Granite® Rain: the cure for the standard gutter
Every builder has at some point dreamed of a quality gutter that is durable, easy to use, cost-effective and – perhaps above all else – aesthetically pleasing. That is because the problem with gutters is they serve a specific purpose with little interest in anything else. The gutter was born to carry rainwater away from a structure.
They are difficult to form, frustrating to use and far too susceptible to corrosion. And we have not even mentioned aesthetics yet! Gutters are either grey or white and could not care less about complimenting your structure. It is time to stop dreaming and to discover Granite® Rain.
A new kind of gutter
Granite® Rain is all about the unique. It is unique in its double-sided organic coated paint systems. It’s unique in that it is intended specifically for rainwater systems and their accessories. Its automatic guarantees against perforation and peeling are unheard of. And the available colour palette that stretches from grey white to copper brown and all the way to jet black ensures it will aesthetically blend in with all components of a structure. Said simply, quality and cost-effectiveness, outstanding corrosion resistance and colour stability – this is the Granite® Rain story.
Extra durable coating
ArcelorMittal set out to create a gutter that can stand up to the elements while maintaining its colour for years to come. To do this, Granite® Rain utilises a breakthrough level of paint thickness on each side of the gutter. The thickness of the paint creates an armour-like barrier between the elements and the actual steel, optimising it for weathering resistance. Granite® Rain comes in two variations of thickness. The HDX version offers 55 microns of total paint thickness, while the HDS offering a 35 micron coating ensures that it withstands the ever-present threat of corrosion, perforation and peeling. The unique paint coat is also a protective layer against the fading effects of UV rays.

Easy to use
The challenge with creating a strong, durable gutter is that you lose fl exibility. Here again, Granite® Rain breaks from tradition and exceeds expectations. ArcelorMittal’s innovative layered design is remarkably easy to use. Unlike the rigid design of typical gutters, Granite® Rain HDX is extremely flexible and can even be processed at low temperature.
HDX or HDS?
Granite® Rain HDX and Granite® Rain HDS correspond to two different coating systems. Their thickness and performance are specifically optimised for rainwater system applications, providing a high weathering resistance and enhanced moisture barrier effect. So which one is right for your project?
The choice between the two products depends heavily on the environmental
conditions of the location to which the product will be exposed. This is a crucial decision and should be made in close collaboration with ArcelorMittal’s technical experts and sales teams.
Although both products have shown outstanding performance in weathering tests, as indicated by the classification obtained according to EN 10169 standard, Granite® Rain HDX has some additional advantages. For example, Granite® Rain HDX’s unique coating gives the organic coated product a high level of flexibility, even in cold climates.

A palette of colour
Traditionally, gutters are seen as a necessary evil and therefore the design tends to favour durability over the aesthetically pleasing. Granite® Rain asks ‘why can’t we be both?’ The answer is ‘yes you can’, as Granite® Rain comes in a variety of colours to suit every taste and every budget. More so, knowing that no two projects are the same, customisation is also available.
All colours have an artistically grained aesthetic appearance and are put through ArcelorMittal’s common quality assurance system at the mill, guaranteeing that diversity and originality will be the trademark of every project.
More than just good looks
Granite® Rain’s aesthetics is more than just colours. These colours are brought to life with its unique grained texture that not only gives the gutters an artistic touch, but also serves as an additional level of protection. The grained surface texture is designed specifi cally to resist normal wear and scratching, making it even easier to handle.
The Granite® Rain Guarantee
It looks good, it’s durable, flexible and easy to use. What more can you ask from a gutter? How about an automatic guarantee? Each product is guaranteed against oxidation-induced perforation of the metal support caused by a material defect and against delamination. ArcelorMittal further guarantees the aesthetic appearance of the exposed side of the product. This guarantee covers uniform ageing of the colour for the same exposure and the same rainwater system element.
If the product shows signs of defect in more than 10% of the total external system within the specified time (10 years for HDS, 15 for HDX), then ArcelorMittal will either replace or reimburse the product or repaint the defective surfaces.
Combining durability with ease of use, flexibility, a guarantee and opportunities in aesthetics, ArcelorMittal’s Granite® Rain products redefine rainwater systems – taking it ‘out of the gutter’ and into the overall design of the structure.
