We also made use of the existing steel columns of the building in order to fix the supporting channel beams to it with square tube columns in between to half the span of the bearer thereby reducing the size of it making for easier installation and cost effectiveness. On the opposite wall we fixed the channel directly to a concrete beam thereby eliminating the use of more columns. The new 200sqm structural mezzanine floor linked up nicely with the old mezzanine with a difference of one step.
We worked out the load per square meter according to the type of stock that will be packed onto the steel shelving units on top. Taking the passage ways into account we worked on a load of 350kg's/sqm which allows for the shelving units to be loaded to a maximum of 600kg's per double, back to back unit which is more than sufficient for their current requirements.
