Perhaps the most critical choice made in the design of fabrication connections is how to protect the fasteners from corrosion. The protection of fasteners is imperative, because if the fasteners corrode and fail, the integrity of the structure is at risk. Hot-dip galvanizing (HDG) delivers long-term, maintenance-free corrosion protection of fasteners, thus eliminating the concern. Whether used in atmospheric, concrete, soil, or water (fresh or salt) applications, hot-dip galvanized steel provides maximum time to first maintenance. Additionally, because of galvanizing’s maintenance-free quality, there will be no difficult field repairs nor labor and material costs associated with those repairs.

So, why hot-dip galvanize? The answer is in the many benefits hot-dip galvanized fasteners provide. The following information will explain how and why hot-dip galvanized fasteners provide superior protection for connections, as well as some design considerations when using galvanized fasteners.

Revised in 2009,  this publication provides detailed information on hot-dip galvanized fasteners including performance, design considerations, and benefits of galvanized fasteners.
