Duradek

Duradek is a new material for roofing and cladding that has been developed for customers looking for a more economical solution.

It is a material produced with Zinc-Aluumium Alloy Coating with an attractive color finish. However, Duradek has a lower coating class than Colorbond and Zincalume.

As depicted in the figure 4.2, the Duradek steel is coated with Zinc-Aluminim alloy coating (AZ 70) with a lower class grade than of Colorbond and Zincalume material. Another layer of conversion coating is applied on the surface to enhance the resistance to early corrosion and the high gloss finish coating gives the Duradek a smooth and satin finish.
