The Speedfloor suspended concrete floor system uses a cold formed steel joist as an integral part of a concrete and steel composite floor The joist is manufactured from pregalvanised high strength steel in a one pass rollformer giving a high degree of accuracy at a fast production rate The ends are simply bolted to the joists which are then ready for transport to site At site, the flat slab with drop panel and column head Flat Plate A flat plate is a one or twoway system usually supported directly on columns or loadbearing walls Figure It is one of the most common forms of construction of floors in buildings The principal feature of the flat plate floor is a uniform or nearuniform thickness with a flat soffit which requires only simple formwork and isSuspended slabs are made of concrete and steel mesh, the same as a ground slab They are normally prefabricated offsite, and transported by truck Some slabs have hollow channels running through them these 'hollow core slabs' are used to help reduce weight, and also to allow cabling and piping to be run through the slab
