Bethlehem builds 8 inch, 10 inch, 12 inch, 12.5 inch and 16 inch Hollowcore plank. Hollowcore plank is a cost-effective structural system for floors, roofs and other applications. The voids in the plank offer weight savings while the prestressed strand increases load capability and span. Concrete’s fire-resistant nature as well as the ability to reduce sound transfer between rooms can also be very helpful to a project.
Hollowcore plank contain prestressing strand designed to meet the loading requirements of your structure. These planks can be used in longer spans than traditional flooring systems due the decreased weight. This proves advantageous for the longevity of support columns.
Like all of our precast products, these planks are naturally fire resistant and diminish the possibility of progressive collapse.
