Product Introduction

Galvalume steel coil is a high-quality carbon steel product coated with a unique alloy composition of 55% aluminum, 43.4% zinc, and 1.6% silicon. This advanced coating provides exceptional corrosion resistance, heat reflectivity, and formability, making it ideal for a wide range of industrial and construction applications. Available in thicknesses ranging from 0.12mm to 4.0mm and widths from 30mm to 1500mm, our Galvalume coils offer superior protection and longevity compared to traditional galvanized steel.

Key Features & Advantages

Galvalume steel coils combine the best properties of aluminum and zinc, offering 2-4 times longer lifespan than conventional galvanized steel. The aluminum component ensures excellent heat resistance (up to 315°C), while zinc provides sacrificial protection against rust. Its lightweight yet durable structure makes it cost-effective for roofing, cladding, and automotive parts. Additionally, the silicon layer enhances adhesion, preventing coating peeling during forming or welding.

Applications & Technology

Widely used in construction (roofing, wall panels), appliances, automotive components, and HVAC systems, Galvalume steel is engineered for harsh environments. The continuous hot-dip coating process ensures uniform protection, while advanced passivation treatments improve paint adhesion. Its high reflectivity reduces cooling costs in buildings, making it an eco-friendly choice. With superior weather resistance and minimal maintenance, Galvalume coils deliver long-term performance and sustainability. AluZinc™ 55% Al-Si Coated HD Coil Galvalume 0.12-3.0mm 1500mm
