OptigalTM is a zinc-aluminium-magnesium steel substrate specially developed for organic coated products

On January 2014, Flat Carbon Europe launches a new generation of Prepainted steel, made with OptigalTM, a new zinc-aluminium-magnesium alloy specially developed for organic coating. Combined with Granite® or Estetic® finishes,  it offers the most performing and sustainable prepainted steel for the construction.
What is OptigalTM?

OptigalTM is a metallic coating applied by hot dip galvanising of a steel strip in a bath of zinc, aluminium and magnesium alloy.

Improved corrosion protection

Organic coated steel made with Optigal™ benefits from improved corrosion resistance.
A highly compact, stable and protective layer is formed at early stage, leading to a much slower corrosion rate on cut edges and scratches.
All tests show that Optigal™ has a performance that is at least twice better than regular Hot Dip Galvanized.
 

Corrosion resistance rates of OptigalTM compared to regular Hot Dip Galvanized
 
High formability

Organic coatings such as Granite® or Estetic® made with Optigal™ benefit for an unmatched flexibility compared to some competition products.
These paint systems offers the high formability required in most standard forming processes used for construction products: profiling, bending, etc.
Weight reduction

Thanks to a lower density and an inferior coating weight of metallic coating, OptigalTM allows reducing up to 4% the weight of elements compared with traditional hot-dip Galvanized. Mechanical properties remain unchanged thanks to the steel substrate.

Eco-friendly

In the world, every year, five millions tons of zinc are extracted to be used for steels galvanisation while zinc mines resources have a limited life time expectancy.
OptigalTM ensures the preservation of natural resources since it uses less zinc than pure zinc coatings.
By using Nature Granite® and Estetic® made with OptigalTM, you remove all Substances of Very High Concern* from your product line. 
Nature complies with the European REACH Regulation and is always delivered with coatings and surface treatments free of hexavalent chromium compounds and heavy metals.

Where to use OptigalTM?

OptigalTM protective layer offers an unmatched performance for all roofing and cladding applications exposed to harsh environments.
It can be combined with the organic coatings ranges of products Granite® or Estetic® finishes, and deployed in the shape of profiled sheets, cassettes and sandwich panels.
