What is the one thing that comes to mind when you have a roof over your head? Peace of mind?
For absolute peace of mind, make sure that the warranty on your Chromadek® or Chromadek Ultim® roof measures up to certain standards so that it is valid if you need it. ArcelorMittal South Africa suggests three steps:

Step 1: Make sure it’s Chromadek® and Chromadek Ultim®

Authenticity counts in your favour, here’s how to check:

The back of Chromadek® and Chromadek Ultim® roof-sheeting should look like this.

Should there be a need to raise a concern in the future, full traceability assists in providing positive identification and the purchase history of all Chromadek® and Chromadek Ultim®. This is your safeguard, keep in mind that while it may look like Chromadek®, it might not be if any of the above markers are missing.

Chromadek® and Chromadek Ultim® are solely produced by ArcelorMittal South Africa and supplied to established and well-recognised roofing profilers providing the assurance that the preferred choice in colour-coated steel roofing and cladding is covered by a standard warranty.

Step 2: Do the right things before applying for a warranty

Chromadek® draws on design for purpose. At inception, Chromadek® derives its structural strength from its steel core, coated with a metallic zinc coating also known as the galvanised layer. This layer ensures that both the structural integrity and steel core is preserved for functionality.

Once the longevity of the steel core is secured by the metallic zinc coating, Chromadek® is aesthetically enhanced. This, linked to the 14 standard colours available in the African Heritage colour range, makes Chromadek® an instantly recognised colour-coated steel roofing option – an excellent choice in style.

If care is not taken, either the galvanised or the colour-coated layer, or both, can be damaged. In turn, the condition of the roof can influence the validity of a warranty. The following will assist in avoiding damage to the roof before applying for a warranty:

–    Avoid using an angle grinder to cut roof-sheeting as this may generate hot sparks that can embed into the painted layer. Once particles from cutting with an angle grinder are embedded into the painted layer, rusting will usually appear in a short space of time. Should this be the case, the affected roof-sheeting will be excluded from a warranty.

–    Clean or remove all metal deposits after constructing the roof. Loose fasteners, pop-rivet mandrills, metal drillings/objects increase the risk of corrosion and should be removed.

–    Ensure the roof pitch is correct – datasheet C1.4 advises.

–    The correct type and class of fastener must be used for a specific area and regional application – datasheet C1.4 advises.

–    Avoid direct contact between dissimilar metals or alloys not compatible with the metallic zinc coating for Chromadek® and Chromadek Ultim® – datasheet C1.4 advises.

Step 3: Apply for a warranty, it’s easy if you have all the information

When applying, make sure all the vital information on the warranty application is available. The information that is requested includes:

–    The coil numbers used to produce the roof-sheeting. Without this information, the warranty application will not advance

–    The location of the roof-sheeting. Ensure the guidelines in datasheet C1.4 are followed as this will assist in preventing the regional misapplication of Chromadek® and Chromadek Ultim®. In the event that Chromadek® and Chromadek Ultim® are subject to regional misapplication, this will automatically disqualify the roof from a warranty.

If in doubt, consult datasheet C1.4, available at www.chromadek.com, before proceeding with a roof installation.

Following these three easy steps when using Chromadek® and Chromadek Ultim® will give you the peace of mind that your choice of roofing is not only an excellent choice in style but is also assured under a valid warranty.
