  • For the design of heavy-duty bar grating, load bearing capabilities and deflections are based on the structural properties of the bearing bars and the number of bearing bars supporting the load. Grating is designed so that the allowable stresses of the metals used are not exceeded when design loads are applied, or if deflection governs, specified C – Safe Concentrated Load in lbs. per foot of grating width. D – Deflection in mm. Loads and deflections given in this table are theoretical and are based on a maximum allowable fibre stress of 124.0 Mpa. NOTE: Spans and loads to the right of the heavy line exceed a deflection of 1/4″ for uniform loads of 100 pounds per square foot. Mass shown are untreated and unbanded. Load deflection tables are arranged in rising strength order. See the 4kPa, 5mm deflection column. Based on allowable stress of 171 mPa for steel. Recommended minimum landing is equal to grating depth greater than or equal to 25mm.

McNICHOLS also has a complete line of Bar Grating Stair Treads and available resources. For information on Bar Grating Stair Treads, please visit our Stair Tread Resources landing page. Following selection of the type of grating, consult the load tables to select the appropriate bearing bar size for the loads and spans to be served. To complete the specification, indicate which of the three materials is desired for the application, carbon steel, aluminum or stainless steel. Bar Grating load tables enable the user to select the appropriate bearing bar size for the actual uniform and/or concentrated load carrying capacity and a corresponding deflection for each size/type of bar grating at a given unsupported span. Additional details regarding Load Table Terminology & Formulas available. 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 = 0.98kPa) D = deflection in mm for the load U. Assumptions for load capacity is on single spans.
