Abstract
The invention comprises a two-part support member for curtain walls capable of withstanding the extreme loads required for extra-large walls with minimal deformation comprising two independently extrudable components, each of which may be produced on standard extruders and attachment means that holds the extrudable components together. The sections fit together in such a way that inevitable deformations that occur during production are taken into account and corrected for. Due to the hitherto unattainable stiffness values that this combination of components may reach, extra-large curtain walls mounting and supporting is achieved that was otherwise unattainable. The cross sectional area of the sections is relatively small allowing for lightweight members to be extruded that use a minimum of material.
