Both Zincalume® and Colorbond® are Registered Trade Marks of BluescopeLysaght Steel and are manufactured here in Australia. Zincalume® is the modern equivalent of galvanized iron with the same silver finish, only longer lasting and much lighter. It is steel coated in a zinc/aluminium/magnesium alloy making it durable, strong and corrosion resistant.
Colorbond® is Zincalume steel with an adhesive, primer and a high gloss colour layer baked onto it. There are over 20 colours to choose from. Both come with BluescopeLysaght’s product warranty and The Roof & Wall Doctor no leak guarantee.
