Why choose chromadek roof sheeting


The advantages of Chromadek® roof sheeting include better edge protection and reduced risk of formability cracking that could cause corrosion issues. All Chromadek® and Chromadek Ultim® sheets are labeled on the back. Only ArcelorMittal South Africa produces Chromadek®, which is a registered trademark. Choosing Chromadek® means the product has undergone thorough testing and comes with technical support.



Features and Benefits


Chromadek boasts a range of features that make it an attractive choice for architects, engineers and builders alike. At the forefront is its unparalleled resistance to corrosion and color fading, ensuring a long-lasting and aesthetically pleasing finish. In addition, its superior durability, strength and ease-of-installation make it a popular choice for commercial, industrial and domestic use.

From a sustainability perspective, Chromadek also offers a range of benefits. For instance, being a lightweight material means that it requires less energy to transport and install compared to heavier options. It is also made from recyclable materials and can be repurposed at the end of its life, reducing its overall environmental impact.




Chromadek Applications


Chromadek's versatility is apparent in its numerous applications across a range of industries. Its popularity stems from the fact that it can be used for roofing, cladding and even gutters. This flexibility makes it a go-to choice for projects that require uniformity in design, such as warehouses, agricultural structures, and low-cost housing.


Despite being a lightweight option, Chromadek is also an ideal solution for areas that experience high winds, as it has the ability to be easily installed on roofs with a low pitch. Additionally, its wide range of colors means it can be customized to suit any design aesthetic, enhancing the overall appeal of a project.


Considerations when using Chromadek


When choosing Chromadek as your preferred roofing and cladding solution, it is important to note that installation should be done by qualified professionals. This will ensure that the material is installed to the required specification, and that warranties and guarantees are in place.


It is also important to consider the overall cost and available contractors for installation. While Chromadek is a superior product, its initial cost may be higher than certain alternatives. Regardless, the long-term benefits of using Chromadek, such as its durability and resistance to environmental factors, make it a wise investment in the long run.

Taking care of your chromadek roof sheets


  • After you finish the roof, make sure to clean or get rid of any metal residue such as loose fasteners, pop-rivet mandrills, and metal drillings/objects. Failure to do so may heighten the risk of corrosion.


  • To avoid corrosion, it is important to prevent damage to the paint coating. Severe damage can increase the risk of corrosion, especially in areas where it is already present such as overlapping sheets and sheet ends. To prevent further corrosion, thoroughly clean any corroded edges and repaint them in a timely manner.


  • If you need to paint a Chromadek® roof, you can do so by using the right roof preparation method and paint system. You can consult Arcelor Mittal South Africa for advice and to get referred to roofing finishers who are approved and reputable.


  • When walking on roofs, it is better to use soft contact instead of abrasive contact.


  • Regular cleaning and washing of roofs are recommended as part of scheduled roof maintenance.

  • The appropriate type and class of fasteners must be utilized for a particular region and application.

  • For installing solar panels, it is advised to use galvanised fixtures. However, it is important to use the proper class of fastener and ensure metal compatibility.

  • To cut Chromadek® roof sheets, it is recommended to avoid using angle grinders to prevent swarf and sparks. Instead, suggested alternatives are using circular saws and nibblers for cutting.


  • To avoid damaging the roof sheets and coils, it is important to store them indoors in a covered and enclosed storage area. Do not leave them outside in wet conditions. Make sure the storage area has proper ventilation.
