Pearl Harbor serves as a major homeport for the submarines and surface ships of the U.S. Pacific fleets. The surrounding security barrier system was designed to protect the east loch of the harbor and stop over 99% of likely threat watercraft. Hot-dip galvanizing ensures the barrier will withstand the harsh, corrosive marine environment, and also provides a coating durable enough to endure constant motion from the waves.

The tough barrier coating created by the metallurgical bond developed during the galvanizing process is also resistant to contact with vessels and any wildlife that comes into contact with it. The performance provided by hot-dip galvanizing optimizes the life of the barrier with less required maintenance, making the units have only a 5-year maintenance schedule despite being subject to a harsh marine environment. The durability of HDG in such a corrosive environment will provide strong protection for this barrier, enabling it to protect the harbor against any future threats.
