When constructing multifamily or mixed-use buildings, architects and engineers are challenged with finding a solution that allows for quick erection, increased safety, and enhanced design versatility. County Prestress’ Hollowcore Roof and Floor Systems are a high-performance solution that meets project specifications and shortens construction schedules.
Structural Integrity
Hollowcore plank is a resilient building material that supports high load capacities across long, open spans, eliminating the need for extra load bearing columns. Its prestressed fabrication helps the planks achieve high-performance strength with the use of less concrete. This design allows for unobstructed ceilings that maximize the usable space.
Increased Safety
When building multi-unit facilities, safety becomes an increasing concern. County Prestress’ Hollowcore Roof and Floor Systems are inherently durable and trusted to keep people and possessions safe. Prestressed concrete is naturally resistant to corrosion and rot and maintains its structural integrity though extreme conditions. Hollowcore meets fire ratings up to three hours and does not burn, preventing lethal fumes and smoke.
Unmatched Design Versatility
Hollowcore is manufactured to specification and arrives on site ready to install, saving time and cost during construction. County Prestress offers hollowcore planks in depths of 8”, 10”, 12”, and 16”. Our 16” depth plank allows for spans up to 44’ and can be used to create large, unobstructed spaces that are required of parking structures, high-rise offices, multifamily housing, hotels, and other applications. Hollowcore is designed to work alongside other building materials, including concrete masonry, steel framing and cast-in-place wall systems.
