- All surfaces of the steel are galvanized, whether they are visible, hidden, external or internal.
- Unlike most other coatings the galvanizing is bonded metallurgically to the steel through the formation of Iron and Zinc alloys.
- The galvanizing forms a barrier stopping the steel from reacting with the environment.
- The galvanizing also provides sacrificial action if the coating is damaged, with the zinc sacrificing itself to protect the steel below. This is due to zinc being more active than steel in the metal reactivity series.
- Galvanizing can last for well over 100 years depending on location. To find out how long galvanizing will last in your area click on this link. Zinc Millennium Map
- The coating is available in as little as 24 hours.
- The tough nature of the coating ensures minimum packaging and protection leading to speedy erection on site.
- Galvanizing is a tough, abrasion resistant coating that provides resistance to mechanical damage during transit and erection.
- The alloy layers formed next to the steel are harder than the base steel itself.
- The softer zinc top layers absorb much of the shock from handling impacts.
- The initial cost of galvanizing will be comparable to a two coat paint system but when the whole life cost is taken into consideration galvanizing can work out to be substantially more cost effective. This is due to galvanizing being maintenance free therefore eliminating the requirement for maintenance repainting.
- The longevity and maintenance free nature of galvanizing reduces the energy demand of structures in the built environment.
- Waste energy and by-products from the galvanizing process are recycled to be used in other parts of the process and other industries.
- Little or no packaging reduces the waste that is generated.
