Hot dip galvanizing corrosion map

This map provides data for the atmospheric corrosion rate of hot dip galvanizing. Search for a location and hover over the 10 km grid to obtain the corrosion rate. The map legend can be used to find the average life of an 85 µm coating within the area.

Corrosion rate key
Average Corrosion Rate(µm/year) 0.5 1 1.5 2 2.5
Average Life of 85µm galvanized coating(years) 170 85 57 43 34

Average background corrosion rates for zinc. Each grid square is 10km².
