An elongated, light weight, maintenance free, hollow structural support post or column for supporting an overhanging roof segment in spaced relationship to a porch floor, for example. The post comprises a thin walled, generally rectangular plastic member containing a circular, metal tubular member therewithin, and spaced from the inner wall of the plastic member by plural elongated, plastic inserts press fit between the metal tubular member and inner wall of the rectangular plastic member. Additionally, the invention includes a pair of uniquely designed end base plates for anchoring the post to the overhanging structure and to the porch floor, where the base plates cooperate with the metal tubular member to prevent twisting of the post when maintained in a compressive or supporting mode.

The light weight, hollow structural support column according to claim 1, wherein said plastic member comprises a thin walled body and fabricated of polyvinyl chloride (PVC). 3. The light weight, hollow structural support column according to claim 1, wherein said circular annular flange is angled inwardly to facilitate the sliding engagement of said circular annular flange into said circular tubular member. 4. The light weight, hollow structural support column according to claim 1, wherein said circular annular flange includes an upper surface, said surface defined by a scalloped profile. 5. The light weight, hollow structural support column according to claim 4, wherein said planar base includes a first surface from which said circular annular flange extends, and said first surface includes a series of radially extending ribs projecting outwardly from said circular annular flange. 6. The light weight, hollow structural support column according to claim 5, wherein said metallic tubular member is fabricated of aluminum, and said base plate is fabricated of steel. 7. The light weight, hollow structural support column according to claim 6, wherein in an operable supporting mode said aluminum tubular member is deformed in compressive contact with said radially extending ribs to fix the relative position of said tubular member to said rectangular plastic member. 8. A light weight, hollow structural support column, said support column comprising: a.) an elongated, hollow, generally rectangular plastic member having an inner wall; b.) a circular metallic tubular member extending the length of said rectangular member and centrally disposed therewithin, and having an outer wall; and, c.) a plurality of elongated U-configured plastic inserts extending between said inner wall and said outer wall, said plastic inserts having a base in intimate contact with said outer wall, and a pair of free arms, each said arm terminating in a laterally extending wing member with said wing members in intimate contact with said inner wall.
