What is the construction of a floor panel?

There are various basic floor panel constructions that are outlined below along with various attributes of each type. 

Steel encased woodcore. This panel construction comprises of a high density particle board core that is encased by galvanized steel laminated to the particle board by a structural polyurethane or epoxy resin adhesive. This construction type is capable of providing high strength and good fire and acoustic performance. By varying the thickness of the steel sheet and the strength of the chipboard core a wide range of structural performance is available. 


Steel/cementitious panels. Here a structural steel shell comprising of a flat steel top and a profiled steel base are welded together to form a hollow shell. This shell is then filled with a foamed cement based core to give a panel that gives good structural performance in conjunction with excellent fire performance. In certain cases the hollow unfilled steel shell will provide a floor panel that gives suitable structural performance although its acoustic performance is limited.
