Abstract
Construction elements of predetermined cross-sectional and end profiles are formed. These construction elements are useful in building construction. Included in an I-shaped element, a corner/connecting block and a D-shaped profile material. In addition, end cuts may be provided to provide interlocking assembly of the different elements, to establish a family of parts. The element can be pre-cut to desired lengths and assembled as kits, or as raw material, for use in all aspects of construction. Further included is a substantially C-shaped element which provides structural strength as well as distinctively different aesthetic aspects of construction.
