Steel Load Table Spans in the darker shading (to the left of the heavy line) have a deflection of less than 5mm for a 4kPa uniformly distributed load. Mass shown is untreated and unbanded. Galvanising and banding will increase the mass as follows; A/B Pattern 12% nominal C/D Pattern 14% nominal F Pattern 16% nominal Load deflection tables are arranged in rising strength order. See the 4kPa, 5mm deflection column. U = Superimposed uniformly distributed load in kPa (100kg/m2 = 0.98kPa) D = deflection in mm for the load U Assumptions for load capacity is on single spans Based on allowable stress...
