Competitive Price GL Coil Anti-Finger Prepainted Galvalume Steel Coil Metal Roofing Coil
Galvalume steel coils are steel coils coated with a layer of aluminum-zinc alloy. This coating provides excellent corrosion resistance and heat reflectivity, making them suitable for various applications, including construction, appliances, and automotive parts. The coating typically consists of 55% aluminum, 43.4% zinc, and 1.6% silicon.
Key characteristics of Galvalume steel coils:
Corrosion Resistance:
The aluminum-zinc alloy coating offers superior protection against rust and corrosion compared to traditional galvanized steel.
Heat Reflectivity:
Galvalume's high aluminum content provides excellent heat reflectivity, making it suitable for applications like roofing and appliances where heat management is important.
Durability:
The combination of aluminum and zinc in the coating provides a durable and long-lasting material.
