Abstract: An awning roller bar or lead bar is formed from a relatively thin material for attachment to the leading edge of an awning. In one embodiment, the roller bar includes at least one slideway having an exterior aperture for receiving and securing the edge of a canopy to the tubing. In another embodiment the roller bar has a plurality of planar walls, a pair of interlocking folds and a substantially triangular slideway. If desired, more than one slideway can be formed in the tubing to provide for the attachment of a screen, valance, sunshade or the like. For reinforcement, an expandable material is injected into at least a portion of the tubing core. The expansion and subsequent stabilization of the foamed material strengthens the tubing to provide a roller bar of rigid construction and light weight.
