It is estimated that up to four per cent of the world’s GDP is lost through corrosion each year - a fact that makes lifecycle costs a key consideration in many modern construction projects.
Sustainability is also a significant factor when choosing materials and contractors due to ethical decisions as well as enforced regulations.
Hot dip galvanizing has long been seen as the most environmentally-friendly finishing process available to prevent corrosion.
Galvanizing is highly sustainable and produces minimal waste - any zinc that does not instantly form a coating on the metal remains in the galvanizing bath for re-use. The non-ferrous properties of the metal make it indefinitely recyclable without loss of physical or chemical properties.
Galvanized products, once constructed or installed, can also be removed, re-galvanized and re-used. They are also easily recycled with steel scrap in the steel production process.
