Galvalume® sheet steel with a full 29 gauge metal thickness is the heart of panels from Marco Metals, LLC.
Galvalume® is a carbon sheet steel coated with an alloy of 55% aluminum (for barrier corrosion protection) and 45% zinc (for galvanic protection) through a patented continuous hot dip process. The result is a highly corrosion-resistant material that delivers the optimum features of both aluminum and zinc. In fact, Galvalume’s® performance in the industry has been so superior that steel mill’s warranty it against rupture perforation or failure due to corrosion. Comparable warranties do not exist for galvanized!
Layer 2 – High-performance primers are key to long-term corrosion resistance and paint adhesion.
Layer 3 – Pretreatments provide excellent corrosion resistance and adhesion.
Layer 4 – An aluminum-zinc alloy coating. Quite a force in fighting corrosion.
Layer 5 – Uniform steel sheet properties are a result of modern steelmaking technology.
Layer 6 – Backer coats to enhance corrosion resistance and minimize abrasion damage.
