Raised floor panels

摘要

The invention relates to raised flooring panels which have excellent fire resistance. The panels of the invention comprise wooden panels whose undersides and side edges are covered with a metal sheet, and the panels being strengthened by downwardly projecting metal flanges. Such a panel can have better fire resisting properties than a metal panel which is liable to warp when there is a fire and which conducts heat to its upper surface so that floor coverings rapidly reach their flash point or than a wooden panel whose underside but not side edges are covered with a metal sheet.
