Abstract: A profiled panel (10) is disclosed. The profiled panel (10) is formed from sheet material. The panel (10) has a plurality of fixed longitudinally extending formations (12) that provide one or more base characteristics of the panel (10), and at least one variable longitudinal formation (22). The variable longitudinal formations (22) are arranged to vary from one panel to another panel. This enables the variance of a width dimension (28) of the panel (10). A profiled panel is also disclosed that includes at least one edge member which is profiled to receive and/or form part of said wall fixture.

Abstract: A method of fixing overlaying components together, comprising the step of piercing nails having a profiled shank through the components to fix those components together. Structures including metal sheet are also disclosed which utilize this fixing technique. The structures include composite wall panels used in tilt up wall panel construction.

Abstract: A panel comprising one or more decking members is arranged such that a settable material can be supported thereon to form a composite panel. The panel further comprises one or more elongate strengthening elements, each element being arranged to connect to the one or more decking members in a manner such that the one or more elements increase panel strength.

Abstract: A composite panel comprising a layer of hardened settable material, at least one element bonded to and/or embedded in the settable material, and one or more connectors fixed to the at least one element, the or each connector comprises a coupling portion that is disposed at a surface of the panel and arranged to form one part of a load bearing coupling, wherein loading induced at the coupling is arranged to be transferred through the connector to the element.
