By protecting steel from corrosion, hot dip galvanizing performs an invaluable service. It helps to save natural resources by significantly prolonging the life of steel and capital investments. The long-term durability provided by hot dip galvanizing is achieved at a relatively low environmental burden in terms of energy and other globally relevant impacts, especially when compared to the energy value of the steel it is protecting.

Durability and Service Life

Zinc is the 24th most abundant element in the Earth’s crust and has been present ever since the planet formed its surface. It is an essential mineral of “exceptional biologic and public health importance” and is considered a “Life Saving Commodity” by the United Nations.
 
Zinc moves constantly throughout the environment by a process called natural cycling. Rain, snow melt, ice, solar heat, and wind erode zinc from rocks and soil. Wind and water carry minute amounts of zinc to lakes, rivers and the sea, where it collects on organic material and eventually settles into the sediment. Other natural phenomena, such as volcanic eruptions, forest fires, dust storms and sea spray, contribute to the continuous cycling of zinc.
