ZALMAG® is a steel based product with a unique coating consisting of Zinc, Aluminum and Magnesium.

ZALMAG® is a highly corrosion – resistant, hot dip coated steel that has a coating layer of Zinc, Aluminum, and Magnesium. Additionally, ZALMAG® has superior scratch resistance with unique self-healing characteristics that make it the perfect material for perforating and a great solution for all environments.


The beauty and magic of ZALMAG® is that every application is different. Depending on the temperature, humidity, and alkalinity of your location, the patina process can start at different rates (days to years) adding visual interest and character at every step of the journey. ZALMAG® makes any architectural application a living transformation project.

ZALMAG® surfaces (Natural, Pre-Patina II, and Black) will age in a random order to grey tones. Grey-to-white marks can appear on ZALMAG®’s surfaces; these marks do not adversely affect the material’s lifespan but add to it's forever-changing characteristic. ZALMAG® reacts to the environment, handling, installation, and equipment pressure. Due to the nature of ZALMAG®, it will self-heal cuts and perforations and it will naturally patina based on handling and the surrounding environment.

The Ultimate in Corrosion Resistance

The Zalmag® coating is a blend of zinc, aluminum and magnesium. The small quantities of magnesium (3%) and aluminum (6%) combine to form a protective barrier on the surface of the coating over time. The fine, strongly attached barrier creates a two-layer structure on the surface of the steel, suppressing corrosion resistance of the product. With a corrosion resistance at least 3 times that of zinc galvanized steel for the same coating mass, Zalmag® products can be used in environments subject to extremely corrosive conditions.

Excellent corrosion resistance is achieved on cut end parts by the sacrificial anti-corrosive effect of the coating. Initially, cut edges may display signs of red rust, but this will change color over time as the protective mechanism converts the red rust to a grey-black, highly corrosion resistant coating. The color tone and the speed at which the tone changes vary depending on the exposure environment (region, installation location, orientation, etc.) A slit coil shows the results of self-healing within just two weeks.
