When selecting the right material for your metal roof, metal siding, or custom trim, it’s essential to understand your options. Two of the most common choices are Galvalume and galvanized steel—both of which offer excellent durability and protection. But how do they differ, and which one is best for your project?
At Ramco Metal Roofing, we manufacture high-quality metal roofing and siding using both Galvalume and galvanized steel, ensuring you get the best material for your needs.
What is Galvanized Steel?
Galvanized steel is created by dipping steel into molten zinc, which forms a protective outer layer. This coating helps the steel resist corrosion, rust, and surface damage, making it a widely used material in construction and manufacturing.
Key Benefits of Galvanized Steel:
✔ Strong and impact-resistant – Holds up well against dents and scratches
✔ Cost-effective – More affordable than Galvalume
✔ Corrosion-resistant – Ideal for general roofing and siding applications
With proper installation and minimal maintenance, a galvanized steel roof can last 15-20 years, making it a practical choice for budget-conscious buyers who still want durability.
What is Galvalume?
Galvalume steel is coated with a blend of 55% aluminum, 43.4% zinc, and 1.6% silicone, providing even greater protection against weather, moisture, and temperature extremes.
Key Benefits of Galvalume Steel:
✔ Superior corrosion resistance – Lasts up to twice as long as galvanized steel
✔ Lightweight and durable – Ideal for both residential and commercial applications
✔ Reflective properties – Enhances energy efficiency and reduces heat absorption
Because of its enhanced durability, Galvalume is an excellent choice for metal roofing, siding, and custom trim in areas with high humidity, heavy rainfall, snowfall, or extreme temperatures.
Galvanized vs. Galvalume: What’s the Difference?
The biggest distinction between these two materials is the protective coating:
- Galvanized steel has a zinc-only coating, providing excellent protection but requiring more maintenance over time.
- Galvalume steel features a combination of zinc, aluminum, and silicone, making it more resistant to rust and corrosion in harsh environments.
Both materials are great for metal roofing and siding, but Galvalume offers greater longevity, while galvanized steel is a more budget-friendly option.
Which One is Right for You?
Choosing between Galvalume and galvanized steel depends on your budget, climate, and durability needs.
- If you need cost-effective protection and are working within a limited budget, galvanized steel is a solid choice.
- If you want longer-lasting protection with enhanced corrosion resistance, Galvalume is the better investment.
