Magnificent Magnelis®

Magnelis® is a premium metallic coating on flat carbon steel for the construction and energy market segments. Thanks to its outstanding corrosion resistance – at least 3 times better than regular hot dip galvanised steel – Magnelis® contributes to raw material (Zn) preservation and CO2 emission reduction.

CUSTOMERS’ FAVOURITE

The Magnelis® process and product technology has a strong patent portfolio of more than 10 patent families. Its dedicated commercial approach resulted in a successful ramp-up, unseen in the industry segment: not only do customers shift easily from commodity coatings to Magnelis®, but they also identify future applications. This unprecedented growth needs to be underpinned by strong R&D project leadership: managing the multi-year plan to open more production lines or transform existing galvanising lines into Magnelis® production within the ArcelorMittal group. OCAS is playing an important role to ensure sufficient capacity. Whereas the full R&D team provides the necessary support, the OCAS team guides the production evaluation and validation, based on product appearance and other properties. Because of the high added value of Magnelis® with respect to corrosion resistance, the trend is to promote this material in extremely corrosive environments. These specific environments require dedicated research programs. A first step is to increase the coating weight of Magnelis® beyond the current catalogue. A dedicated support team is guiding some production lines to cope with the different challenges, such as the robustness of the process and avoiding defects linked to high coating weights. Dedicated research on the product performance of this new product extension is also underway – investigating its in-use properties in addition to its corrosion performance. Meanwhile, a next generation of metallic coatings are already being developed in the innovative metallic coatings platform (IMpACT) to bring the durability of metallic coatings to the next level. Efforts are being focused on improving the performance of metallic coatings for highly demanding applications. Some promising concepts are already being evaluated on pilot scale.
