Prepainted steel has been used for more than 50 years in Europe so ArcelorMittal has had the opportunity to analyse in depth how its products actually behave in situ in different areas. Today we are in a perfect position to assess the effects of time on our prepainted steel. Our integrated production process (from hot strip mill through to coil coating) ensures full traceability and a high level of quality.
The latest innovation in coating systems not only increases the lifetime of construction products, but also reduces their environmental impact. Granite® has become a guarantee of quality, durability and sustainability. Architects, insurance companies, contractors and facade and roofing professionals can be sure of specifying the right product for their projects, with a full guarantee.
The guarantee is automatic: as soon as you buy Granite® you will automatically be covered!
Non-perforation and paint adhesion are the main features to be guaranteed. But for many projects, stability of colour over time is essential to ensure that architectural buildings continue to look attractive and commercial buildings maintain their brand image. This is why ArcelorMittal includes all of these aspects in its guarantee.
The following provides you with the basic details of our automatic guarantee. The full document is available on request.
The choice of coating for roofs and claddings depends on the external environment and the life expectancy.
For industrial or logistical buildings, a 10-20 year guarantee is often enough, but much more is expected for public and residential buildings. To meet all these requirements, ArcelorMittal has developed Granite® HDXtreme. This multi-layer coating system is the universal answer to corrosive environments.

Our automatic guarantees are offered in many countries in Europe, as shown below. Guarantees may also be granted for other geographical zones – do not hesitate to contact ArcelorMittal.
If you buy a Granite® product, a guarantee is automatically granted and does not require any registration. This gives the assurance that your projects and your customers’ projects are systematically protected. Nevertheless, for some applications, locations or environments outside the general guarantee scope, an environmental questionnaire must be completed.
When you buy a Granite® product, you will have access to the detailed guarantee text, which will provide you with all the information you need.
The life expectancy of a building system is much longer than the guarantee period, and can vary depending on many different factors. At the end of the guarantee period, the owner should consider overpainting the roof or cladding to extend its lifetime.
The duration of the guarantee is the same for both roofing and cladding applications.
Some suppliers may make distinctions for non-perforation and non-delamination guarantees according to the colour category. The Granite® automatic guarantee for non-perforation or non-delamination of the paint film is the same whatever the colour.
Yes, the guarantee may be transferred in the event of a change of control of the Beneficiary’s company.

Some specific guarantees can be granted. Ask your guarantee contact for the environmental questionnaire.
ArcelorMittal grants a guarantee to its own customers, but leaves it to the discretion of its customers to give the end user a few years’ additional guarantee, depending on the prevailing conditions where the products are to be used.
ArcelorMittal delivers prepainted steel for roofing profiles with “Granite®” marked on the backing coat. So you can be sure that the prepainted steel used is covered by our automatic guarantee. Always check that the roofing tile profile is made of Granite® before buying it.
