Abstract

Abstract A security panel system which may be assembled into security panels, having at least one pan member with interlockable ribs for formation of continuous, interlocking pan surface, at least one channel member having a web, a first flange and a second flange having at least one notch for passage of pan ribs therethrough for attachable abutment of the pan ribs against the first flange and at least one trim member attachable to the channel member, for placement against the pan member so that the pan member is captured between the channel member and the trim member. A pair of channel members may be combined along their webs to form a carrier member having pairs of first and second flanges that are oriented opposite each other.
