It is estimated that up to 4% of the world’s GDP is lost through corrosion each year so life-cycle costs are a key consideration in many modern construction projects. Sustainability is also becoming a significant factor when choosing materials and contractors, due to enforced regulations as well as conscious and ethical decisions, to ensure that buildings are as sustainable as possible.
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, as any zinc which does not instantly form a coating on the metal remains in the galvanizing bath for re-use. This is due to the metal’s non-ferrous properties, which makes 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, as well as being easily recycled with steel scrap in the steel production process.
