Platt Street Bridge Restoration

Hot-dip galvanizing was chosen for this project for multiple reasons, the main one being the corrosion resistance it would provide in the harsh environment where it was installed. Hot-dip galvanizing has also shown it can withstand constant vehicular traffic traveling on it, with minimal degradation. The minimal amount of maintenance required on the decking due to hot-dip galvanizing will benefit the life-cycle costs of the bridge. All of these reasons are what contribute to the ease of specifying this structure to be hot-dip galvanized.

As a major artery, 34,000 vehicles travel across this bridge each day. Every one of these people will see the difference between the old, rusted deck they had been driving over for the past 80 years and the new, hot-dip galvanized deck. Through the years to come, they will behold the evidence of how hot-dip galvanizing resists the corrosive environment of Tampa Bay and the constant traffic across this bridge. Because this grid decking was to be part of a bridge and fit tolerances were very tight, care in galvanizing had to be taken in order to minimize the distortion of each section of grid deck.
