Updated in 2024, this one-page handout provides a side-by-side comparison of hot-dip galvanized steel (HDG) and uncoated weathering steel (UWS). The analysis includes appearance, inspection, corrosion performance, and much more. In addition, the handout explains the performance of both steels in ISO corrosivity categories common to North America.
