Performance and Durability
You can use ZINCALUME® steel with confidence. It's easy to paint, handle, store and install, with corrosion resistance that's up to four times greater than that of ordinary galvanised steel.
Extraordinary Mark Resistance
The resin coating on ZINCALUME® steel provides excellent mark-resistant qualities. For the rollformer, roof fixer, builder or manufacturer, marks from sweaty hands or moisture are a thing of the past. Boot and scuff marks are virtually eliminated. The result? A better looking product for the consumer.
Look for the branding that identifies the long-lasting guaranteed performance of genuine ZINCALUME® steel.
Meets Australian Standards
ZINCALUME® steel is manufactured to the most stringent production standards to ensure the product's superior performance and long life. It meets Australian Standards (AS1397-1993) and is backed by BlueScope Steel's guarantee of quality. So when you ask for ZINCALUME® steel, you can rest assured you're specifying the best.
Installation and Storage
When installing ZINCALUME® steel, nails, rivets, swarf and metal filings must be removed at the end of each day's work. Lead or copper based are incompatible materials that may induce corrosion where moisture or condensation are present. Leaves, dirt, timber and rags should not be allowed to accumulate on the sheet surface. They can also retain moisture and release corrosive materials. Although the resin coating on ZINCALUME® steel minimises wet stack storage staining problems, it's good practice to keep ZINCALUME® steel dry in transit. Store it clear of the ground and under cover. If packs should become wet, wipe the sheets dry and allow air circulation to complete the drying process.
Ease of Fastening
When it comes to fastening, ZINCALUME® steel can be bent, folded, stamped, punched or crimped. Integral fastener systems include seam, tab and recess and extruded interlock systems. For pierced fixed applications we recommend fasteners that comply with AS3566.
A Joint Effort
The best sealed joints for roofing and rainwater products are made by using neutral-cure silicon sealants in conjunction with mechanical fasteners such as blind rivets. For more information on recommended sealants, contact your sealant supplier.
Compatibility
The compatibility of ZINCALUME® steel with other materials is similar to that of the traditional zinc-coated steel sheet. The exceptions are lead, copper and stainless steel which can cause corrosion of the coating. Lead washers, lead-headed nails and lead flashing should not be used.
BlueScope Steel's Two Way Protection System
ZINCALUME® steel protects the steel base in two ways. Firstly, the aluminium component of the coating provides a tough physical barrier between the extreme atmospheric conditions and the inner core of steel. Secondly, the zinc in the coating protects the steel at cut edges and scratches. Galvanic action causes zinc compounds to automatically build up at cut edges and around scratches through an electrolytic reaction when water or moisture is present. It slows the rate at which the surrounding coating is consumed around exposed areas. This effect is sometimes referred to as the 'self healing' property of coatings containing zinc.
Atmospheric Testing Proves Four Times Longer Life
Atmospheric exposure tests confirm in correct application, the corrosion resistance of ZINCALUME® steel is far superior to that of ordinary zinc coatings, lasting up to four times longer in an identical environment.
BlueScope Steel's intensive research and development process includes real-life testing sites that have been in operation for decades to constantly monitor product performance.
