Granite^® Rain: the cure to 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’re difficult to form, frustrating to use and easily susceptible to corrosion. And let’s not even get started about aesthetics! Gutters are either grey or white and could 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
• Beauty
• Cost-effectiveness
• Ease to use
• Outstanding corrosion resistance
• Colour stability

– this is the Granite^® Rain story.

Thick to resist

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:

• Granite^® Rain HDX: 55 microns of total paint thickness
• Granite^® Rain HDS: a 35 microns paint coat

The unique paint coat is also a protective layer against the fading effects of UV rays.

Easy to use

The challenge with creating a thick, durable gutter is that you lose flexibility. 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 the right for your project?

The choice between the two products depends heavily on the environmental conditions of the location that the product will be exposed to. This is a crucial decision and should be made in close collaboration with ArcelorMittal’s technical experts and account managers.

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 specifically 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.
