The £175 million bridge’s concrete structure will be coated in a copper-nickel alloy, known as cupro-nickel, from its feet on the riverbed up to the base of the balustrades on the bridge deck.
In a statement the trust said the copper, which has been donated by from multi-national mining company Glencore, was a ‘fundamental’ part of Heatherwick’s concept for the bridge.
The material will form a protective skin to the carbon steel structure giving it a maintenance free 120 year life, protecting the bridge from river and environmental corrosion.
More than 240 tonnes of the material - which is commonly used for medical equipment and ship propellers - will be used on the scheme.
Glencore’s donation brings support for the bridge to £120 million. The Trust plans to launch a public fundraiser later this year to help raise the final funds needed for the scheme.
