ABSTRACT:
A structural arrangement is provided which is particularly useful in connection with solar greenhouses. The structural member is provided as a hollow bar of elongated form provided with at least one longitudinally extending track channel having a relatively narrow longitudinally extended slot-mouth. The bar may be provided with two such channels substantially circular in cross-section with the mouths defining reentrant angles. In a solar greenhouse, members of the above type support a glazing with a curved-eave section, the bars being curved to shape and the channels therein accommodating the bulbous lateral edges of shades which are retained therein.
