ABSTRACT:
A structural member which comprises a pair of hollow end sections and an intermediate web characterized in that each hollow end section is welded to the intermediate web so as to form two weld lines or joins extending along the structural member. Suitably the intermediate web is predominantly planar and the structural member is formed from a unitary sheet of metal having opposed edges whereby a respective edge is located adjacent the intermediate web and is welded thereto form the weld lines or weld joins.
The invention also includes within its scope a process for forming the structural member including the following steps:
