Based on HERA Report R4-133:2011

The cost of hot dip galvanizing is extremely competitive particularly for small to medium sized structural members.

Unbeatable value over life-of-asset

When you consider life of asset value, hot dip galvanizing is in a class of its own, delivering accumulated maintenance cost savings that is unmatched.
