Zinc is very malleable, which means increased design flexibility and enables the inclusion of such additions as sprung curves and bull nose shapes.

 

Maintenance costs are low, as zinc develops a protective zinc carbonate layer or patina as it weathers and ages. This eliminates the need for paints and other protective coatings.

 

Because the metal is uncoated, there is no possibility of fading, chipping, peeling or chafing, which considerably reduces overall life cycle costs.

 

Moreover, as the patina forms, any scratches or imperfections in the metal tend to disappear.

 

Zinc is a popular metal to use for eco-building projects for its properties. It is 100 per cent recyclable, plus it uses a smaller amount of energy to produce than other metals, so impacts less on the environment. The water run-off from zinc does not pick up any additional chemicals that will taint any potential groundwater supply.
