What is Magnelis® steel

What is Magnelis® steel

Magnelis® Zinc Aluminum Magnesium Steel (ZM steel) is provided in a molten bath with a zinc alloy with a unique chemical composition of 3.5% aluminum and 3% magnesium. As a specialist in Zinc Magnesium steel strip and plate, KS Service Center has a wide range of grades and thicknesses with short lead times available!

  • Why is Magnelis® steel 10 times more resistant to corrosion than galvanized steel?
  • What makes Magnelis® steel the best protective cladding in aggressive environments?
  • Why is Magnelis® steel a cheaper alternative to the piece galvanizing process?
  • Why is it that Zinc Aluminum Magnesium steel is more environmentally friendly than other galvanized steels?

After reading this text, you will know why Magnelis® steel is better protected against corrosion, more durable and a cheaper alternative.


Magnelis®, offered by KS Service Center, is an innovative coating that provides exceptional corrosion protection for a wide range of applications. Magnelis® sheets and strip steel are treated with a zinc-aluminum-magnesium alloy that extends their lifespan and delivers superior performance compared to traditional galvanized products. This coating offers up to 70% longer durability than conventional Sendzimir zinc coatings.

Magnelis® steel is ideal for structural applications where durability is crucial, such as in the construction, automotive, and solar energy sectors. This material not only effectively combats corrosion but also promotes sustainability through its environmentally friendly production process, making it an excellent choice for projects aiming to reduce their ecological impact.

KS Service Center offers Magnelis® in a variety of dimensions and formats, including slit steel in coils, tailored to meet the individual needs of our customers. We ensure that all our Magnelis® steel meets the highest quality standards and is ready for use in demanding environments.

With our team of experts, we are ready to advise you on how Magnelis® can enhance the efficiency and sustainability of your projects.

SUPERIOR CORROSION RESISTANCE

An extensive 8-month testing period showed that no other product offers better protection in chloride environments (coastal areas, swimming pool) or ammonia environments (barn, farm) than Magnelis®. ZM steel offers better corrosion resistance than standard hot-dip galvanized steel. In an ammonia environment, a Magnelis® cladding will corrode seven times less than a standard zinc cladding.


In acidic environments with a pH between 10 and 13, Magnelis® offers better corrosion resistance than other metallic coatings. The chemical composition of the product provides a stronger barrier to corrosion in ammonia environments.

Best protection in chloride or ammonia environments.

In acidic environments such as vineyards and greenhouses with pH between 10 and 13, Magnelis® offers better corrosion resistance than other metallic coatings. The chemical composition of the product provides a stronger barrier to corrosion in ammonia environments.

Self-healing ability

Just like your skin, this Zinc Aluminum magnesium alloy steel can heal itself. The  Magnelis® ZM steel is designed so that the coating has a self-healing ability to treat scratches, perforations and cut edges by chemical reaction. 

Perfect alternative to piece galvanizing, stainless steel and aluminum

Magnelis® is much lighter compared to the subsequent hot-dip galvanizing of steel products. A -depending on the environment- 2 to 4 times lighter zinc layer can be used, while the corrosion resistance is considerably better and the product is cheaper. Because there is one less link in the production chain, less personnel and transportation are required.

Did you know that Magnelis® steel protects against corrosion just as well against high-performance products like stainless steel and aluminum while costing less?


More durable

In addition to being highly corrosion resistant, ZM steel is also more environmentally friendly than products with pure zinc coatings.

  • Lower zinc consumption compared to pure zinc coatings.
  • Significantly lower zinc run-off rate.
  • Less dirt deposition when processing the steel than with regular zinc.
