Abstract: A suspended ceiling system for use in a cleanroom or other application incorporates a framework formed from lengthwise and crosswise frame members which form open areas for mounting components such as air filter modules, light fixture panels, blank panels and the like. The ceiling system includes splice members for connecting the frame members together and clamps for securing the components to the frame members. Suspension members, which preferably engage corresponding fastening members disposed within the frame members, suspend the framework from the ceiling, defining an interior space above the framework. Substantial loads, such as utilities, robotics and wall partitions may be suspended from the framework by clips that engage with the frame members.

Abstract: A composite floor panel suitable for use in access or elevated floors comprises a surface plate and a base plate which may be manufactured from plastic and joined together by an adhesive. The top surface of the panel may be adapted to receive a preselected finishing material including carpeting, vinyl or any of a number of other commercially available wear surfaces. The composite panel is lightweight, does not require a conventional edge trim and may be adapted for use with conventional access floor support systems.
