Painting Vs Galvanising

For over 150 years, HDG has been used all around the world testifies its reputation for reliability. Numerous research papers have shown HDG is more superior than painting in many aspects. HDG metallurgically bonds zinc to steel, and is not just a coating like paint does. Because of this bonding, HDG can last many years longer without the need for costly maintenance. Below are some examples of HDG vs Paint:

Environmental impact studies based on "Life Cycle Assessment" (LCA) methodology have demonstrated HDG's more favourable status compared to conventional paint system. It requires zero maintenance during the practical service life of most galvanised structures. This translates to zero labour or transportation of labour cost to the repair site, zero energy cost, zero emissions and zero material wastage for repairs.
