Heritage Water Tanks have an attractive, strong, durable and engineer certified steel wall, with the option of either a Corrugated or Streamline profile. Every Heritage Water Tank uses Australian BlueScope Steel.
BlueScope ZINCALUME® steel, has been proven to be longer lasting than galvanised steel, because the coatings on galvanised steel and ZINCALUME® steel perform in different ways. ZINCALUME® steel has much better corrosion protection (and service life) than galvanised steel.
Side by side exposure testing has shown corrosion protection provided by ZINCALUME® steel with an AZ150 (150g/m2 ) coating mass is far superior to that provided by galvanised steel with a Z275 (275g/m2 ) coating mass.
The tests demonstrated that ZINCALUME® steel corrosion protection can last at least four times longer than the corrosion protection provided by traditional zinc coated steels in roofing and walling applications in identical environments.
