AAC (aka Aircrete, Thermalite) wall + IKEA ALGOT shelf weight load capacity
Here you go - Multiply the number of brackets by the safe load of the bracket to determine the safe load capacity for the entire shelf. For a shelf that has three brackets rated for 250 lbs. the safe load for the brackets is 62.5 lbs., and the capacity for the shelf, as a whole, would be 187.5 lbs.  I was going to do the math but math.
