About Galvalume Steel
Premium Corrosion-Resistant Coating for Lasting Durability
Industry-Leading Protection for Your Metal Building Investment
At ArchBuildings.com, we value quality above all else. We understand that you're making a significant investment in a new steel building, and you deserve complete confidence that your structure is built to last. That's why we use premium Galvalume coated steel in every single one of our metal building kits. But what exactly is Galvalume, and why does it matter for your building?
What is Galvalume Steel?
The science behind superior protection
Galvalume is a revolutionary aluminum-zinc-silicon alloy coating that is applied to steel through a continuous hot-dip process, similar to traditional galvanization but significantly more advanced. This proprietary coating combines the best properties of both aluminum and zinc to create a protective barrier that far exceeds the performance of standard galvanized steel.
The coating consists of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This precise combination creates a unique microstructure with alternating zinc-rich and aluminum-rich zones that work together to provide exceptional corrosion resistance. The aluminum component provides long-term durability and heat reflectivity, while the zinc offers sacrificial corrosion protection, creating a self-healing barrier that protects your building for decades.
Galvalume steel is the equivalent of 16-gauge steel in thickness, providing substantial structural strength while maintaining the corrosion-resistant benefits of the coating. When combined with our premium hardware components, you're guaranteed a rugged, dependable steel structure that will stand the test of time.
Why Choose Galvalume Over Other Coatings?
The ArchBuildings.com advantage
Superior Corrosion Resistance
Galvalume provides 2-4 times better corrosion protection than standard galvanized steel. The aluminum-zinc alloy creates a barrier that resists rust, oxidation, and environmental degradation far longer than traditional coatings.
Heat Reflectivity
The aluminum content in Galvalume reflects solar heat, keeping your building cooler in summer months. This reduces energy costs and creates a more comfortable interior environment for your equipment, vehicles, or livestock.
Long-Term Durability
Galvalume's unique microstructure provides long-lasting protection that maintains its integrity even in harsh environments. Our 35-year warranty reflects our confidence in this superior material.
Cost-Effective Solution
While Galvalume may cost slightly more upfront than galvanized steel, its extended lifespan and reduced maintenance requirements make it the most economical choice over the lifetime of your building.
Weather Resistance
Galvalume performs exceptionally well in all weather conditions, from coastal salt air to heavy snow loads, extreme temperatures, and high humidity. Your building stays protected year-round.
Paint Adhesion
If you choose to paint your building, Galvalume provides an excellent surface for paint adhesion, ensuring your custom color scheme lasts longer and looks better than on other steel coatings.
