One of the most important issue
for the for plan maintenance engineers and managers is how to overcome the cost
of investment in corrosion protection system. The possible answers range from
painting, hot dip galvanizing or using protective coatings against corrosion. All
these process not only involve performance evaluation but also initial and life
cycle cost analysis. Mostly zinc metals
are used to hot dip galvanize steel for more than 250 years, providing strong protection
against corrosion in many environments for 50-70 years and its successfully being
used in Industrial galvanized steel beams to prevent them from corrosion.
The imperial Data collected
from the field performance of hot dip galvanized steel from 1940 to 1980 in
industrial and manufacturing settings indicate that zinc prevents corrosion of
base steel to be used for Columns, handrail, gratings, and expended metals
because there are no maintenance cost. Initially it was thought that hot dip
galvanizing steel is more expensive than other systems in protecting from
corrosion but when it was used practically engineers came to know it is the one
cost effective method of preventing metals from getting rusty.
