What is the advantage of galvalume?

Mar 17, 2026

Galvalume is a type of steel coated with an alloy of 55% aluminum and 45% zinc, offering enhanced corrosion resistance compared to galvanized steel. It's a popular choice for metal roofing and siding, and its durability and self-healing properties make it a reliable material for various applications.  

  • Corrosion Resistance: The aluminum in the coating provides barrier protection, while the zinc offers galvanic protection, meaning it sacrifices itself to protect the underlying steel from rust. 

  • Self-Healing: If the coating is scratched or damaged, the zinc will self-heal the exposed area, preventing red rust from spreading 

  • Durability: Galvalume is known for its long-lasting performance, with warranties ranging from 25 to 60 years, depending on environmental conditions. 

  • Aesthetics: It has a distinctive silvery metallic spangle, which is attractive in unpainted applications. 

  • Versatility: It can be pre-painted in various colors and readily painted in the field. 

  • Cost-effectiveness: Galvalume is a relatively affordable metal material for roofing and siding. 

Whether you choose bare galvalume or painted, you are choosing the best material to protect your roof and building. Offered in 29 and 26 at our factory, our panels are made to last and protect your structure for many years to come.
