Nitrogen is widely used in the metal industry such as raw steel cold rolling and galvanizing lines, aluminum refining, and metal heat treatment.

Typical applications are:

• In the cold-rolled steel, with the high-purity of 99.999% nitrogen as a protective gas to avoid steel oxidation

• During the galvanizing process, with a purity of 99.9% nitrogen as a gas knife to ensure uniformity and adhesion
