Galvalume Roofing, Siding & Flooring
We manufacture galvalume steel panels for roofing, siding and flooring on agricultural and commercial buildings. The steel is formed into a range of corrugated and ribbed siding profiles, and our light gauge galvalume panels cover roofing, siding and industrial enclosures. The sections below explain how galvalume performs and how it compares with galvanized steel.
What Is Galvalume Steel?
Galvalume is sheet steel coated with an alloy of roughly 55 percent aluminum, 43 percent zinc and a small amount of silicon, applied in a continuous hot-dip process. The aluminum forms a barrier that keeps moisture off the steel, while the zinc protects the base metal where it is scratched or cut. The steel underneath supplies the strength, and the coating determines how long the panel lasts outdoors.
Key Benefits of Galvalume
- Corrosion Resistance: The aluminum and zinc coating protects steel from moisture and environmental factors, offering superior resistance to corrosion. This ensures Galvalume products last longer in harsh conditions, reducing the need for frequent maintenance or replacement.
- Durability: Galvalume's steel core provides exceptional strength that withstands years of use. It performs well in extreme weather, handling both hot and cold environments, and resists chemical exposure in challenging conditions.
- Thermal Reflectivity: Galvalume roofing reflects a significant portion of solar heat, contributing to improved energy efficiency and cooler indoor temperatures. This energy-saving property can help reduce building energy costs.
- Aesthetic Appeal: With its metallic finish, Galvalume complements a variety of architectural styles for both residential and commercial projects. It also offers customization options, as it can be painted for added versatility.
- Versatility: Galvalume is flexible and easy to fabricate into various shapes and sizes, such as siding, roofing panels, and even appliances. Its adaptability makes it suitable for several applications, including residential, commercial, and industrial projects.
- Cost Effective: Galvalume is an affordable alternative to other materials like galvanized or stainless steel, offering comparable durability and corrosion resistance. Its long lifespan and low-maintenance properties help reduce overall lifecycle costs, making it a budget-friendly choice.
Common Uses for Galvalume Roofing and Siding
Galvalume does its best work on exposed surfaces, where sun, rain and snow wear on a panel year after year. We supply it for roofing, siding and flooring, covered below.
Galvalume Roofing
Roofs take the most sun and weather, and galvalume is made for that exposure. Its reflective surface keeps heat out in summer, and the coating resists the rust that wears on large roofs over retail spaces, warehouses, barns, silos and other agricultural buildings. Standing seam is a popular galvalume profile because of its strength and ease of installation.
Galvalume Siding
On walls, the aluminum-zinc coating keeps moisture off the steel, so siding on commercial and office buildings, schools and industrial complexes needs little upkeep. The clean metallic finish suits architecture and construction projects, and panels can be painted when a project calls for color. A concealed fastener profile keeps the wall flat and uncluttered.
Galvalume Flooring
Floors see heavy traffic and plenty of moisture. Galvalume's steel core carries the load, and the coating keeps moisture off the steel, which suits factories, loading docks and commercial kitchens. Panels can be cut to the length each floor requires, which keeps seams to a minimum.
Galvalume vs. Galvanized Steel
The zinc coating on galvanized steel protects cut edges and drill holes. Galvalume's coating forms a longer-lasting barrier on exposed surfaces and reflects more heat. Galvanized is the safer choice where panels are cut on site or touch concrete and other alkaline materials. Our team can help you decide which fits your project.
Custom Galvalume Panel Supplier for Roofing and Siding Projects
Instead of limiting you to stock sizes, we cut each galvalume order to the lengths your roof or wall requires. We supply contractors and builders working on agricultural and commercial projects, and we can match panels to a single building or a larger job.

FAQs
Yes. Galvalume accepts paint, and exterior acrylic latex made for galvanized metal is the most common choice. The surface needs to be clean and dry, and new panels with a mill treatment should weather for a few months before painting so the paint adheres.
Galvalume is not the right choice in alkaline environments or where panels touch wet concrete, treated lumber or copper, because those can corrode the coating. It also loses protection where the coating is badly scratched or dented, and where animal waste sits against the panel. In those cases galvanized steel is usually the better fit, and our team can advise on your project.
An industry study of galvalume standing seam roofs projected a service life of 60 years or more with minimal maintenance. Actual life depends on a number of factors, including region, weather conditions, proper maintenance and local rainfall, installation quality and whether the coating is damaged.
