Lindab Magestic is an improved galvanised steel material for rainwater system and standing seam applications. Magestic offers the same trusted Lindab product designs with a strengthened magnesium zinc alloy coating. Galvanised steel is already the most environmentally friendly material used in rainwater systems. Magestic has a reduced impact on zinc resources and less than 25% zinc run off into soils compared to hot dipped galvanised steel. New technology has allowed the material to be developed using magnesium to create a stable barrier to protect zinc’s porous structure against corrosion factors. Salt spray tests demonstrate the highest surface protection of any metallic coated steel. Magestic has more than twenty times the corrosion resistance of hot dipped galvanised steel. Unpainted metal gutters naturally weather organically adjusting to the installation environment. Magestic settles to an attractive dark grey metallic appearance within 3-5 years after installation. Magestic corrosion in not influenced by the chlorine content of the environment. Natural exposure tests demonstrate more than three times the corrosion resistance of standard galvanisation in marine environments. Galvanised coatings migrate to repair red rust on cuts and scratches. Magnesium is more anodic than zinc making the sacrificial properties of Magestic more active than standard galvanisation.
