The company I work for has a smallish mezzanine floor installed in the warehouse. However, much debate is arising about the maximum loading it can take. The installer told us 500 kg/ sq m. We have an unevenly distributed load on the floor and some of our stock weighs 450 kg and rests on 4 small feet. I guess I am just asking for some advice from those who have experience of this kind of thing.Is it safe to place heavy units on feet up on the mez?
