ETP Coil Specification
-
Galvalume steel is manufactured using carbon steel or low-alloy steel as the base substrate. These materials offer excellent strength, structural stability, and formability, making them suitable for roofing, cladding, fabrication, and industrial applications.
-
Unlike traditional galvanized steel, Galvalume is coated with an advanced aluminum-zinc alloy consisting of approximately 55% Aluminum, 43.5% Zinc, and 1.5% Silicon.
This metallic combination provides superior corrosion resistance, heat reflectivity, and long-term durability compared to standard zinc-coated steel.
-
The coating is applied using a continuous hot-dip process. The cleaned steel substrate is immersed in molten aluminum-zinc alloy, forming a strong metallurgical bond.
During exposure, aluminum reacts with oxygen to create a protective aluminum oxide barrier that significantly enhances surface protection.
-
Galvalume coils offer exceptional resistance against rust, oxidation, and harsh environmental conditions.
They perform especially well in coastal regions, industrial zones, and high-humidity environments where long-term corrosion protection is critical.
Galvalume Coil Trade Information
Aluminum-Zinc Alloy Coated Steel
Galvalume steel is manufactured using carbon or low-alloy steel as the base material, coated with a unique aluminum-zinc alloy. The 55% aluminum, 43.5% zinc, and 1.5% silicon composition delivers enhanced protection compared to traditional galvanized steel.
Advanced Hot-Dip Process
The coating is applied through a continuous hot-dip process where the steel substrate is immersed in molten aluminum-zinc alloy. This forms a protective aluminum oxide layer that significantly improves corrosion resistance and surface durability.
Superior Corrosion Protection
Galvalume coils provide exceptional resistance against rust and environmental exposure, making them ideal for coastal regions, industrial zones, and high-humidity conditions requiring long-term structural reliability.
Wide Industrial Applications
Commonly used in roofing, wall cladding, architectural panels, gutters, automotive components, agricultural equipment, and industrial machinery where durability, longevity, and cost efficiency are essential.
