ConCore™ access floor panels are epoxy coated unitized shells. The shells consist of a flat steel top sheet welded to a formed steel bottom sheet. The panels are then filled with a highly controlled mixture of lightweight cement. Manufactured to exact tolerances, these non-combustible, rigid panels deliver the ultimate in design, performance, plenum integrity, service, and usability. There are seven panel grades that meet all Tate Standards and CISCA Testing Requirements, as well as Australian Standards (ConCore™ 800, ConCore™ 1000, ConCore™ 1250, ConCore™ 1500, ConCore™ 2000, ConCore™ 2500, and ConCore™ 3000) and an extensive selection of understructure supports to meet specific performance requirements. The understructure includes two different support structures for different load requirements including Bolted Stringer and Cornerlock.
