Hollow Core Floor Slabs, Precast Prestressed Hollow Core Slabs for Flooring

New Extrusion System to address
North American performance challenges
for hollow core slab producers

Since 2008, hollow core slab prices have experienced a pointed drop. In some regions, prices have dropped by 30-40% making the task of turning a profit very challenging. This has posed a tough problem. A problem that has not and, most likely, will not return to pre-recession levels for some time to come.

Thus the need now in the industry is for producers to have efficient, dedicated and primary production lines for hollow core. The lack of same is driving secondary or hybrid hollow core producers to re-examine their business strategy due to unsustainable price pressures and rising maintenance costs associated to fatigued equipment. In response to the new challenges, a multinational concrete manufacturer recently created a new corporate position of VP, Concrete Performance, with a mandate to make all operations efficient or abandon the sub-segment it serves.

The performance of hollow core plants across North America now have the daunting assignment to reduce costs in proportion to the drop in market pricing. Accep - table performance standards must be reduced by the same factor to achieve the profitable operations many producers are now in need of. Those not addressing are finding it too costly to go on. The inevitable solution is a complete audit of the hollow core performance and cost structure.

Tower of America, Milestone Hollow Core structure, Ultraspan ''Extruding Excellence from last 50 years''

Palanisami & Associates of Minneapolis, Minn., was fortunate to be a part of the design and construction of an apartment tower in 1995 that was sure to be an engineering milestone. The New York, N.Y.–based LeFrak Organization, the building’s developer, was in the middle of a $10 billion mixed-use, multibuilding development on the Hudson River waterfront in Jersey City, N.J., called Newport, when it chose to undertake a new kind of building. Tower of America West (TOA), as this building is known, would have 346 rental units and an attached parking structure and would be set among many similar apartment towers proposed as part of the development. However, the uniqueness of this tower would be more than skin deep.
