Lindab Magestic is flat steel with an innovative zink-magnesium surface coating consisting of 3 percent magnesium, 3.5 percent aluminium and the rest zinc and it is usable in corrosion class up to C4. Lindab Magestic is created to cope with the toughest environments with sea salt or other areas with chloride and ammonia. This durable material also ages with dignity and patinas over time. The Lindab Magestic steel is delivered in wide coils, slit coils, or sheets. It can be processed by conventional processing operations such as bending, drawing, clinching, profiling, stamping, welding etc. Zink-magnesium coated steels are available in thickness range of 0.60 – 2.0 mm and widths up to 1500 mm, and contains approximately 20% of recycled scrap steel. Lindab Magestic protects the steel from corrosion in two ways. It serves as a protective layer keeping oxygen and water away from the steel, but it also acts as a cathodic protection. This means that at cut edges or in case of damages through the metal coating, the coating will sacrifice itself and react to form protective compounds and block further corrosion processes. The zink-magnesium coating covers the steel on both sides. In addition, Lindab Magestic can improve formability, resistance welding properties and paintability.
