Hollow core slabs are pre-stressed concrete elements that have a constant cross section. They are manufactured using high tensile strength pre-stressed strands or single wire which is embedded within the element. The production of these elements is achieved using our Extruder and Slip-former machines that cast in one phase along a production bed without the need of any formworks. Hollow core slabs are highly developed structural elements and are used all over the world due to their many advantages and diverse applications. Today they are one of the most well-known prefabricated elements because of their technical and economic characteristics. Hollow core slabs are widely used for flooring and wall panels in industrial, commercial, residential and infrastructure construction. Hollow core slabs can be used with different supporting structures: concrete constructed walls, brick built walls, steel structures, on-site concrete cast structures, prefabricated beams etc. For infrastructure hollow core slabs are used extensively to protect roads from natural dangers. They are used to construct anti-landslide and avalanche guards as well as the road decking itself, all elements requiring high loading specifications. Moreover hollow core slabs possess certifiable fire resistances and offer an economic solution to construct fire stop walls for warehouses, industrial buildings and car parks.
