. 1 or, and 3. Load C s Fig. 3 CONCENTRATED LOAD (C s ) application to grating surface struts of all walkways/planks: Maximum load (lb./ft.) permitted by flexural stress in grating strut, applied longitudinally to a 1 ft. length of grating at mid-width. STRT DEFLECTION (D s ) in all walkways/planks: Deflection (in) corresponding to maximum concentrated strut load (Cs), permitted by flexural stress in grating surface strut, applied longitudinally to a 1 ft. length of grating at mid-width.

Eight and 10-Diamond products are wide enough to require a change in the assumptions used to prepare the - and 5-Diamond Product Selection/Design Tables. No longer will it be assumed that both side channels are equally effective in supporting a concentrated load. In fact, to provide a high level of safety, it will be required to carry 100% of a concentrated load. Also strut deflection for 8 and 10-Diamond products may be significant. The most critical case occurs when a concentrated load is located at mid-span and mid-width. To determine how the struts perform under this loading, 3-ft. long samples of each material and thickness were tested. For these tests the side channels were continuously supported and loads were applied using 1' long and 1" wide bar placed parallel to the side channels mid-width and the longitudinal center. Results of these tests, proved the performance of these materials when a concentrated load is applied mid-span and midwidth. If a concentrated load is to be applied at mid-width at the end of a plank, consult the strut loading table. The following values have been tabulated for 8 and 10- Diamond grating. Allowable niform Load () (For charts at left) Values are given in the rows labeled and are the lowest of the (1) maximum allowable uniform loads considering channel flexure, and () maximum grating surface flexure. Deflection Corresponding to (For charts at left) Deflection values appear in the rows labeled D, below the values, and are maximum deflections the allowable uniform loads would produce. Maximum deflections will occur at mid-span and mid-width and will be the sum of side channel and grating surface deflections. (Fig.3) Allowable Concentrated Load (C) (For charts at left) Values tabulated in the rows labeled C are the lowest of the (1) maximum allowable concentrated load considering side channel flexure (with one side channel supporting the entire load Fig. ) and () the maximum allowable strut flexure. (Fig.1) Deflection Corresponding to C (For charts at left) Deflection values are indicated below the C values in the table and are deflections the allowable concentrated loads will produce at mid-span and at mid-width. The deflection is the sum of side channel and grating surface deflections.

Basic design is the same as regular GRIP STRT, but diamond openings are larger and metal is thicker. Heavy Duty Grating is available in many of the same configurations, materials and finishes. A variety of standard plank widths and channel heights can be combined to meet any application requirement. High strength-to-weight performance is achieved through section depth and integral side channel design. Bridged struts form a rigid, strong plank surface that carries large loads with minimum deflection. Material cost is low, erection cost nominal. Long lasting, corrosion-resisting finishes provide long service life to all GRIP STRT Gratings: steel or aluminum. These brawny planks, walkways and stair treads permit substantial reduction in supporting structural materials. Planks are light, simply installed by 1 or persons. Sections are easily field cut, adapted; connections are rapidly made with bolts, clamps or welding. Disassembly can be just as rapid.
