  • Patent number: 4991364
    Abstract: A structural member can be used alone or paired with a like member for use as an upright or cross member of a support structure. This structural member has particular application in greenhouse structures where a support structure is formed for retaining transparent panels. The structural members are preferably made of rolled steel and are of a generally `T` configuration with a pair of retaining flanges. The structure simplifies manufacturing by accommodating punching of various fastening ports or forming of securing flanges prior to the rolling operation. Any shaping of the members is easier as the shaping may be carried out on individual members prior to pairing of the members to form an upright or cross member.
