MagnaGuard™ Steel Coil & Sheet Metal
Pre-Painted Aluminum-Zinc-Magnesium Carbon Steel
ZM150
MagnaGuard™ is an alloy-coated carbon steel offering advanced protection for today's metal roofing and metal wall panel systems. Similar to Galvalume® but with the added strength of Magnesium, MagnaGuard™ features a coated layer of 55% aluminum, 43.4% zinc-magnesium and 1.6% silicon-magnesium over carbon steel - delivering improved resistance to corrosion in extreme environments and enhanced protection against failure from cuts and scratches. Available pre-painted with Fluropon® 70% PVDF with Kynar 500® in nearly 40 colors.
ADVANTAGES OF MAGNAGUARD™
- Improved resistance to highly corrosive environments including coastal and industrial
- Advanced self-sealing protection at cut edges and scratches for long-term durability
- Surface hardness for improved abrasion resistance, reduced handling damage
- High heat resistance and reflectivity
- Outstanding coating adhesion
- Excellent formability and adhesion
- Available in nearly 40 colors
MagnaGuard™ Quick Reference
Each type of protective alloy has its own physical and mechanical properties, all with important factors in determining the longevity, strength, and overall performance of the coating. While Galvalume® is a premium product with many advantages, it's protection of the underlying metal from corrosion is reduced at scratches and cut edges which can ultimately lead to premature substrate failure. AL-ZN coated steel is also not recommended in coastal environments since the sodium chloride in salt spray will prematurely break down the coating and compromise the underlying metal roof or wall system.
MagnaGuard™ offers all the protective properties of aluminum and zinc in prolonging the life of underlying steel. Adding magnesium to the formula works to intensify the beneficial effects of both zinc and aluminum at just the right time to produce a self-healing reaction that offers advanced protection of the substrate at cut edges and scratches.
