ZINCALUME®

For some things there is simply no equivalent, such as roofing and walling made from lightweight, versatile and durable ZINCALUME® steel. Nothing else has delivered the value, quality and design flexibility of ZINCALUME® steel.

Roofing sheets and wall cladding made from ZINCALUME® steel is available in a range of attractive metal sheeting profiles including concealed fix, corrugated and I.B.R. to name a few. It is lightweight; versatile; attractive and has excellent corrosion resistance.

The coating on ZINCALUME® steel comprises of 55% aluminum, 43.5% zinc and 1.5% silicon. It has excellent corrosion performance, forming capabilities and is available in high strength grades.

ZINCALUME® steel was developed after extensive research into improving the traditional performance of galvanised steel. By blending aluminum with zinc in an alloy coating, researchers discovered a way to greatly enhance corrosion resistance. As a result, our extensive testing programme indicates that roofing or walling made from ZINCALUME® steel lifespan is up to four times than that of galvanised steel with a Z275 coating in the same environment.

BlueScope Steel’s coating mass control technology is amongst the most advanced in the world. A sophisticated coating mass gauge is linked to a computer in a closed-loop control system ensuring accurate control and consistency of coating mass.

More importantly, it gives you the confidence that the award winning material you’ve chosen for your next project will perform today and for years to come.

It’s a design classic. ZINCALUME® steel has the unique ability to compliment both traditional and ultra modern architecture. Use it with confidence. It’s flexible and cost effective, so the design choice is yours. Mill finish galvanized steel and other materials do not have the same satin-smooth finish that is associated with roofing or walling made from resin coated genuine ZINCALUME® steel.
