ZINCALUME® steel is our premium Zinc-Aluminium alloy coated steel, widely
used for roofing and walling applications in the construction industry where long
life is critical.
ZINCALUME® steel was developed as a result of extensive research into
improving the performance of traditional galvanised steel. An alloy coating (55%
Aluminium, 43.5% Zinc and 1.5% Silicon) is applied over the base steel using a continuous
hot-dip process.
The product typically comes with a maximum 150 gram per square meter of metallic
coating with an option of 200 gram per square meter for more severe environment.
The researchers have developed this alloy coating which helps to greatly enhance
the corrosion resistance as compared to galvanised steel.

The excellent barrier properties of Aluminium and sacrificial properties of Zinc
imparts corrosion resistance of upto 4 times that of traditional galvanised steel.
The small spangles of ZINCALUME® steel provide it smooth finish and the
tested surface treatment helps retain its luster for a longer period of time.
High yield strength of the base steel makes ZINCALUME® steel the preferred
option for construction requiring strength and the formable steel grades enable
excellent flexibility in design.

At the same time ZINCALUME® steel is lighter and easier to handle, thereby
making it a better option than conventional building product enabling quick completion
while putting lesser load on the supporting structures.

Roofs and Walls made from ZINCALUME® steel also complement the environment
by way of recyclability, reusability & reducibility.
ZINCALUME® steel is manufactured and supplied as per Australian Standard
AS1397, ISO 9364 and is tested as per ASTM-117 A792M standards.
