When looking at a roofing solution for your home, you would want to know what exactly it consists of, and be assured that it’ll stand the test of time. At Tilcor, we use ZINCALUME® steel in all of our roofing systems, a highly durable material which allows complete traceability for the ultimate assurance of quality.
In this blog, we’re going to look at the benefits ZINCALUME® steel has over galvanized steel, and why it’s a product that’s going to go the distance for your home.
Our steel is coated in a protective layer of zinc to prevent it from corroding and rusting. The zinc works as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected from the elements by the zinc.
THE KEY BENEFITS OF ZINCALUME® INCLUDE:
- Good corrosion resistance at high temperatures
- Good abrasion resistance due to the hardness of its surface
- Excellent thermal and light reflectivity
- ZINCALUME® has a significantly longer service life than a galvanised steel product
ZINCALUME® VS. GALVANIZED STEEL
ZINCALUME® has a significantly longer service life than a galvanised steel product that uses only zinc. In fact, various corrosion tests have shown that the surface corrosion resistance of ZINCALUME® is almost twice as good as Galfan. This is due to the higher proportion of aluminium in the coating - a material which reduces its reactivity (Galfan only has 5% aluminium).
Galvanization only applies a protective zinc coating to steel. Although galvanizing will slow the attack on the underlying steel, rusting will be inevitable after some decades of exposure to weather. For example, corrugated iron roofing will start to degrade within a few years despite the protective action of the zinc coating.
OUR ZINCALUME® IS 100% NEW ZEALAND SOURCED
ZINCALUME® is produced by New Zealand Steel Limited, our country’s sole steel producer. They use locally sourced iron-sand, and manufacture a range of flat steel products for the building industry. And you can be confident they're manufacturing responsibly with their fully integrated steel mill at Glenbrook having gained approval from Environmental Choice New Zealand.
THE MARK OF QUALITY
The quality of our stone-coated steel roofing panels can actually be seen on the underside of the panel. All Tilcor panels are printed with the Ross Roof Group logo, batch number, date and certification markings for ultimate traceability and quality assurance, such as CE Mark, Miami Dade, BBA.
Your roof is an integral part of your home, so it’s vital to be aware of the materials you're using and where they come from. Our ZINCALUME® steel coated panels are a phenomenal material that offer the best of both worlds - durability and a stunning aesthetic.
