Zinc Aluminium Galvanising Vs Zinc Galvanising
The Decra tile steel core undergoes a high perfomance zinc aluminium galvanisation process which offers a very significant improvement in performance compared to traditional zinc galvanising processes used by lesser quality orientated manufacturers.
The Essential Difference
The benefits of galvanising have been well known for over 100 years and for most of the last century zinc galvanising coatings predominated; therefore it’s only natural for most people to base their performance assumptions of galvanising on their experience with zinc galvanising.
However there is more than one type of galvanising and technology has moved forwards in leaps and bounds. The Decra Roofs System has embraced these advances, all of our roof tiles are manufactured from zinc aluminium galvanised steel; the latest performance advance in galvanising.
How Much Longer Will A Zinc Aluminium Galvanising Coating Last?
Performance tests have shown that zinc aluminium galvanised coating has a much greater life expectancy than zinc galvanising.
Test results have revealed the following performance advantages
- In a rural location zinc aluminium galvansing lasts typically 18.7 times longer than traditional zinc galvanising.
- In a industrial location zinc aluminium galvansing lasts typically 6.4 times longer than traditional zinc galvanising.
- In a moderate marine location zinc aluminium galvansing lasts typically 8.2 times longer than traditional zinc galvanising.
What Is Zinc Aluminium Galvanising Track Record?
Zinc aluminium galvanising was developed by one of the worlds largest steel corporations over 30 years ago. At the time it was seen as a massive breakthrough, but recent field test results have impressed test bodies even more. Since its commercial introduction over 30 million tonnes have been produced and globally 40 steel companies have been licensed to manufacture the product.
