Can I install the mezzanine in my apartment? Will the structural floor bear the weight?
Yes. As they are manufactured with light steel profiles with a high yield point they are very light and the load per column is very low. The only restriction is the storage load on the mezzanine: instead of 40.96lb/ft², it may be reduced to 1764lb for the whole mezzanine.
A home with a concrete structure usually supports a point load of at least 441lb on a surface of 2x2". The T8 mezzanine weighs 439lb and the T15 mezzanine weighs 785lb, both weights are distributed over 4 columns.
You can install either of these two metal mezzanines in your home, provided that the load stored on them is limited. Ask MezzaninesOnline about the specific features of your project.
