PCT No. PCT/AU93/00488 Sec. 371 Date May 30, 1995 Sec. 102(e) Date May 30, 1995 PCT Filed Sep. 22, 1993 PCT Pub. No. WO94/08064 PCT Pub. Date Apr. 14, 1994A method of manufacturing galvanized open or closed steel sections eliminates the steps of pickling and rinsing. The manufacturing process is modified in such a manner that shot blasting of both sides of a strip of substantially flat steel occurs prior to a forming step in the process. After the forming process, the formed section is immersed in a flux solution.
