Aluzinc® is a flat carbon steel coated with an alloy comprising 55% aluminium, 43.4% zinc and 1.6% silicon. Aluzinc® has the advantage of a long lifespan in many environments, especially in the construction sector. Its excellent corrosion resistance is the result of the properties of aluminium, present on the surface of the coating, and zinc. While aluminium-zinc alloys offer the best possible durability, a few guidelines do need to be followed in terms of building design and on-site practices in order to optimise product performance. The following instructions therefore constitute the key recommendations for ensuring that your project can take full advantage of the exceptional durability of Aluzinc®.

2.12.12.12.1 TransportationTransportationTransportationTransportation

A closed, tarpaulin-covered truck is strongly recommended for transporting Aluzinc® sheets. The sheet steel must be properly strapped, possibly film-wrapped and placed on a palette during transportation in order to prevent any damage (water penetration, impact, indentation etc). This applies particularly to sheets intended for façades. Care should also be taken to avoid placing other materials on the stacks of sheets.

2.22.22.22.2 Unloading on siteUnloading on siteUnloading on siteUnloading on site > When the sheets arrive on site, unload them carefully (if possible using specialised machinery, as pictured below), without knocking them or placing them directly in contact with other materials. > Leave the protective film on and maintain the same stacking of the sheets as during transportation.

2.32.32.32.3 Storage of sheets on siteStorage of sheets on siteStorage of sheets on siteStorage of sheets on site

The sheets must be kept dry, if possible in a sheltered and enclosed area, protected from any humidity and openings (increased risk of corrosion or even black rust for Aluzinc® without surface treatment) and from overexposure to sunlight (which would subsequently make it more difficult to remove the film, thereby increasing the risk of marks). Storage and transport conditions must be the same: covered in tarpaulin, strapped and placed on palettes or stringers.

If it is not possible for you to store the Aluzinc® sheets in a covered shelter, adhere to the following recommendations to avoid any nasty surprises:

1111

• Cover the sheet stack with a thick tarpaulin in good condition.

• Ensure there is an air space at ground level, between the tarpaulin and the bottom of the stack.

2222

• Store the stack of sheets up off the ground.

• Incline the stack slightly to allow any rainwater or condensation to run off.

3333

• Check regularly that no moisture has penetrated under the tarpaulin or between the sheets.

• Visible roofs:Visible roofs:Visible roofs:Visible roofs: Great care must be taken not to mix sheets: they should all come from the same production batch. This applies for high-profile roofs that are visible to everyone, where any differences in the sheets will affect the visual impact of the building. We therefore advise you to choose Aluzinc® Florelis for this type of roof to ensure that its visual appearance is as uniform as possible.

• NONNONNONNON----visible roofs:visible roofs:visible roofs:visible roofs: Where the roof is not visible, as in the case of industrial buildings or structures over 10 metres high, Aluzinc® Florelis is not required, since the constraints will not be the same. Standard Aluzinc® will amply suffice to cover the building in question. The fact that no one will be able to see the roof also means that a few minor defects in visual appearance will be acceptable.

The result is a new standard in roofing, replacing pure zinc sheets and offering a cost-effective alternative to other metallic solutions.

------------------------------------------------------------ ConclusionsConclusionsConclusionsConclusions Studies carried out in recent years have shown how well Aluzinc® performs, whether it is used for roofing or façades: excellent corrosion resistance, exceptionally long-lasting aesthetic appearance and remarkable formability (bending, profiling etc). ArcelorMittal Flat Carbon Europe therefore backs the Aluzinc® AZ185 coating with a 25-year warranty against corrosion, in the construction sector. The aim of this document is not to prevent every problem that might occur on a worksite, but rather to offer you some guidance to help you optimise any project in which Aluzinc® is used. We therefore strongly advise you to follow the instructions provided to ensure that your project is a complete success, achieving an aesthetically pleasing result that will last for many years!
