ABSTRACT:
A self supporting header has a horizontally extending header pipe of fiberglass reinforced plastic with a horizontal axis and a flange of fiberglass reinforced plastic connected to an outer surface of the header pipe by at least one web and extending along at least part of the horizontal extent of the header pipe. The at least one web extends vertically from at least one of the top and bottom of the header pipe and is connected to the flange. A reinforcing member or material is embedded in at least one of the flange and the at least one web and that has a greater modulus of elasticity than a modulus of elasticity of the fiberglass reinforced plastic of the header pipe reinforces a cross-section of the header for increasing the self supporting strength of the header. The reinforcing member may be made of metal or a carbon composite material.
