The racks to be 4.0m high at 1.0m centers with bracing in every other bay. The rack shelves to be 1.0m long cantilever beams supporting 300kg load.

Base beam is allowed to transfer the loads to the industrial slab and to counter the overturning.

Load on rack arms 300kg = 3kN

Allow for dynamic factor 1.5 = 1.5 x 4.5 kN
