Abstract
A 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.
Claims7
A method of manufacturing galvanized open or closed steel sections, the method comprising a roll forming process followed by a hot dip galvanizing process,
- the roll forming process comprising the steps of:

- after the roll forming process, immersing the formed section in a flux solution, and
- the hot dip galvanizing process not including a pickling or subsequent rinsing step.
A galvanized open or closed steel section formed in part by the method of any one of the preceding claims.
