U Channel Grating: U shaped grating panels have much higher strength and ductility than cast iron grates. They are suitable to be used as well covers and gully covers applicable to environments of large span and heavy load such as docks and airports, etc.
For applications where extremely slippery conditions prevail, Serrated bar grating offers a superior grip surface to the load bearing bars. Bar grating types are specified by bearing bar spacing followed by cross rod spacing. In imperial measurements, bearing bar spacing is described in sixteenths of an inch.
LIGHT DUTY LOAD TABLE WELDED STEEL BAR GRATING Welded steel bar gra ing imanuf actured by re stance-weld process. Crossbars are fused to bearing bars to form a permanen tjoint. Economi cal, ye durable for most appli a-tions. Available in standard panel widths of 2’ or 3’ and lengths of 20’ or 24’.

1. Select type of grating • “W” for welded steel grating • “DT” for dovetail pressure locked grating • “SL” for swage locked grating 2. Select bar spacing from table above 3. Select bearing bar size (consult load tables considering service loads and clear spans) 4. Specify plain, serrated, or Algrip surface 5.
Deflection: Spans and loads to the right of the bold line exceed 1/4" deflection for uni-form load of 100 psf which provides safe pedestrian comfort. These can be exceeded for other types of loads with engineer’s approval. Serrated Bars: For serrated grating, the depth of grating required for a specified load is 1/4" deeper than that shown in
How to Specify Heavy Duty Bar Grating. Select type of grating “W” for Welded Steel Grating “WS” for Welded Stainless Steel Grating; Select bar spacing from table above; Select bearing bar size from Load Tables; Specify Plain or Serrated surface; Specify banding and any additional trim required; Specify finish Bare steel (no finish)

Load deflection tables are arranged in rising strength order. See the 4kPa, 5mm deflection column. U = Superimposed uniformly distributed load in kPa (100kg/m 2 = ) D = deflection in mm for the load U Assumptions for load capacity is on single spans. Based on allowable stress of 171 mPa for steel.
Reference to the following load tables will assist in choosing the most practical and economical type of grating to suit the required span and loading criteria. Values are uniformly distributed loads stated in kN/m2 and have been calculated with deflections limited to 1/200th of the span or 10mm whichever is the lesser.
