These mezzanines will be covered with Mezher Metal deck sheets OLG-100. These sheets are suitable under high loads and stresses and have special pockets for better adhesion with concrete. Affordable and with a low pitch profile, they are available in 0.5 mm or 0.6 mm thick steel galvanized at 275g/m². Edge trimS can be provided along the perimeter of each mezzanine and act as permanent concrete edge stopper.
