The pickling process has no influence for the mechanical properties of the steel materials. But for the high tensile steel above 80KG/m2, hydrogen evolution action is liable to appear. It needs the galvanizer to pay attention. Nevertheless, there is still no experimental assertion for any harmful influence.

The galvanizing process has some mechanical property influences for the high tensile steel 60kg/m2，but the influence is within the tolerance of quality standard.

Other galvanizing process have no influences on the mechanical properties.
