Granite® Prepainted steel for outdoor building
DESCRIPTION
ArcelorMittal’s organic coated Granite® range comprises a series of organic coated products, covering all possible applications for the outdoor building market.
The grades of the steel substrates available, combined with the properties of the Granite® coating, make these products attractive alternatives that meet all the requirements of the construction sector:
- aesthetic quality
- flexibility
- surface hardness
- coating adhesion
- corrosion & UV resistance
|
The substrate for Granite® are galvanized steel, or other metallic coated steels with a layer of flexible paint on two sides consisting on an anticorrosive priming lacquer and a high or very high-durability resin.
There are three surface appearances:
- smooth (HD, Farm, HDS models)
- matt (HDS model) or
- grainy (HDS and HDX models)
Backing Coats
Granite® is available with backing coat. It offers a full range of specific properties: foam adherence, mechanical properties, corrosion resistance. See the backing coat data sheet:

MAINTENANCE AND GUARANTEE
Maintenance
A natural wash of the organic coated surfaces by atmospheric rainfall shall normally be assured in order to prevent any clogging that may be detrimental to their appearance (dust deposits etc).
For walls and roof surfaces that are not naturally washed by rainfall, regular maintenance is compulsory, with the following minimum frequency:
- An annual washing without the use of abrasive or aggressive products;
- Systematic and immediate treatment of any parts that, for various reasons, show initial signs of corrosion.
