Hollow Core Panels
About Hollow Core
Great Lakes Superior Walls is an exclusive distributor of Hollow Core Panels that are precast, prestressed units with excellent fire resistance, increased durability, and reduced self-weight.
Hollow Core allows for a fully functional living space underneath your garage floor.
Ideal for flooring and roof systems, Hollow Core panels are a precast, prestressed concrete solution designed for strength, speed, and versatility. Each panel contains continuous hollow voids that reduce weight without sacrificing structural integrity—allowing for longer spans, faster installation, and more efficient construction.
Made from prestressed, high-strength concrete for superior load capacity and long-term performance.
Machine-extruded and cut to custom lengths, typically in 4-foot-wide sections, for accurate fit and minimal waste.
Available with an exposed “loft look” or smooth, ready-to-paint surface.
The hollow-core design makes panels easier to transport and handle, reducing installation time and equipment needs.
