FP McCann manufactures precast concrete hollowcore flooring units. These units are a prestressed concrete slab normally 1200mm wide (part widths are also available if required) and a current depth range of 150mm to 450mm. In addition to this range, we also manufacture a 100mm deep precast concrete floor slab.
Our hollowcore slab production techniques are constantly being updated and developed to offer additional slab depths to the range and also increase efficiency and achieve higher quality. As with our other flooring products, hollowcore slabs can be used with masonry, steel precast and in-situ forms of construction.
Whether you require a small 60m2 plot or a 10,000m2 floor, we have the slabs and the capacity to suit your needs. We work with everyone from multinational construction companies, architects and engineers to self-employed builders and we will always aim to work efficiently and effectively to build solid working relationships
NOTE: Tables are given as a guide only. When using maximum spans, consideration to the effect of camber/ deflection on finishes/ internal partitions is advised. Reinforcement patterns will vary, dependent on the spans/ loads specified.
Tables do not consider reduced capacities for potential service hole requirements or additional loads to those stated above. For alternative load/ span combinations, including service hole requirements or composite designs, please consult the FP McCann design office.
* 2hrs are available. Please consult the FP McCann design office for further details.
