This range of Granite^® organic coated steels is designed for outdoor applications for the building market and comprises a number of speciality products. These products meet all the requirements of this market in terms of original surface finish and end-use properties.

Designed by ArcelorMittal for specific applications, the Granite^® products in this range meet rigorous requirements in terms of aesthetic quality, flexibility, surface strength, chemical and UV resistance etc. 

Various paints are applied to a metallic substrate as part of a continuous process, which ensures optimum adhesion of the coating and improved corrosion resistance of the steel.

A wide range of colours and different original surface finishes are proposed, depending on the end use envisaged.

Granite^® Flex, Granite^® Deep Mat, Granite^® Quartz, Granite^® Storm and Granite^® Impression Cloudy & Wood products have an original surface finish and very good flexibility, which is particularly recommended for metal roof tile applications. The surface appearance of these coatings can be smooth or grained (Granite^® Flex, Granite^® Impression Wood for some colours and patterns), structured and matt (Granite^® Deep Mat, Granite^® Quartz and Granite^® Storm) or bicoloured (Granite^® Impression Cloudy).
 
Granite^® HFX Cool has been designed for constructing standing seam roofs in low temperatures, in the cold environments encountered in Northern and Eastern Europe.
 
Granite^® Rain HDS and HDX, with a double-sided finish, are intended for rainwater systems such as gutters, drainpipes and accessories.
 
Granite^® Tex has a strong, textured surface highly suitable for applications such as switch boxes and air conditioning units.
 
Granite^® Farm has been specially designed for the internal surfaces of cladding and roofing to be used in ventilated agricultural buildings for cattle, poultry, grain storage etc.
 
Granite^® PVDF is dedicated to cladding and roofing applications for architectural buildings or buildings exposed to harsh environments where good coating stability is required.

Automatic guarantees can be granted for Granite^® range products used in exterior cladding or exterior roofing of buildings located in Europe.

These Granite^® products can be processed by cold forming and deep drawing without damaging the top surface. They can be joined using techniques such as clinching, riveting and adhesive bonding.

These organic coated steel products are used for their wide range of technical properties, which depend on the chemical composition and thickness of the paint, the appearance of the coating and the type of substrate. This range of organic coated steels includes a suitable product for every application. The choice of the paint system depends on the technical requirements during processing and specific end use in terms of flexibility, UV, corrosion, abrasion and chemical resistance. Products used to make tiles are thus designed to enable very deep drawing, without damaging the coating. Being very flexible, they can withstand small profiling or drawing radii.

The substrates used for these applications are galvanised steel or galfan. The choice depends on the end use and the required corrosion resistance.

A temporary removable protective film can be applied on the top side of some products in this range (except for wrinkled surfaces).

The technical properties are summarised in the table below. Please contact us for advice on the choice of the most suitable grade for your application.

These products are in compliance with standard EN 10169.

These products are available with a wide range of mechanical properties, depending on the substrate used and the intended application. See properties of the different substrates.
