Kovalska ICG produces a wide range of floor slabs by applying the extrusion method on the up-to-date technological line for the off-form slab formation manufactured by Nordimpianti System S.r.l. (Italy). These are multi-cavity prestressed slabs made of heavy concrete by applying the method of continuous long-line extrusion process*. Hollow core floor slabs may be used to arrange load-bearing structural floor and roofing elements of buildings and structures for various purposes. Slabs manufactured by applying the extrusion method are used in construction of residential and industrial facilities with load-bearing walls made of bricks or blocks, as well as in frame or frame and monolithic structures to cover spans of up to 20 m inclusive. They are an alternative to slabs manufactured by applying conveyor-type production method or conveyor technologies. Slabs are made with a height of 200, 220, 265, 320, 400 and 500 mm, and a width of 550, 750, 950, 1100, 1350 and 1500 mm with a height of 220 mm. Slabs with a height of 200, 265, 320, 400 and 500 mm can be made with a width of 1200 mm, or shortened in width according to an individual order.
*Extrusion (pushing out) is the technology of manufacturing reinforced concrete products by forcing concrete mortar through forming holes. In lifting and carrying out erection operations without lifting hooks, special traverses with clip-on chucks are used.
