INCO 70.4 COLABORANTE Slab Depth (mm) LOAD TABLES Temporary supports in the middle of the span Fire Resistance: Due to the characteristics of the composite slabs, 30 minutes resistance fire (R30) is assured. In case of needing a higher resistance than this one, the following alternatives should be considered: -Protective material projected under the composite slab. -Installation of false ceilings -Additional reinforcing steel against fire, for further information about this consult with our Technical Department.
