Hot Dip Galvanizing
Proven, Honest, Sustainable
Hot Dip Galvanizing has protected steel across UK and Ireland for more than 150 years. It bonds itself metallurgically to steel imparting toughness and abrasion resistance through its alloy layers. Its unique characteristics help provide a long maintenance free life for steel.
Up to 170 years of protection

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 |
